With all of the news about probable seismic activity on the Hayward fault, there has been quite a bit of interest recently in seismology of the East Bay. There are quite a few seismological resources available for areas all around the globe in the Earth Sciences and Map Library.

The UC Berkeley Seismological Lab also has many resources and programs concerned with earthquakes in the Bay Area and beyond.

Professor Brimhall's class website for Field Geology and Digital Mapping (EPS 101/271) has some interesting information regarding geological mapping with computers.

Here's a list of just a few sites available online:

The Geology of Bear Territory: A Tour of the UC Berkeley Campus (UC Berkeley Seismological Lab)

This tour includes directions and information regarding geologically interesting places on Berkeley's campus. Also includes links to other tours from California State University East Bay and the USGS.

The Hayward Fault (UC Berkeley Seismological Lab)

A great resource for all things Hayward fault. Includes a description of the fault's seismicity and earthquake potential, a section on hazards and preparedness, and links for further information.

USGS (in cooperation with the California Geological Survey)

This site has quite a bit of information regarding the Hayward fault and includes quite a few digital maps and information regarding the many faults in the San Francisco Bay Area.
