Earthquake and Hazard Resources

The Berkeley Seismological Laboratory (BSL) and the USGS are responsible for reporting on Northern California earthquakes as part of the statewide monitoring effort known as the California Integrated Seismic Network.

Map of Earthquakes

Explore our real-time, clickable earthquake map with the last seven days of earthquake activity, centered on the state of California.

Seismograms

Current Berkeley Digital Seismic Network Seismograms. Take a quick look at the last 24 hours of data from our stations throughout Northern California.

ShakeMaps

ShakeMaps are automatically generated maps of near-real-time ground motion following significant earthquakes. Data from the BSL and other regional seismic networks are used to create these maps, which are distributed to federal, state, and local agencies for use in response and recovery.

Hayward Fault Map

The Hayward Fault

The Hayward Fault passes through UC Berkeley. Check out our web pages on the hazard in our own backyard.

Great CA ShakeOut banner

Great California ShakeOut

The Great California ShakeOut is a statewide earthquake drill to aid families and organizations in becoming prepared for the next big quake.

Earthquake Catalog

Search for earthquakes in our Northern California and Global catalogs, hosted at our Northern California Earthquake Data Center.

Bloom

In Bloom, by Ken Goldberg, Sanjay Krishnan, Fernanda Viagas, and Martin Wattenberg, ground motion along the Hayward Fault in California is detected by a seismograph, transmitted continuously via the Internet and processed to generate an evolving field of circular blooms.

Get Prepared

Learn the seven steps to earthquake safety and follow some solid earthquake preparedness links.

Did You Feel It?

Report your shaking experience to the USGS with this online form.

Earthquake Notification Service

From the USGS: Sign up for email or text message notification about earthquakes in California and/or the World Earthquake Notification Service. This free service alerts you when earthquakes happen in you area.
