Exam # 3

 Topics covered: earthquake hazards and risks; prediction (long and short term); earthquake monitoring, California legislation and insurance, structural design (what works, what doesn’t), how are you prepared

•  Earthquake hazards: ground shaking; ground rupture; landslides; liquefaction-definitions and    locations where these hazards will occur in the Bay Area

• Tsunami: definition, characteristics, how they move through the oceans, arrive on land, and how the DART program helps in the warning system.

• Mexico City earthquake: particulars; period vs resonance, earth materials versus structures, building design.

• New Madrid seismic zone: tectonic setting; compare and contrast with California; expected risks and damage versus 1811.

• Kobe Earthquake; particulars; seismic waves; hazards; structural hazards.

• Northridge eq: particulars; hazards and structural hazards

• Compare Hayward fault with the Kobe Earthquake.

For the San Francisco, Long Beach, San Fernando, Mexico City, Northridge, Kobe, Loma Prieta earthquakes know the earth materials, earthquake hazards, structural hazards and legislation.

 Haicheng, China -earthquake-only successful prediction. Why: understand what are the precursors to an earthquake.

Mexico City earthquake- earth materials, structural damage, seismic waves

California earthquake legislation: Alquist-Priolo Special Studies Act and California Seismic Hazards Mapping Act, worksheet

Seismic safety commission:

 Earthquake insurance: http://www.earthquakeauthority.com/about/about.html

 Prediction: short term (precursors); long term (probabilities, seismic gap, recurrence interval (historical, paleoseismic), characteristic of fault segment (creep vs. locked)- Is that all?

http://neic.usgs.gov/neis/predict/predict.html

 Long term preparation- retrofitting- three ways,  two specific examples- roads and bridges and/or buildings

What would you do exercise?

Structural hazards-what to do and not to do- shape and material- know two specific examples of bad and two of good

http://geopubs.wr.usgs.gov/fact-sheet/fs017-03/

 Non-structural hazards- several specific

 Understand the good points and bad points of earth materials, structural hazards, non-structural hazards, fault proximity of your residence.
