December 12 '07: Seismologists in California are testing new technologies and systems designed to detect and predict earthquakes, the San Francisco Chronicle reported. Testing of the new lattice-work systems will last into 2009, but more monitoring stations are needed, scientists said. If effective the new technology "being tested could provide seconds or even minutes of early notification that a dangerous quake has struck."
Earthquake Alarm Systems (Elarms) is currently being tested by the California Integrated Seismic Network. Specifically, Elarms "links seismometer arrays - from California's northernmost regions, where the San Andreas Fault zone makes a right-angle turn beneath the Pacific, to the southernmost part of the state, where the quake danger crosses the border into Mexico," the Chronicle reported.Richard Allan from the University of California's Seismological Laboratory told the Chronicle if the Elarms system works it will require about double the amount of seismic sensors in the state with a total cost of $30 million. Additionally, seismic stations in San Francisco and Los Angeles would need upgrades as well.
