  1. California Geology So what can we do about it Science Std: Geo # 9d

  2. California has a variety of hazards Active and Dormant Volcanoes Active Fault Zones Landslides Tsunamis Costal erosion

  3. California has a variety of hazards But what can we do about it…. How can we plan for them How can we reduce the danger How can we reduce the damage

  4. California has a variety of hazards Focus on our main hazard Earthquakes…..

  5. Earthquakes Planning 2 main areas for planning Structure Survival Minimizing Effects

  6. Earthquakes Planning Structure Survival Engineers would like to make every building earthquake-proof, but can't because it's too expensive.

  7. Earthquakes Planning Structure Survival they recommend making dams and public buildings earthquake-proof

  8. Earthquakes Planning Structure Survival All other buildings should be earthquake resistant to avoid deaths.

  9. Earthquakes Planning Structure Survival And not only buildings – but roads and bridges should be made earthquake resistant – not earthquake proof

  10. Earthquakes Planning Structure Survival So how do you make a building “earthquake resistant”

  11. Earthquakes Planning Structure Survival Base Isolation The building is put on giant rubber shock absorbers The shock absorbers allow the ground to move and keep the building still

  12. Earthquakes Planning Structure Survival Wall support Homes or other buildings have additional reinforcements These make the wall more stiff to resist motion

  13. Earthquakes Planning People Survival Earthquake Kit You should have a kit ready should there be an earthquake But what is in an earthquake kit?

  14. Earthquakes Planning People Survival Experts recommend that you make three identical emergency kits Earthquake Kit One kit in your car One kit at home One kit at work

  15. Earthquakes Planning People Survival Into each kit you should put.. • Water and food to last at least three days (your car trunk is a handy place for these bulky items) • Water purification tablets • Heavy-duty gloves • A first-aid kit • A minimum of $100 in cash (automated teller machines and banks may be shut down following a quake) • Family photos and descriptions (to aid emergency personnel in finding missing people) • A flashlight and portable (or solar-powered) radio • Extra batteries • Goggles and dust mask • A personal commode with sanitary bags

  16. Earthquakes Planning People Survival The most important item is…. Water…. You should have a minimum of 5 gallons stored somewhere

  17. Earthquakes Planning What about when we are planning for new areas? Would it be better to build tall buildings…. …or flat park land….. …in an area that has earthquakes?
