You don't see earthquakes coming as you would with, say, a hurricane. But that may soon change with recent advancements to a "groundbreaking" early warning system developed, in part, by Google's philanthropic arm.
Earlier this year, a consortium of researchers from UC Berkeley, the USGS, and other universities began testing the prototype system. It relies on a network of seismological sensors embedded throughout the West Coast -- the same already used to monitor quake activity -- to detect P-waves. P-waves are the initial tremors, often very minute, that precede the destructive S-waves. Upon any detection of a P-wave, the new system would immediately notify the public of an impending quake. This will provide people, hospitals, and utilities precious seconds and minutes to prepare.
But how does the word get out? That's where Google comes in. Currently, TV and radio announcements are the norm with a few cellular carriers providing alerts as well. Now, Google and several other companies, including Deutsche Telekom's Silicon Valley Innovation centre are looking into how to instantly disseminate the warnings on multiple platforms such as computers, mobile phone alerts, and community alert systems.
The project has been developed in conjunction with Google.org and just been awarded a $US6 million grant from the Gordon and Betty Moore Foundation in Palo Alto that "is going to allow us to make this test system much more robust," said Richard Allen, director of the UC Berkeley Seismological Laboratory. A full-scale test is expected within three years -- assuming they can find the $US150 million needed to do so -- and have a functional system ready within five. [Contra Costa Times]
