In California, where the next "Big One" is an always-looming threat, some lessons learned from the 1925 Santa Barbara quake resonate even 100 years later, experts say.

One reason California is an earthquake outlier is that the San Andreas Fault and the faults around it are fast-slipping faults, meaning that they move quickly and generate earthquakes regularly.

Southern California's last magnitude 7.9 earthquake occurred in 1857, when the San Andreas ruptured between Monterey and Los Angeles counties.

The last “big one”-level moments in California’s recorded earthquake history were the 1857 quake in the central third of the San Andreas Fault and the 1906 earthquake in the northern third.

Recent earthquakes that have shaken California may be a result of a Southern California fault line considered even more dangerous than the San Andreas fault.
