Terremotos?

" Yes. Most of California is at high earthquake risk, and the Bay area has more than its share of active earthquake faults. The San Andreas fault, located less than 20 miles away across the Bay, produced the great San Francisco earthquake of 1906 (a magnitude of 8.3), which destroyed the city and caused great damage in surrounding areas. It also caused the Loma Prieta earthquake in 1989, which occurred during the World Series baseball championship and registered a magnitude of 6.9. The Hayward fault, just a couple of miles east of the Village at the base of the Berkeley Hills, has had two earthquakes in historic times with magnitudes of about 7, in 1836 and 1868. These faults and others are capable of repeat performances at any time.

Seismologists assert that future large earthquakes are inevitable: It’s a question of when, not if."
