America Overdue For The Sixth Seal (Revelation 6:12)

New Study: America Overdue For Major Earthquake … In States You Didn’t Suspect

New York Destroyed
Written by: Daniel Jennings Current Events
Most Americans have a reasonable chance of experiencing a destructive earthquake within the next 50 years, the US Geological Survey (USGS) has concluded.

The survey’s new National Seismic Hazard Map show that the risk of earthquakes in parts of the country — such as the Midwest, Oregon and the Rocky Mountains — is far higher than previously thought. All total, Americans in one-third of the country saw their risk for an earthquake increase.
“I worry that we will wake up one morning and see earthquake damage in our country that is as bad as that has occurred in some developing nations that have experienced large earthquakes,” Carl Hedde, a risk management expert at insurer Munich Reinsurance America, said of the map in The Wall Street Journal. “Beyond building collapse, a large amount of our infrastructure could be immediately damaged. Our roads, bridges and energy transmission systems can be severely impacted.”
Among the findings:

  • The earthquake danger in parts of Missouri, Arkansas, Tennessee, Illinois and South Carolina is as high as that in Los Angeles.
  • 42 of the 50 states have a reasonable chance of experiencing a damaging earthquake in the next 50 years.
  • Parts of 16 states have the highest risk of a quake: Alaska, Hawaii, California, Oregon, Washington, Nevada, Utah, Idaho, Montana, Wyoming, Missouri, Arkansas, Tennessee, Illinois, Kentucky and South Carolina

“We know the hazard has increased for small and moderate size earthquakes,” USGS scientist William Ellsworth told The Journal. “We don’t know as well how much the hazard has increased for large earthquakes. Our suspicion is it has but we are working on understanding this.”
Frightening Results From New Study
The USGS used new computer modeling technology and data collected from recent quakes such as the one that struck Washington, D.C. in 2011 to produce the new maps. The maps show that many Americans who thought they were safe from earthquakes are not.

Some of the survey’s other disturbing findings include:

    • The earthquake danger in Oklahoma, Alabama, Colorado, Georgia, Indiana, Michigan, Virginia, New York and parts of New England is higher than previously thought.
    • Some major metropolitan areas, including Memphis, Salt Lake City, Seattle, St. Louis and Charleston, have a higher risk of earthquakes than previously thought. One of the nation’s most dangerous faults, the New Madrid fault, runs right through St. Louis and Missouri. It is the nation’s second most active fault. On Dec. 16, 1811, the New Madrid Fault was the site of the most powerful series of earthquakes in American history.

“Obviously the building codes throughout the central U.S. do not generally take earthquake risk or the risk of a large earthquake into account,” USGS Seismologist Elizabeth Cochran told The Journal. Her take: Earthquake damage in the central US could be far greater than in places like California, because structures in some locations are not built to withstand quakes.
Others agree.
“Earthquakes are quite rare in many places but when they happen they cause very intense damage because people have not prepared,” Mark Petersen, the project chief for the USGS’s National Seismic Hazard Map, told The Journal.
This new map should be a wakeup call for Americans.

The Coney Island earthquake of 1884

New York City isn’t immune to earthquakes; a couple of small tremors measuring about 2.5 on the Richter scale even struck back in 2001 and 2002.
But on August 10, 1884, a more powerful earthquake hit. Estimated from 4.9 to 5.5 in magnitude, the tremor made houses shake, chimneys fall, and residents wonder what the heck was going on, according to a New York Times article two days later.
The quake was subsequently thought to have been centered off Far Rockaway or Coney Island.
It wasn’t the first moderate quake, and it won’t be the last. In a 2008 Columbia University study, seismologists reported that the city is crisscrossed with several fault lines, one along 125th Street. 
With that in mind, New Yorkers should expect a 5.0 or higher earthquake centered here every 100 years, the seismologists say.
Translation: We’re about 30 years overdue. Lucky for us the city adopted earthquake-resistant building codes in 1995.

The current efforts in the eastern U.S., including New York City, to start the enforcement of seismic building codes for new constructions are important first steps in the right direction. Similarly, the emerging efforts to include seismic rehabilitation strategies in the generally needed overhaul of the cities’ aged infrastructures such as bridges, water, sewer, power and transportation is commendable and needs to be pursued with diligence and persistence. But at the current pace of new construction replacing older buildings and lifelines, it will take many decades or a century before a major fraction of the stock of built assets will become seismically more resilient than the current inventory is. For some time, this leaves society exposed to very high seismic risks. The only consolation is that seismicity on average is low, and, hence with some luck, the earthquakes will not outpace any ongoing efforts to make eastern cities more earthquake resilient gradually. Nevertheless, M = 5 to M = 6 earthquakes at distances of tens of km must be considered a credible risk at almost any time for cities like Boston, New York or Philadelphia. M = 7 events, while possible, are much less likely; and in many respects, even if building codes will have affected the resilience of a future improved building stock, M = 7 events would cause virtually unmanageable situations. Given these bleak prospects, it will be necessary to focus on crucial elements such as maintaining access to cities by strengthening critical bridges, improving the structural and nonstructural performance of hospitals, and having a nationally supported plan how to assist a devastated region in case of a truly severe earthquake. No realistic and coordinated planning of this sort exists at this time for most eastern cities.
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).
In all future instances of major capital spending on buildings and urban infrastructures, the incorporation of seismically resilient design principles at all stages of realization will be the most effective way to reduce society’s exposure to high seismic risks. To achieve this, all levels of government need to utilize legislative and regulatory options; insurance industries need to build economic incentives for seismic safety features into their insurance policy offerings; and the private sector, through trade and professional organizations’ planning efforts, needs to develop a healthy self-protective stand. Also, the insurance industry needs to invest more aggressively into broadly based research activities with the objective to quantify the seismic hazards, the exposed assets and their seismic fragilities much more accurately than currently possible. Only together these combined measures may first help to quantify and then reduce our currently untenably large seismic risk exposures in the virtually unprepared eastern cities. Given the low-probability/high-impact situation in this part of the country, seismic safety planning needs to be woven into both the regular capital spending and daily operational procedures. Without it we must be prepared to see little progress. Unless we succeed to build seismic safety considerations into everyday decision making as a normal procedure of doing business, society will lose the race against the unstoppable forces of nature. While we never can entirely win this race, we can succeed in converting unmitigated catastrophes into manageable disasters, or better, tolerable natural events.

If today a magnitude 6 earthquake were to occur centered on New York City, what would its effects be? Will the loss be 10 or 100 billion dollars? Will there be 10 or 10,000 fatalities? Will there be 1,000 or 100,000 homeless needing shelter? Can government function, provide assistance, and maintain order? 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.
Why do we know so little about such vital public issues? Because the public has been lulled into believing that seriously damaging quakes are so unlikely in the east that in essence we do not need to consider them. We shall examine the validity of this widely held opinion.
Is the public’s earthquake awareness (or lack thereof) controlled by perceived low Seismicity, Seismic Hazard, or Seismic Risk? 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.
This paper tries to bring into focus some of the seismological factors which are but one set of variables one needs for quantifying the earthquake loss potential in eastern U.S. urban regions. We use local and global analogs for illustrating possible scenario events in terms of risk. We also highlight some of the few local steps that have been undertaken towards mitigating against the eastern earthquake threat; and discuss priorities for future actions.

The Risk Of A New York Earthquake (Revelation 6:12)

Could a major earthquake shake the Big Apple to its core?If the past is any indication, the answer is yes, says John Armbruster, a seismologist at Columbia University’s Lamont-Doherty Earth Observatory.Based on historical precedent, Armbruster says the New York City metro area is susceptible to an earthquake of at least a magnitude of 5.0 once a century.Lynn Skyes, lead author of a recent study by seismologists at the Lamont-Doherty Earth Observatory adds that a magnitude-6 quake hits the area about every 670 years, and magnitude-7 every 3,400 years.A 5.2-magnitude quake shook New York City in 1737 and another of the same severity hit in 1884. Tremors were felt from Maine to Virginia.
There are several fault lines in the metro area, including one along Manhattan’s 125th St. – which may have generated two small tremors in 1981 and may have been the source of the major 1737 earthquake, says Armbruster. There’s another fault line on Dyckman St. and one in Dobbs Ferry in nearby Westchester County.
“The problem here comes from many subtle faults,” explained Skyes after the study was published. “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.”
“While uncommon, the earthquake hazard of the New York City metropolitan area has been assessed as moderate,” the New York City Area Consortium for Earthquake Loss Mitigation writes on its website. “Considering population density and the condition of the region’s infrastructure and building stock, it is clear that even a moderate earthquake would have considerable consequences in terms of public safety and economic impact.”
Armbruster says a 5.0-magnitude earthquake today likely would result in casualties and hundreds of millions of dollars in damage. “I would expect some people to be killed,” he notes. “Enough chimneys, facades on buildings would fall and someone would be underneath.”
The scope and scale of damage would multiply exponentially with each additional tick on the Richter scale.
“Will there be one in my lifetime or your lifetime? I don’t know. But this is the longest period we’ve gone without one.”
