1 Bay Area Faults and Earth Material

2 Bay Area Faults

3 Earthquakes Today

4 Geological Cross-section

5 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)

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

7

8 Earth Materials and ground shaking

9 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
