What fault is San Ramon on?

Calaveras Fault

The geologic structure in the San Ramon Valley is very complex. The main fault is the Calaveras Fault, which splits from the San Andreas Fault near Pinnacles National Monument 100 miles further south.

Is the Calaveras Fault fully locked?

The central and southern segments of the Calaveras fault are predominantly creeping, whereas the Hayward, Northern Calaveras, and Maacama faults are partly locked and, along with the Rodgers Creek and San Andreas, have high potential for major earthquakes.
