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

We provide robust and real-time earthquake and hazard information on Northern California earthquakes, in collaboration with our partners.

We enable the broad consumption of earthquake information by the general public while educating and training students at all levels.
