Scientists at UC Berkeley released a video Sunday morning showing an early warning system they are working on sent a 10-second alert for the 6.1 earthquake that hit near Napa.
The ShakeAlert earthquake early warning project is a demonstration system at the UC Berkeley Seismological Laboratory.
Sunday’s quake was centered in American Canyon in Napa County. There were reports of widespread power outages and water main breaks, most of the injuries were in and around Napa and appear to be minor.
UC Berkeley’s early warning system has been used to motivate state lawmakers to fund the project to provide warning to the public.
According to the LA Times, the statewide system could give a 40-50 second warning before the “big one”.
