Earthquake and Hazard Resources
The Berkeley Seismological Laboratory (BSL) provides robust and reliable data, both in real time and from our archives, that give the public as well as collaborators (such as the US Geological Survey and CalOES) information they need to better deal with, and prepare for, hazardous situations. In addition, the USGS and the BSL are responsible for reporting on Northern California earthquakes as part of the statewide monitoring effort known as the California Integrated Seismic Network.
Our homepage displays a real-time, clickable earthquake map with the last seven days of earthquake activity, centered on the state of California.
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.
