Geological Cross-section

•General breakdown:•Baymud: flat area near bay- marshland•Unconsolidated sediments: area that is flat toward the hills- sediment from hills filling in basin•Bedrock: hills (not all hills are stable but for this discussion we will assume this)

San Jose State University
San Jose State is built on unconsolidated sediments and is surrounded by mountains (bedrock).

When the Bay Area Quakes
• Understand general earthquake hazards• Know the general location of faults in the Bay
Area• Have a general idea of the topography and earth
materials of the Bay Area• Movie: specific locations of hazards; structural
failures (Cypress structure addressed); forecasting eqs- recurrence interval and seismic gap
