2 past earthquakes

2 PAST EARTHQUAKES

  • 142 road closures in Loma Prieta

  • 140 road closures in Northridge

    18 FUTURE EARTHQUAKES

  • 17 Bigger than these earthquakes

  • 0 Bigger than New Orleans


What happens m 7 9 on san andreas fault

What Happens - M 7.9 on San Andreas Fault --

  • 1,330 total closures

  • Problems along I-280 and Hwy. 101 in San Mateo Co.

  • San Francisco a mess

  • San Mateo and Marin county coasts isolated

  • Problems near Bay at OAK, SFO and SJC


What happens m 6 9 on entire hayward fault

What Happens - M 6.9 on Entire Hayward Fault --

What does this mean

What Does This Mean?

  • There were only 142 road closures in Loma Prieta.

  • There were only 140 road closures in Northridge.

  • Our model for predicting the potential impacts of these closures should be Kobe, not either of these California earthquakes.


Utility system impacts

Sand boils

Pipeline Breaks


What happened in the very high liquefaction areas loma prieta quake

What Happened in the “Very High” Liquefaction Areas - Loma Prieta Quake

  • Water - 4-5 times more breaks

  • Natural Gas - 3 - 11 times more breaks

  • Roads - 1.3 times more surface, but 25 times more costly

Airport system impacts

Airport System Impacts


What happens m 7 9 on entire bay area san andreas fault

What Happens - M 7.9 on Entire Bay Area San Andreas Fault

  • SFO probably CLOSED

  • OAK probably CLOSED

  • SJC disruption - should be OK due to retrofit completed in 2003.


What happens m 6 9 on entire hayward fault1

What Happens - M 6.9 on Entire Hayward Fault
