For decades Californians have been warned repeatedly that the “big one” is coming. Someday a massive earthquake is going rip through the San Andreas Fault, possibly causing thousands of casualties and billions of dollars in damage. So far nothing that serious has occurred in recent memory. With the exception of the 1906 San Francisco earthquake, the state has been largely spared from any serious tectonic disaster.
But according to some experts we may not have to wait much longer, especially in regards to the southern portion of the San Andreas fault near San Diego and Los Angeles. That’s because it’s been so long since this fault has had an earthquake. The pressure is building there. The fault typically has a major earthquake every 100 years or so, but this particular portion hasn’t experienced a major quake since 1857, which was a magnitude 7.9.
