There is recent scientific evidence from drill core sampling in Manhattan, that the southern peninsula is overlapped by several tectonic plates. Drill core sampling has been taken from regions south of Canal Street including the Trade Towers’ site. Of particular concern is that similar core samples have been found across the East River in Brooklyn. There are also multiple fault lines along Manhattan correlating with north-northwest and northwest trending neo-tectonic activity. And as recently as January and October of 2001, New York City has sustained earthquakes along these plates. For there are “two great rocks” or tectonic plates that shear across Manhattan in a northwestern pattern. And these plates “for a longtime will make war”, for they have been shearing against one other for millions of years. And on January 3 of 2010, when they makewar with each other one last time, the sixth seal shall be opened, and all will know that the end is near.
And then Arethusa will color a new river red.
Arethusa is a Greek mythological figure, a beautiful huntress and afollower of the goddess Artemis. And like Artemis, Arethusa would have nothing to do with me; rather she loved to run and hunt in the forest. But one day after an exhausting hunt, she came to a clear crystal stream and went in it to take a swim. She felt something from beneath her, and frightened she scampered out of the water. A voice came from the water, “Why are you leaving fair maiden?” She ran into the forest to escape, for the voice was from Alpheus, the god of the river. For he had fallen in love with her and became a human to give chase after her. Arethusa in exhaustion called out to Artemis for help, and the goddess hid her by changing her into a spring.But not into an ordinary spring, but an underground channel that traveled under the ocean from Greece to Sicily. But Alpheus being the god of the river, converted back into water and plunged downthe same channel after Arethusa. And thus Arethusa was captured by Artemis, and their waters would mingle together forever. And of great concern is that core samples found in train tunnels beneath the Hudson River are identical to those taken from southern Manhattan. Furthermore, several fault lines from the 2001 earthquakes were discovered in the Queen’s Tunnel Complex, NYC Water Tunnel #3. And a few years ago, a map of Manhattan drawn up in 1874 was discovered, showing a maze of underground waterways and lakes. For Manhattan was once a marshland and labyrinth of underground streams. Thus when the sixth seal is broken, the subways of the New City shall be flooded be Arethusa:the waters from the underground streams and the waters from the sea. And Arethusa shall be broken into two. And then Arethusa will color a new river red.
And then areth USA will color a new river red.
For Arethusa broken into two is areth USA. For areth (αρετη) is the Greek word for values. But the values of the USA are not based on morality, but on materialism and on wealth. Thus when the sixth seal is opened, Wall Street and our economy shall crash and “arethUSA”, the values of our economy shall fall “into the red.” “Then the kings of the earth and the great men and the commanders and the rich and the strong and every slave and free man hid themselves in the caves and among the rocks of the mountains; and they said to the mountains and to the rocks, ‘Fall on us and hide us from the presence of Him who sits on the throne, and from the wrath of the Lamb; for the great day of their wrath has come, and who is able to stand?’” (Revelation 6:15-17)
Reports of Vanderbilt skyscraper having major shakes caused chaos in New York City
Donald Trump’s possible arrest is not the only news coming from New York City, there were real moments of panic taking place at the One Valderbilt skyscraper. People inside the building felt some major shakes that made many believe an earthquake was taking place in the city. As all were evacuated, many realized there was no earthquake happening at all. But these shakes were extremely violent, everybody wodered what happened to the building. A spokesperson for Vanderbilt tower revealed the shakes were produced by an elevator malfunction. But this reason doesn’t feel right for many Twitter users who are getting to read the news.
When was the One Vanderbilt skyscraper constructed?
Worth $3.3 billion and with a 98-feet height, the One Vanderbilt skyscraper is one of New York City’s tallest towers. One would think an old tower could shake more than a recently-built one, but one would be wrong. The One Venderbilt skyscraper was built two years ago and it is one of the town’s most important touristic attractions. People who go to New York can pay $39 for admission to the tower to $59 for folks who want to experience the glass elevator, which rises 12 more stories. The place where the elevator malfunction took place was at the Summit One Vanderbilt, which has an outdoor terrace over 1,200 feel in the air. Those elevators are made of clear glass.
People who were inside the building are tweeting and offering more details about the incident. One user named @DevineBridgette wrote: “Working at One Vanderbilt today and it felt like the floor dropped 5 feet and continued to bounce. Evacuation to Madison Avenue and multiple floors are reporting this. 13, 33, and 60. So far they say they are investigating and there is ‘no cause for concern’. It is very scary,” wrote the user on Twitter. There are multiple reports like this one telling the same experience. So far, it all appears to have been a major scare. But that’s all, for now.
NEW YORK IS 40 YEARS OVERDUE A MAJOR EARTHQUAKE AND AMERICA ISN’T PROPERLY PREPARED, ‘QUAKELAND’ AUTHOR KATHRYN MILES TELLS TREVOR NOAH BY TUFAYEL AHMED ON 9/27/17 AT 9:28 AM Updated | An earthquake is long overdue to hit New York and America isn’t prepared, author and environmental theorist Kathryn Miles told Trevor Noah on Tuesday’s Daily Show. Miles is the author of a new book, Quakeland, which investigates how imminently an earthquake is expected in the U.S. and how well-prepared the country is to handle it. The answer to those questions: Very soon and not very well. “We know it will, that’s inevitable, but we don’t know when,” said Miles when asked when to expect another earthquake in the U.S. She warned that New York is in serious danger of being the site of the next one, surprising considering that the West Coast sits along the San Andreas fault line. “New York is 40 years overdue for a significant earthquake…Memphis, Seattle, Washington D.C.—it’s a national problem,” said Miles. Miles told Noah that though the U.S. is “really good at responding to natural disasters,” like the rapid response to the hurricanes in Texas and Florida, the country and its government is, in fact, lagging behind in its ability to safeguard citizens before an earthquake hits. “We’re really bad at the preparedness side,” Miles responded when Noah asked how the infrastructure in the U.S. compares to Mexico’s national warning system, for example. “Whether it’s the literal infrastructure, like our roads and bridges, or the metaphoric infrastructure, like forecasting, prediction, early warning systems. Historically, we’ve underfunded those and as a result we’re way behind even developing nations on those fronts.” Part of the problem, Miles says, is that President Donald Trump and his White House are not concerned with warning systems that could prevent the devastation of natural disasters. “We can invest in an early warning system. That’s one thing we can definitely do. We can invest in better infrastructures, so that when the quake happens, the damage is less,” said the author. “The scientists, the emergency managers, they have great plans in place. We have the technology for an early warning system, we have the technology for tsunami monitoring. But we don’t have a president that is currently interested in funding that, and that’s a problem.” This article has been updated to reflect that Miles said New York is the possible site of an upcoming earthquake, and not the likeliest place to be next hit by one.
History of earthquakes in Lower Hudson ValleySwapna Venugopal Ramaswamy 9:05 a.m. ET Feb. 7, 2018 At around 6:14 a.m. this morning, a 2.2-magnitude earthquake was reported about three miles northwest of Mohegan Lake in Yorktown, according to the United States Geological Survey. The epicenter of the quake was in Putnam Valley. Social media was rife with posts on the quake with people from Chappaqua, Cortlandt, Lewisboro, Mahopac and Putnam Valley chiming in with their rattling experiences, though it wasn’t nearly as strong as the 5.0 earthquake our forefathers experienced here in 1783. Lower Hudson Valley earthquakes through the years: 1783 — The epicenter of a magnitude 5.0 earthquake may have been the Westchester-Putnam county line and was felt as far south as Philadelphia. 1884 — A magnitude 5.2 earthquake was centered off Rockaway, Queens, causing property damage but no injuries to people. A dead dog was reported. 1970 to 1987 — Between these years, instruments at the Lamont-Doherty Observatory in Rockland County recorded 21 quakes in Westchester and two in Manhattan. October 1985 — A magnitude 4.0 earthquake was centered in an unincorporated part of Greenburgh between Ardsley and Yonkers. Tremors shook the metropolitan area and were felt in Philadelphia, southern Canada and Long Island. November 1988 — A quake 90 miles north of Quebec City in eastern Canada registered magnitude 6.0 with tremors felt in the Lower Hudson Valley and New York City. June 1991 — A 4.4-magnitude quake struck west of Albany, rattling homes. April 1991 — A quake registering between magnitude 2.0 and 2.6 struck Westchester and Fairfield, Conn. It lasted just five seconds and caused no damage. https://tpc.googlesyndication.com/safeframe/1-0-15/html/container.html January 2003 — Two small earthquakes struck the area surrounding Hastings-on-Hudson. One was a magnitude of 1.2, the other 1.4. March 2006 — Two earthquakes struck Rockland. The first, at 1.1 magnitude, hit 3.3 miles southwest of Pearl River; the second, 1.3 magnitude, was centered in the West Nyack-Blauvelt-Pearl River area. July 2014 — “Micro earthquake” struck, 3.1 miles beneath the Appalachian Trail in a heavily wooded area of Garrison. January 2016 — A 2.1 magnitude earthquake occurred at 12:58 a.m. northwest of Ringwood, N.J., and the earthquake was felt in the western parts of Ramapo, including the Hillburn and Sloatsburg areas. April 2017 — A 1.3 magnitude quake rumbled in Pawling on April 10. Putnam County residents in Brewster, Carmel, Patterson and Putnam Valley, as well as Dutchess County residents in Wingdale felt the earthquake. Twitter: @SwapnaVenugopal
America’s Next Big QuakeDoug Fabrizio The devastation wrought in Mexico City by a recent massive earthquake may have rattled more than a few nerves along the Wasatch Front. Salt Lake City is, of course, overdue for a significant seismic event. So are other places in the United States, such as Los Angeles, the Pacific Northwest, even New York City. In a new book, science writer Kathryn Miles tours the country in search of the latest research on America’s next big earthquake and what’s being done to address the threat. She joins us Wednesday to talk about it.

Sloshing of Earth’s core may spike major earthquakesBy Paul VoosenOct. 30, 2017 , 1:45 PM The number of major earthquakes, like the magnitude-7 one that devastated Haiti in 2010, seems to be correlated with minute fluctuations in day length. SEATTLE—The world doesn’t stop spinning. But every so often, it slows down. For decades, scientists have charted tiny fluctuations in the length of Earth’s day: Gain a millisecond here, lose a millisecond there. Last week at the annual meeting of the Geological Society of America here, two geophysicists argued that these minute changes could be enough to influence the timing of major earthquakes—and potentially help forecast them. During the past 100 years, Earth’s slowdowns have correlated surprisingly well with periods with a global increase in magnitude-7 and larger earthquakes, according to Roger Bilham of the University of Colorado (CU) in Boulder and Rebecca Bendick at the University of Montana in Missoula. Usefully, the spike, which adds two to five more quakes than typical, happens well after the slow-down begins. “The Earth offers us a 5-years heads up on future earthquakes, which is remarkable,” says Bilham, who presented the work. Most seismologists agree that earthquake prediction is a minefield. And so far, Bilham and Bendick have only fuzzy, hard-to-test ideas about what might cause the pattern they found. But the finding is too provocative to ignore, other researchers say. “The correlation they’ve found is remarkable, and deserves investigation,” says Peter Molnar, a geologist also at CU. The research started as a search for synchrony in earthquake timing. Individual oscillators, be they fireflies, heart muscles, or metronomes, can end up vibrating in synchrony as a result of some kind of cross-talk—or some common influence. To Bendick, it didn’t seem a far jump to consider the faults that cause earthquakes, with their cyclical buildup of strain and violent discharge, as “really noisy, really crummy oscillators,” she says. She and Bilham dove into the data, using the only complete earthquake catalog for the past 100 years: magnitude-7 and larger earthquakes. In work published in August in Geophysical Research Letters they reported two patterns: First, major quakes appeared to cluster in time —although not in space. And second, the number of large earthquakes seemed to peak at 32-year intervals. The earthquakes could be somehow talking to each other, or an external force could be nudging the earth into rupture. Exploring such global forces, the researchers eventually discovered the match with the length of day. Although weather patterns such as El Nino can drive day length to vary back and forth by a millisecond over a year or more, a periodic, decades-long fluctuation of several milliseconds—in particular, its point of peak slow down about every three decades or so—lined up with the quake trend perfectly. “Of course that seems sort of crazy,” Bendick says. But maybe it isn’t. When day length changes over decades, Earth’s magnetic field also develops a temporary ripple. Researchers think slight changes in the flow of the molten iron of the outer core may be responsible for both effects. Just what happens is uncertain—perhaps a bit of the molten outer core sticks to the mantle above. That might change the flow of the liquid metal, altering the magnetic field, and transfer enough momentum between the mantle and the core to affect day length. Seismologists aren’t used to thinking about the planet’s core, buried 2900 kilometers beneath the crust where quakes happen. But they should, Bilham said during his talk here. The core is “quite close to us. It’s closer than New York from here,” he said. At the equator, Earth spins 460 meters per second. Given this high velocity, it’s not absurd to think that a slight mismatch in speed between the solid crust and mantle and the liquid core could translate into a force somehow nudging quakes into synchrony, Molnar says. Of course, he adds, “It might be nonsense.” But the evidence for some kind of link is compelling, says geophysicist Michael Manga of the University of California, Berkeley. “I’ve worked on earthquakes triggered by seasonal variation, melting snow. His correlation is much better than what I’m used to seeing.” One way or another, says James Dolan, a geologist at the University of Southern California in Los Angeles, “we’re going to know in 5 years.” That’s because Earth’s rotation began a periodic slow-down 4-plus years ago. Beginning next year, Earth should expect five more major earthquakes a year than average—between 17 to 20 quakes, compared with the anomalously low four so far this year. If the pattern holds, it will put a new spin on earthquake forecasting. doi:10.1126/science.aar3598
Earthquakes May Endanger New York More Than Thought, Says Study A study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed. Among other things, they say that the controversial Indian Point nuclear power plants, 24 miles north of the city, sit astride the previously unidentified intersection of two active seismic zones. The paper appears in the current issue of the Bulletin of the Seismological Society of America. Many faults and a few mostly modest quakes have long been known around New York City, but the research casts them in a new light. The scientists say the insight comes from sophisticated analysis of past quakes, plus 34 years of new data on tremors, most of them perceptible only by modern seismic instruments. The evidence charts unseen but potentially powerful structures whose layout and dynamics are only now coming clearer, say the scientists. All are based at Columbia University’s Lamont-Doherty Earth Observatory, which runs the network of seismometers that monitors most of the northeastern United States. Lead author Lynn R. Sykes said the data show that large quakes are infrequent around New Yorkcompared to more active areas like California and Japan, but that the risk is high, because of the overwhelming concentration of people and infrastructure. “The research raises the perception both of how common these events are, and, specifically, where they may occur,” he said. “It’s an extremely populated area with very large assets.” Sykes, who has studied the region for four decades, is known for his early role in establishing the global theory of plate tectonics. The authors compiled a catalog of all 383 known earthquakes from 1677 to 2007 in a 15,000-square-mile area around New York City. Coauthor John Armbruster estimated sizes and locations of dozens of events before 1930 by combing newspaper accounts and other records. The researchers say magnitude 5 quakes—strong enough to cause damage–occurred in 1737, 1783 and 1884. There was little settlement around to be hurt by the first two quakes, whose locations are vague due to a lack of good accounts; but the last, thought to be centered under the seabed somewhere between Brooklyn and Sandy Hook, toppled chimneys across the city and New Jersey, and panicked bathers at Coney Island. Based on this, the researchers say such quakes should be routinely expected, on average, about every 100 years. “Today, with so many more buildings and people, a magnitude 5 centered below the city would be extremely attention-getting,” said Armbruster. “We’d see billions in damage, with some brick buildings falling. People would probably be killed.” Starting in the early 1970s Lamont began collecting data on quakes from dozens of newly deployed seismometers; these have revealed further potential, including distinct zones where earthquakes concentrate, and where larger ones could come. The Lamont network, now led by coauthor Won-Young Kim, has located hundreds of small events, including a magnitude 3 every few years, which can be felt by people at the surface, but is unlikely to cause damage. These small quakes tend to cluster along a series of small, old faults in harder rocks across the region. Many of the faults were discovered decades ago when subways, water tunnels and other excavations intersected them, but conventional wisdom said they were inactive remnants of continental collisions and rifting hundreds of millions of years ago. The results clearly show that they are active, and quite capable of generating damaging quakes, said Sykes. One major previously known feature, the Ramapo Seismic Zone, runs from eastern Pennsylvania to the mid-Hudson Valley, passing within a mile or two northwest of Indian Point. The researchers found that this system is not so much a single fracture as a braid of smaller ones, where quakes emanate from a set of still ill-defined faults. East and south of the Ramapo zone—and possibly more significant in terms of hazard–is a set of nearly parallel northwest-southeast faults. These include Manhattan’s 125th Street fault, which seems to have generated two small 1981 quakes, and could have been the source of the big 1737 quake; the Dyckman Street fault, which carried a magnitude 2 in 1989; the Mosholu Parkway fault; and the Dobbs Ferry fault in suburban Westchester, which generated the largest recent shock, a surprising magnitude 4.1, in 1985. Fortunately, it did no damage. Given the pattern, Sykes says the big 1884 quake may have hit on a yet-undetected member of this parallel family further south. The researchers say that frequent small quakes occur in predictable ratios to larger ones, and so can be used to project a rough time scale for damaging events. Based on the lengths of the faults, the detected tremors, and calculations of how stresses build in the crust, the researchers say that magnitude 6 quakes, or even 7—respectively 10 and 100 times bigger than magnitude 5–are quite possible on the active faults they describe. They calculate that magnitude 6 quakes take place in the area about every 670 years, and sevens, every 3,400 years. The corresponding probabilities of occurrence in any 50-year period would be 7% and 1.5%. After less specific hints of these possibilities appeared in previous research, a 2003 analysis by The New York City Area Consortium for Earthquake Loss Mitigation put the cost of quakes this size in the metro New York area at $39 billion to $197 billion. A separate 2001 analysis for northern New Jersey’s Bergen County estimates that a magnitude 7 would destroy 14,000 buildings and damage 180,000 in that area alone. The researchers point out that no one knows when the last such events occurred, and say no one can predict when they next might come. “We need to step backward from the simple old model, where you worry about one large, obvious fault, like they do in California,” said coauthor Leonardo Seeber. “The problem here comes from many subtle faults. We now see there is earthquake activity on them. Each one is small, but when you add them up, they are probably more dangerous than we thought. We need to take a very close look.” Seeber says that because the faults are mostly invisible at the surface and move infrequently, a big quake could easily hit one not yet identified. “The probability is not zero, and the damage could be great,” he said. “It could be like something out of a Greek myth.” The researchers found concrete evidence for one significant previously unknown structure: an active seismic zone running at least 25 miles from Stamford, Conn., to the Hudson Valley town of Peekskill, N.Y., where it passes less than a mile north of the Indian Point nuclear power plant. The Stamford-Peekskill line stands out sharply on the researchers’ earthquake map, with small events clustered along its length, and to its immediate southwest. Just to the north, there are no quakes, indicating that it represents some kind of underground boundary. It is parallel to the other faults beginning at 125th Street, so the researchers believe it is a fault in the same family. Like the others, they say it is probably capable of producing at least a magnitude 6 quake. Furthermore, a mile or so on, it intersects the Ramapo seismic zone. Sykes said the existence of the Stamford-Peekskill line had been suggested before, because the Hudson takes a sudden unexplained bend just ot the north of Indian Point, and definite traces of an old fault can be along the north side of the bend. The seismic evidence confirms it, he said. “Indian Point is situated at the intersection of the two most striking linear features marking the seismicity and also in the midst of a large population that is at risk in case of an accident,” says the paper. “This is clearly one of the least favorable sites in our study area from an earthquake hazard and risk perspective.” The findings comes at a time when Entergy, the owner of Indian Point, is trying to relicense the two operating plants for an additional 20 years—a move being fought by surrounding communities and the New York State Attorney General. Last fall the attorney general, alerted to the then-unpublished Lamont data, told a Nuclear Regulatory Commission panel in a filing: “New data developed in the last 20 years disclose a substantially higher likelihood of significant earthquake activity in the vicinity of [Indian Point] that could exceed the earthquake design for the facility.” The state alleges that Entergy has not presented new data on earthquakes past 1979. However, in a little-noticed decision this July 31, the panel rejected the argument on procedural grounds. A source at the attorney general’s office said the state is considering its options. The characteristics of New York’s geology and human footprint may increase the problem. Unlike in California, many New York quakes occur near the surface—in the upper mile or so—and they occur not in the broken-up, more malleable formations common where quakes are frequent, but rather in the extremely hard, rigid rocks underlying Manhattan and much of the lower Hudson Valley. Such rocks can build large stresses, then suddenly and efficiently transmit energy over long distances. “It’s like putting a hard rock in a vise,” said Seeber. “Nothing happens for a while. Then it goes with a bang.” Earthquake-resistant building codes were not introduced to New York City until 1995, and are not in effect at all in many other communities. Sinuous skyscrapers and bridges might get by with minimal damage, said Sykes, but many older, unreinforced three- to six-story brick buildings could crumble. Art Lerner-Lam, associate director of Lamont for seismology, geology and tectonophysics, pointed out that the region’s major highways including the New York State Thruway, commuter and long-distance rail lines, and the main gas, oil and power transmission lines all cross the parallel active faults, making them particularly vulnerable to being cut. Lerner-Lam, who was not involved in the research, said that the identification of the seismic line near Indian Point “is a major substantiation of a feature that bears on the long-term earthquake risk of the northeastern United States.” He called for policymakers to develop more information on the region’s vulnerability, to take a closer look at land use and development, and to make investments to strengthen critical infrastructure. “This is a landmark study in many ways,” said Lerner-Lam. “It gives us the best possible evidence that we have an earthquake hazard here that should be a factor in any planning decision. It crystallizes the argument that this hazard is not random. There is a structure to the location and timing of the earthquakes. This enables us to contemplate risk in an entirely different way. And since we are able to do that, we should be required to do that.” New York Earthquake Briefs and Quotes: Existing U.S. Geological Survey seismic hazard maps show New York City as facing more hazard than many other eastern U.S. areas. Three areas are somewhat more active—northernmost New York State, New Hampshire and South Carolina—but they have much lower populations and fewer structures. The wider forces at work include pressure exerted from continuing expansion of the mid-Atlantic Ridge thousands of miles to the east; slow westward migration of the North American continent; and the area’s intricate labyrinth of old faults, sutures and zones of weakness caused by past collisions and rifting. Due to New York’s past history, population density and fragile, interdependent infrastructure, a 2001 analysis by the Federal Emergency Management Agency ranks it the 11th most at-risk U.S. city for earthquake damage. Among those ahead: Los Angeles, San Francisco, Seattle and Portland. Behind: Salt Lake City, Sacramento, Anchorage. New York’s first seismic station was set up at Fordham University in the 1920s. Lamont-Doherty Earth Observatory, in Palisades, N.Y., has operated stations since 1949, and now coordinates a network of about 40. Dozens of small quakes have been felt in the New York area. A Jan. 17, 2001 magnitude 2.4, centered in the Upper East Side—the first ever detected in Manhattan itself–may have originated on the 125th Street fault. Some people thought it was an explosion, but no one was harmed. The most recent felt quake, a magnitude 2.1 on July 28, 2008, was centered near Milford, N.J. Houses shook and a woman at St. Edward’s Church said she felt the building rise up under her feet—but no damage was done. Questions about the seismic safety of the Indian Point nuclear power plant, which lies amid a metropolitan area of more than 20 million people, were raised in previous scientific papers in 1978 and 1985. Because the hard rocks under much of New York can build up a lot strain before breaking, researchers believe that modest faults as short as 1 to 10 kilometers can cause magnitude 5 or 6 quakes. In general, magnitude 3 quakes occur about 10 times more often than magnitude fours; 100 times more than magnitude fives; and so on. This principle is called the Gutenberg-Richter relationship.

At this time, no satisfactory answers to these questions are available. A few years ago, rudimentary scenario studies were made for Boston and New York with limited scope and uncertain results. For most eastern cities, including Washington D.C., we know even less about the economic, societal and political impacts from significant earthquakes, whatever their rate of occurrence.
Is the public’s earthquake awareness (or lack thereof) controlled by perceived low Seismicity, SeismicHazard, or SeismicRisk? How do these three seismic features differ from, and relate to each other? In many portions of California, earthquake awareness is refreshed in a major way about once every decade (and in some places even more often) by virtually every person experiencing a damaging event. The occurrence of earthquakes of given magnitudes in time and space, not withstanding their effects, are the manifestations of seismicity. Ground shaking, faulting, landslides or soil liquefaction are the manifestations of seismic hazard. Damage to structures, and loss of life, limb, material assets, business and services are the manifestations of seismic risk. By sheer experience, California’s public understands fairly well these three interconnected manifestations of the earthquake phenomenon. This awareness is reflected in public policy, enforcement of seismic regulations, and preparedness in both the public and private sector. In the eastern U.S., the public and its decision makers generally do not understand them because of inexperience. Judging seismic risk by rates of seismicity alone (which are low in the east but high in the west) has undoubtedly contributed to the public’s tendency to belittle the seismic loss potential for eastern urban regions.
Let us compare two hypothetical locations, one in California and one in New York City. Assume the location in California does experience, on average, one M = 6 every 10 years, compared to New York once every 1,000 years. This implies a ratio of rates of seismicity of 100:1. Does that mean the ratio of expected losses (when annualized per year) is also 100:1? Most likely not. That ratio may be closer to 10:1, which seems to imply that taking our clues from seismicity alone may lead to an underestimation of the potential seismic risks in the east. Why should this be so?
To check the assertion, let us make a back-of-the-envelope estimate. The expected seismic risk for a given area is defined as the area-integrated product of: seismic hazard (expected shaking level), assets ($ and people), and the assets’ vulnerabilities (that is, their expected fractional loss given a certain hazard – say, shaking level). Thus, if we have a 100 times lower seismicity rate in New York compared to California, which at any given point from a given quake may yield a 2 times higher shaking level in New York compared to California because ground motions in the east are known to differ from those in the west; and if we have a 2 times higher asset density (a modest assumption for Manhattan!), and a 2 times higher vulnerability (again a modest assumption when considering the large stock of unreinforced masonry buildings and aged infrastructure in New York), then our California/New York ratio for annualized loss potential may be on the order of (100/(2x2x2)):1. That implies about a 12:1 risk ratio between the California and New York location, compared to a 100:1 ratio in seismicity rates.
From this example it appears that seismic awareness in the east may be more controlled by the rate of seismicity than by the less well understood risk potential. This misunderstanding is one of the reasons why earthquake awareness and preparedness in the densely populated east is so disproportionally low relative to its seismic loss potential. Rare but potentially catastrophic losses in the east compete in attention with more frequent moderate losses in the west. New York City is the paramount example of a low-probability, high-impact seismic risk, the sort of risk that is hard to insure against, or mobilize public action to reduce the risks.
There are basically two ways to respond. One is to do little and wait until one or more disastrous events occur. Then react to these – albeit disastrous – “windows of opportunity.” That is, pay after the unmitigated facts, rather than attempt to control their outcome. This is a high-stakes approach, considering the evolved state of the economy. The other approach is to invest in mitigation ahead of time, and use scientific knowledge and inference, education, technology transfer, and combine it with a mixture of regulatory and/or economic incentives to implement earthquake preparedness. The National Earthquake Hazard Reduction Program (NEHRP) has attempted the latter while much of the public tends to cling to the former of the two options. Realistic and reliable quantitative loss estimation techniques are essential to evaluate the relative merits of the two approaches.
The current efforts by the Federal Emergency Management Administration (FEMA) via the National Institute of Building Sciences (NIBS) to provide a standard methodology (RMS, 1994) and planning tools for making systematic, computerized loss estimates for annualized probabilistic calculations as well as for individual scenario events, is commendable. But these new tools provide only a shell with little regional data content. What is needed are the detailed data bases on inventory of buildings and lifelines with their locally specific seismic fragility properties.Similar data are needed for hospitals, shelters, firehouses, police stations and other emergency service providers. Moreover, the soil and rock conditions which control the shaking and soil liquefaction properties for any given event, need to be systematically compiled into Geographical Information System (GIS) data bases so they can be combined with the inventory of built assets for quantitative loss and impact estimates. Even under the best of conceivable funding conditions, it will take years before such data bases can be established so they will be sufficiently reliable and detailed to perform realistic and credible loss scenarios. Without such planning tools, society will remain in the dark as to what it may encounter from a future major eastern earthquake. Given these uncertainties, and despite them, both the public and private sector must develop at least some basic concepts for contingency plans. For instance, the New York City financial service industry, from banks to the stock and bond markets and beyond, ought to consider operational contingency planning, first in terms of strengthening their operational facilities, but also for temporary backup operations until operations in the designated facilities can return to some measure of normalcy. The Federal Reserve in its oversight function for this industry needs to take a hard look at this situation.
A society, whose economy depends increasingly so crucially on rapid exchange of vast quantities of information must become concerned with strengthening its communication facilities together with the facilities into which the information is channeled. In principle, the availability of satellite communication (especially if self-powered) with direct up and down links, provides here an opportunity that is potentially a great advantage over distributed buried networks. Distributed networks for transportation, power, gas, water, sewer and cabled communication will be expensive to harden (or restore after an event).
