The HayWired earthquake scenario, led by the U. ForewordThe Great San Francisco earthquake magnitude 7.
Since Loma Prieta, bay-region communities, governments, and utilities have invested tens of billions of With innovations, fresh data, and lessons learned from recent earthquakes, scientists have developed a new earthquake forecast model for California, a region under constant threat from potentially damaging events. The primary goal of U. Geological Survey USGS Natural Hazards Response is to ensure that the disaster response community has access to timely, accurate, and relevant geospatial products, imagery, and services during and after an emergency event.
On November 13, , over 5 million Southern Californians pretended that the magnitude This is the initial publication of the results of a cooperative project to examine the implications of a major earthquake in southern California. Its results will be used as the basis of an emergency response and preparedness Earthquakes are one of the most costly natural hazards faced by the Nation, posing a significant risk to 75 million Americans in 39 States.
The risks that earthquakes pose to society, including death, injury, and economic loss, can be greatly reduced by 1 better planning, construction, and mitigation practices before earthquakes happen, and This handbook provides information about the threat posed by earthquakes in the San Francisco Bay region and explains how you can prepare for, survive, and recover from these inevitable events. If you live or work in the region, you need to know why you should be concerned with earthquakes, what you can expect during and after a quake, and what USGS collaborates with key academic, state, local, and industry partners to provide a new look at what could happen during a major earthquake in the San Francisco Bay Area.
Early on the morning of August 24, , Loren Turner was awoken by clattering window blinds, a moving bed, and the sound of water splashing out of his backyard pool. A new report issued by the American Red Cross and the U. Geological Survey documents the Chilean response and recovery efforts following the Feb. Twenty years after the Loma Prieta earthquake caused loss of life and widespread property damage, advances in science, technology and engineering have the San Francisco Bay Area better prepared for the next big earthquake.
When the Loma Prieta quake hit just after 5 p. October 17, — 20 years ago Saturday — the digital age was in its infancy. On October 17, minutes before the scheduled start of the third game of the World Series in San Francisco, a magnitude 6. Ken Hudnut in a new video interview. The San Andreas and neighboring faults near Los Angeles interact in surprising, and, in some cases, potentially dangerous ways, according to an article by U. Geological Survey scientists to be published in the Dec.
The researchers reviewed lessons from past earthquakes and combined that with powerful computer modeling to reach their conclusions. The Gold Rush and the Earthquake: How they combined to create the breakthrough discovery of modern seismic science. Three-dimensional perspective view of the likelihood that each region of California will experience a magnitude 6. The purpose of this map is to show the location of and evidence for recent movement on active fault traces within the Hayward Fault Zone, California.
The mapped traces represent the integration of the following three different types of data: 1 geomorphic expression, 2 creep aseismic fault slip ,and 3 trench exposures. A simulation of the ShakeOut Scenario as described at shakeout.
The adult males congregate on mangrove leaves where they display synchronous, flashing light sequences to attract females. As the bats fly in for a drink, the pollen from the flower sticks to their bodies. The net result is that companies tend to overinvest in the past and underinvest in the future. Through the past two decades, respect for the courts, the schools, the press, Congress, organized religion, Big Business, and virtually every other institution in modern life has plummeted. What is seismic hazard? Hundreds of thousands of livestock were introduced to pine forests and grasslands in western states 40 , 42 in the late s.

For locations outside the United States for which seismic design is required for military facilities, there exists a standard based on probabilistic spectral ordinates in the manner of the International Building Code and are declared to reflect the version of How are engineers working to make roads and buildings safer?
Earthquake engineers are working to make roads and buildings safer in the event of a major earthquakes. This includes both improving the design of new buildings and bridges as well as strengthening older units to incorporate the latest advances in seismic and structural engineering.
The Federal Emergency Management Agency plays a central role in What is the USGS doing to mitigate and respond to earthquake hazards? The U.
Geological Survey performs the following functions related to earthquake hazard mitigation: Receives, analyzes, maintains, and distributes data on earthquake activity worldwide. These stations, located throughout the world Can the National Seismic Hazard Maps be used as an earthquake forecast tool for the near future? Not really. This web site is designed to display the probability of different sources that might occur in a several-year to several-decade period. The model bases all probability estimates on mean rate of earthquakes over long periods.
As you shorten the time window, you should expect greater and greater fluctuations in what may be observed from What is the probability that an earthquake is a foreshock to a larger earthquake? In California, about half of the biggest earthquakes were preceded by foreshocks; Are earthquake probabilities or forecasts the same as prediction?
Probabilities and forecasts are rather like climate probabilities and weather forecasts, while predictions are more like statements of when, where, and how large, which is not yet possible for earthquakes. Probabilities describe the long-term chances that an earthquake of a certain magnitude will happen during a time window.
Most earthquake How do I decide whether or not to get earthquake insurance? You should consider the following factors when deciding whether or not to get earthquake insurance: proximity to active earthquake faults seismic history of the region frequency of earthquakes time since last earthquake building construction type of building and foundation architectural layout materials used quality of workmanship extent to How do earthquakes affect buildings?
Ground shaking is the primary cause of earthquake damage to man-made structures. Many factors influence the strength of earthquake shaking at a site including the earthquake's magnitude, the site's proximity to the fault, the local geology, and the soil type. More than structures throughout the United States have been outfitted with seismic What is the likelihood of a large earthquake at location X? Is it safe to go to X since they've been having a lot of earthquakes lately? The calculation is based on the latest available information from seismic hazard data.

Published maps will only provide generalized, uninterpreted information about specific areas. As a country, America has been at war nonstop for the past 13 years. As a public, it has not. A total of about 2. The difference between the earlier America that knew its military and the modern America that gazes admiringly at its heroes shows up sharply in changes in popular and media culture.
From Mister Roberts to South Pacific to Catch , from The Caine Mutiny to The Naked and the Dead to From Here to Eternity , American popular and high culture treated our last mass-mobilization war as an effort deserving deep respect and pride, but not above criticism and lampooning. The collective achievement of the military was heroic, but its members and leaders were still real people, with all the foibles of real life.
A decade after that war ended, the most popular military-themed TV program was The Phil Silvers Show , about a con man in uniform named Sgt. American culture was sufficiently at ease with the military to make fun of it, a stance now hard to imagine outside the military itself. As I point out whenever discussing this topic, I was eligible for the draft at the time, was one of those protesting the war, and at age 20 legally but intentionally failed my draft medical exam.
What we think of as the classic run of Vietnam films did not begin until the end of the s, with The Deer Hunter and Apocalypse Now. Bilko model, again suggesting a culture close enough to its military to put up with, and enjoy, jokes about it.
The pop-culture references to the people fighting our ongoing wars emphasize their suffering and stoicism, or the long-term personal damage they may endure. Some emphasize high-stakes action, from the fictionalized 24 to the meant-to-be-true Zero Dark Thirty.

Often they portray military and intelligence officials as brave and daring. Last year, the writer Rebecca Frankel published War Dogs , a study of the dog-and-handler teams that had played a large part in the U. Part of the reason she chose the topic, she told me, was that dogs were one of the few common points of reference between the military and the larger public. But … dogs! For two decades after World War II, the standing force remained so large, and the Depression-era birth cohorts were so small, that most Americans had a direct military connection.
Among older Baby Boomers, those born before , at least three-quarters have had an immediate family member—sibling, parent, spouse, child—who served in uniform. Of Americans born since , the Millennials, about one in three is closely related to anyone with military experience.
