Third grade students at William L. Cobb Elementary School take cover under desks as they participate in the "Great California ShakeOut" earthquake drill on October 20, 2011 in San Francisco, California.
In case of an earthquake we know the the drill: Drop.Cover.Hold On. But that’s only once we feel the earth start to tremble. What if we had a warning system that allows us to be ready to respond and find a safe place to hold on? California will be the first state to have an earthquake early warning system thanks to a bill signed by Governor Brown in late September.
The bill directs the state’s Office of Emergency Services to identify sources of funding by 2016. The statewide system would cost $80 million to build. Scientists have been running successful test versions of the system for two years.
So how would the early warning system inform residents there is an earthquake? How much of the California system is based on earthquake early warning systems we see in other countries?
