California Earthquake Early Warning System Gets an Early Test
California’s earthquake early warning system may have taken a step forward this week when officials conducted a test in downtown Oakland.
The USGS, in partnership with the California Governor’s Office of Emergency Services (Cal OES), the city of Oakland and Alameda County, issued Wireless Emergency Alerts (WEA) soliciting a response to a survey to about 40,000 people in a 60-acre block. It went well, but not perfectly.
