Presentation Transcript

  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. Earth Materials and ground shaking

  8. 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
