The vault at our seismic station GASB.

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.

Tiny Changes Make a Great New Tool

Seismic waves, it is often said, are the messengers which earthquakes send around the world. Generated at or very near a temblor's source, they contain information about the goings-on during an earthquake rupture. If the quake from which they originate is strong enough, seismic waves may also bring with them destruction and mayhem when they hit populated areas...

Research Update: Aseismic Creep on the Mendocino Fault Zone

Continuing their research on repeating earthquakes at the Mendocino Triple Junction, the place where the Pacific, North American, and Gorda plates collide, BSL researchers Kathryn Materna, Taka'aki Taira, and Roland Bürgmann have further characterized the "creep" on the Mendocino Fault Zone...

A Shock Without Aftershocks

When the blogger called the big magnitude 8.1 earthquake, which occurred off the coast of southern Mexico on September 8th, a rare event, he couldn't have known that our neighbor to the south would be shaken by an even stranger temblor 12 days later...
