Earthquakes! An earthquake, or seismic event, is a sudden movement of Earth’s crust that releases energy.

 A vibration of the Earth produced by a rapid release of energy  Often occur along faults – breaks in the Earths crust and mantle (plate boundaries)

PREDICTION Paleoseismology: Documenting and evaluating past events. 1.) Usually done with looking at offset layers in sediments in trenches 2.) Calculate.

Bay Area Faults

Earthquakes Today

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).

Earth Materials and ground shaking

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
