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.

A Slow Emergency and a Sudden Slump

The current eruption of Kilauea volcano on Hawaii's Big Island is accompanied by thousands of earthquakes. Most of them have magnitudes below 2.5, but some of them are significantly bigger. However, not all of them are created equal...

Quakes on Mars?

When engineers from the Berkeley Seismological Laboratory set out to install a new seismic monitoring station in Northern California, their task is relatively straightforward. Once a landowner has agreed to support Earth science by hosting a new station, a suitable location needs to be found on the land in question...

Does the East Bay Swarm Again?

In this blog, we have often reported about unique earthquake swarms, which happen in the San Ramon Valley in the eastern San Francisco Bay Area west of Mt. Diablo. In fact, the very first entry into this blog almost ten years ago was about a magnitude 4 temblor under Alamo and its relationship to these earthquake swarms...
