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.

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.
