Developed by the leading seismologists, the ShakeAlert system uses signals from more than 700 seismometers installed across the state by USGS, Cal OES, University of California Berkeley, and the California Institute of Technology. A few seconds of warning can make a difference in giving you time to drop, cover, and hold on before the shaking arrives.
It uses this technology to share a fast, accurate view of the impacted area on Google Search. When you look up “earthquake” or “earthquake near me,” you’ll find relevant results for your area, along with helpful resources on what to do after an earthquake.
