The Berkeley Seismological Laboratory conducts essential research on earthquakes and solid earth processes while collecting and delivering high quality geophysical data.

We provide robust earthquake and hazard information including real-time alerts to the public, in collaboration with our partners.

We enable the broad consumption of earthquake information by everyone while educating and training students at all levels and from all backgrounds.
