1906-type earthquake could be devastating

Mar 17 ,Space & Earth science


If a similar magnitude 7.9 earthquake hit San Francisco as it did in 1906, the damage would be on the magnitude of hurricanes Katrina and Rita.

"There will be mass casualties. There will be losses of businesses and institutions," Rich Eisner, coastal region chief for the California Office of Emergency Services, said in a briefing Thursday for East Bay emergency managers. "Nobody will be safe."

Eisner said damages from such a earthquake are estimated at $122 billion, close to the costs of hurricanes Katrina and Rita that his the U.S. Gulf Coast last year, the Oakland (Calif.) Tribune reported Friday.

A high magnitude earthquake would effectively make the Bay Area an island, since all highways and bridges would likely be impassable, its hospitals overwhelmed and outside help beyond reach because of fires, Eisner said.

"It is comparable to the worst natural disaster in American history," he said.

Earthquakes may endanger New York more than formerly believed
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.

Supercomputer Unleashes Virtual 9.0 Megaquake in Pacific Northwest
On January 26, 1700, at about 9 p.m. local time, the Juan de Fuca plate beneath the ocean in the Pacific Northwest suddenly moved, slipping some 60 feet eastward beneath the North American plate in a monster quake of approximately magnitude 9, setting in motion large tsunamis that struck the coast of North America and traveled to the shores of Japan.
Status quo of the tsunami early warning system for the Indian Ocean
The German-Indonesian Tsunami Early Warning System for the Indian Ocean (GITEWS) runs on track. Main milestones like the development of the automatic data processing software SeisComP3, as well as the underwater communication for the transmission of the pressure data from the ocean floor to a warning centre are already finalised. Furthermore the calculations of the ocean modelling including the source modelling were completed and are available in a data base so that the system can be set into operation at the end of 2008. This positive conclusion is drawn by the GITEWS consortium consisting of different German geo and marine scientists on the occasion of the third anniversary of the tsunami catastrophe on December 26, 2004.
Researchers Announce New Way to Assess How Buildings Would Stand Up in Big Quakes
How much damage will certain steel-frame, earthquake-resistant buildings located in Southern California sustain when a large temblor strikes? It's a complicated, multifaceted question, and researchers from the California Institute of Technology, the University of California, Santa Barbara, and the University of Pau, France, have answered it with unprecedented specificity using a new modeling protocol.
Earthquakes Kill Nearly 90,000 In 2005
Although there were fewer deaths worldwide in 2005 due to earthquakes, more than 89,353 casualties were reported, according to the U.S. Geological Survey (USGS) and confirmed by the United Nations Office for Coordination of Humanitarian Affairs (OCHA). Nearly all of the fatalities for the year, more than 87,000, occurred when a magnitude 7.6 hit Pakistan on Oct. 8.
New system for earthquake early warning
A University of California, Berkeley, seismologist has discovered a way to provide seconds to tens of seconds of advance warning about impending ground shaking from an earthquake.
Major losses projected for earthquake on little-known fault under Los Angeles
A new estimate of the effect of an earthquake along the Puente Hills fault shows that damage could occur on an unprecedented scale.
An earthquake of magnitude 7.2 to 7.5 would result in 3,000 to 18,000 deaths, 142,000 to 735,000 displaced households, and up to $250 billion in property damage, according to research by the U.S. Geological Survey and the Southern California Earthquake Center at the University of Southern California. The disaster would be the costliest in U.S. history.
