Last week’s 6.0 earthquake near Napa was a strong reminder that California is one of the most seismically active regions in the world. The Napa quake caused serious damage and hundreds of local residents had to seek treatment at area hospitals. Napa was hit hard, but it could have been a lot worse.
One way to reduce injuries is to provide advance warning of an earthquake. California presently has a demonstration earthquake early-warning system called the California Integrated Seismic Network, which functions as a research tool. We should expand this system and provide earthquake warnings to all Californians. A fully developed system would process data from a statewide network of sensors, detect the strength and the progression of an earthquake, alert the public within seconds and provide tens of seconds’ advanced warning before damaging ground shaking is felt.
