The U.S. Geological Survey and five universities, including UC Berkeley and Stanford, are enlisting the help of “citizen seismologists” to host earthquake sensors in their homes as part of a new Quake Catcher Network. The first 200 to sign up will have sensors installed starting July 9.

Large 2012 earthquake triggered temblors worldwide for nearly a week
September 26, 2012:
This year’s largest earthquake, a magnitude 8.6 temblor on April 11 centered in the East Indian Ocean off Sumatra, did little damage, but it triggered quakes around the world for at least a week, according to a new analysis by UC Berkeley and USGS seismologists. Some large quakes apparently can prime other, very distant faults to break later, says study co-author Roland Burgmann.
Gordon and Betty Moore Foundation awards $6 million for earthquake early warning research
November 29, 2011:
UC Berkeley, Caltech and the University of Washington will each receive $2 million from the Gordon and Betty Moore Foundation to conduct research on an earthquake early warning system that seismologists hope to create along the Pacific Coast.
Third modest quake within week sends message: Be prepared!
October 27, 2011:
A 3.6 magnitude earthquake this morning (Thursday, Oct. 27) – the third small quake in a week on the Hayward Fault near UC Berkeley – sent a message to all East Bay residents: Be prepared!
Seismologists urge creation of earthquake early warning system along Pacific Coast
April 5, 2011:
Following a closed-door summit at UC Berkeley, leading West Coast seismologists recommended in a news conference today (Tuesday, April 5) the establishment of an earthquake early warning system in California, Oregon and Washington.
Project will monitor tremor activity beneath San Andreas Fault
December 9, 2010:
The Gordon and Betty Moore Foundation has donated $1.2 million to the Berkeley Seismological Laboratory to install a small network of earthquake sensors around the San Andreas Fault at Cholame to monitor faint tremors that have been discovered in the area.
High pressure experiments reproduce mineral structures 1,800 miles deep
September 23, 2010:
UC Berkeley and Yale University scientists have recreated the tremendous pressures and high temperatures deep in the Earth to resolve a long-standing puzzle: why some seismic waves travel faster than others through the boundary between the solid mantle and fluid outer core.
North American continent is a layer cake, scientists discover
August 25, 2010:
The North American continent is not one thick, rigid slab, but a layer cake of ancient, 3 billion-year-old rock on top of much newer material probably less than 1 billion years old, according to a new study by UC Berkeley seismologists. The new findings by Barbara Romanowicz and Huaiyu Yuan also indicate that the continent grew by addition of rock from subducting ocean floor, not by mantle plume upwelling from below.
