According to 2010 census data, Alameda County is made up of 739.02 square miles of land, which equates to 1,666,753 people per square mile. The region is part of the San Francisco Bay Area (which borders the county on the west) and stretches along most of East Bay. Berkeley Hills form a section of the northeastern boundary and continues into the center of the county. A coastal plain several miles wide follows along the bay and is Oakland’s post populous region. To the east lies Livermore Valley, where Amador Valley touches the western edge and then continues west to Pleasanton Ridge. The Hayward Fault Zone runs through the most populated parts of the county, and the Calaveras Fault runs through the southeastern section. Both of these zones are major branches of the San Andreas Fault, making Alameda County prone to seismic activity.
