Gov Brown signs bill to create Californian earthquake early warning system
Governor Jerry Brown signed Senate Bill 135 by Senator Alex Padilla (D-Pacoima), which requires that the Office of Emergency Services develop a comprehensive statewide earthquake early warning system to alert Californians in advance of dangerous shaking.
"I applaud Governor Brown for his vision and leadership. We live in earthquake country. He understands that when it comes to earthquakes in California, it is not a matter of if, but when,” said Senator Alex Padilla. “With Governor Brown’s signature, the process of developing a statewide earthquake early warning system has begun,” said Senator Alex Padilla.

What does this mean?
The law requires the Governor's Office of Emergency Services to
develop a comprehensive statewide earthquake early warning system
develop standards for the system and a mechanism to review compliance
identify funding for the system. Funding cannot come from the state General Fund.
From the SF Chronicle:
Development and operation of an early- warning system that would swiftly alert Californians when a damaging earthquake ruptures the ground anywhere in the state received unanimous approval by the state Legislature on Thursday.
The bill by Sen. Alex Padilla, D-Pacoima (Los Angeles County), is expected to be signed by Gov. Jerry Brown, legislative aides said.
Early versions of an earthquake early-warning system similar to one that is already operating in Japan have been under development and testing by scientists at UC Berkeley and the U.S. Geological Survey in Los Angeles for the past 15 years.

May 28, 2013: California State Senate passes earthquake early warning bill
The California State Senate approved Senate Bill 135 today, which would require the development of a comprehensive statewide earthquake early warning system in California.
"A fully developed earthquake early warning alert system would provide Californians critical seconds to take cover, assist loved ones, or pull over safely to the side of the road. It could allow time to stop a train and power down other critical infrastructure," said Senator Alex Padilla. "We all know a big quake will hit again in the future. We should be smart and use our science and technology to detect seismic activity and alert people in advance of destructive shaking," Padilla added.

Sounding the Alarm:
An early warning system would save thousands of lives when the next major earthquake hits. But will California find the money to implement it?

Azeen Ghorayshi, East Bay Express
At 2:46 p.m. on March 11, 2011, the Pacific Plate, just off Japan's northeast coast, suddenly thrust downward, unleashing a monstrous, 9.0-magnitude earthquake that rocked the country for the next six minutes. The massive Tohoku quake and resulting tsunami are believed to have killed at least 16,000 people and injured 6,000 more. Another 2,600 people are still missing and presumed dead. The quake was the most powerful to ever strike Japan, and was the fourth-largest ever recorded. It also was the first earthquake to be heard in outer space, and was the most expensive natural disaster in human history, generating $235 billion in total damage. But there was a silver lining, if you could call it that: Tohoku was also the first time that Japanese citizens were given the precious, if limited, gift of time.

"Seismologists don't like to make very many predictions," Allen said. "But I will make you one prediction, and that is that we will definitely build an early warning system in California. The only real question is whether it's immediately after the next big earthquake, or whether we actually manage to build it before."
UC Berkeley helping make BART quake-ready
Will Reisman, September 27, 2012, San Francisco Examiner
Operating a transit system in one of the most earthquake-prone areas in the country can be a perilous task. Knowing this, BART is taking no risks.
Working with UC Berkeley, the transit agency is the first in the nation to install an automated early warning earthquake system, which will provide BART with precious extra seconds to slow down or stop trains before a temblor hits the tracks.

US Scientists Testing Earthquake Early Warning
Alicia Chang, September 20, 2011, New York Times
Elizabeth Cochran was sitting in her office when her computer suddenly sounded an alarm.
Beep. Beep. Beep.
A map of California on her screen lit up with a red dot, signaling an earthquake had struck. A clock next to the map counted down the seconds until shock waves fanning out from the epicenter north of Los Angeles reached her location in Pasadena: 5-4-3-2-1.
Right on cue, Cochran felt her chair quiver ever so slightly from a magnitude-4.2 that rumbled through Southern California on Sept. 1.

Underground column of molten rock found at Yellowstone
September 8, 2010
by Lynne Peeples
A plume of molten rock rising from deep beneath Yellowstone National Park is probably what is fueling the region's volcanic activity, as well as tectonic plate oddities across the Pacific Northwest, new research suggests.
Building on a growing body of evidence, Mathias Obrebski of the University of California, Berkeley, and his colleagues created the most convincing picture to date of a Yellowstone mantle plume - one that extends from about 621 miles below the surface of the Earth.
If you thought the geysers and overblown threat of a supervolcanic eruption in Yellowstone National Park were dramatic, you ain't seen nothing: deep beneath Earth's surface, the hot spot that feeds the park has torn an entire tectonic plate in half.
The revelation comes from a new study in the journal Geophysical Research Letters that peered into the mantle beneath the Pacific Northwest to see what happens when ancient ocean crust from the Pacific Ocean runs headlong into a churning plume of ultra-hot mantle material.
It's been over 20 years since San Francisco endured a magnitude 7.1 tremblor, leaving many to ask if and when the next major quake will strike. TODAY's Lester Holt reports, then speaks with seismologist Richard Allen.
China's recent earthquake -- the fifth major global seismic event in four months -- is raising concern in quake-prone San Francisco that northern California may be next. Scientists are trying to prepare for ''the big one''. Ben Gruber reports.
Seismologists create and early warning system to alert Californians before an earthquake occurs

As it sweeps across America, the USArray network of seismometers is revealing an impressive but often befuddling subsurface menagerie of slabs, drips, and plumes. Clearly, the great blobs and chunks of rock rising, sinking, or just floating beneath the surface of the western United States bear some relation to overlying mountains, basins, and volcanic outpourings, but even the avalanche of new data can't always resolve exactly what the imaged features are or how they are shaping the surface. Already, the new images have added fuel to a long-running debate over the existence of mantle plumes, tall columns of hot rock rising thousands of kilometers from deep in the lower mantle like smoke from a stack.
Can we detect earthquakes before they strike? Richard Allen has created Elarms, a suite of algorithms designed to measure real time seismic data and then rapidly detect the initiation of an earthquake 5-10 seconds before it occurs-long enough to make a difference.
GARY ANDERSON was not around to see a backhoe tear up the buffalo grass at his ranch near Akron, Colorado. But he was watching a few weeks later when the technicians came to dump instruments and insulation into their 2-metre-deep hole.
What they left behind didn't look like much: an anonymous mound of dirt and, a few paces away, a spindly metal framework supporting a solar panel. All Anderson knew was that he was helping to host some kind of science experiment. It wouldn't be any trouble, he'd been told, and it wouldn't disturb the cattle. After a couple of years the people who installed it would come and take it away again.
He had in fact become part of what is probably the most ambitious seismological project ever conducted. Its name is USArray and its aim is to run what amounts to an ultrasound scan over the North American continent.
Do you want a 20-second warning?
If we adopted UC Berkeley seismologist Richard Allen's
breakthrough earthquake alarm system, your cell phone and laptop
could alert you to the Big One before the shaking begins.
Earthquake early warning around the world, but not yet in California
In December 2007 at the Fall Meeting of the American Geophysical Union a special session was convened on earthquake early warning around the world. While several countries - Japan, Taiwan, Turkey, Mexico and Romania - now have earthquake early warning, the seismic networks in California are still lacking for such systems. Here is some of the resulting coverage.

A few seconds warning could save lives, and all for just $2 or $3 per person
Can earthquakes be predicted? Northern California researchers are now identifying the slow-moving clues that may foreshadow violent quakes. Their work may provide even a few seconds of warning to open elevator doors, slow down trains or alert firefighters.
