The USGS has determined there is a 72 percent of at least one earthquake of magnitude 6.7 or greater striking somewhere in the Bay Area in the next 30 years.
The Association of Bay Area Governments wants to help you prepare. An online tool from ABAG is available to help residents identify potential earthquake-related damage to their homes and provides information on how to gird against the next big temblor.
It’s the continual movement of the Earth’s plates against each other that causes energy to build. When the plates slip, energy is released and earthquakes result. In the Bay Area’s case, it’s the Pacific Plate moving northwest past the North American Plate that puts pressure along the faults in the region.
