Testing seismometers.

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.

Michael Manga Receives 2017 Distinguished Teaching Award

"My teaching and research are inseparable. I could not imagine doing one without the other. Teaching ensures that I deeply understand both core concepts and technical details – the foundations of research. To teach, in the classroom, laboratory, and field, I need to know current research priorities and key questions and keep up with new discoveries. This is especially true for introductory classes.”

Today in Earthquake History: Cape Mendocino 1992

Petrolia is - by any measure - the tiniest of hamlets in California.

Your legs may feel unsteady, you may even be thrown off balance and fall, if the ground motion is strong enough. The experience is certainly unnerving and it may even cause you to panic...

The Quake of the Kalahari

An extremely unusual earthquake occurred in southern Africa Monday evening around 8 pm (local time). The tremor with a magnitude of at least 6.5 struck a very remote region of the Kalahari desert in Botswana, as indicated by the yellow dot in the center of the Google Earth map. The seismic waves were felt in the country's capital Gabarone about 150 miles from the epicenter...
