L.A. Earthquake Reveals Fault Line

Monday’s 4.4 earthquake in Encino, Calif., thankfully didn’t cause any injuries, but it did rattle people enough to realize seismic shakes go beyond the notorious fault lines of the San Andreas and San Fernando. The largest earthquake in Los Angeles in four years, it stemmed from a barely noticed fault line under the Santa Monica Mountains, and was the strongest to hit there in 80 years. Los Angeles’ most recent majorly destructive earthquake, 6.7 in Northridge in 1994, also occurred on a previously unknown fault line.
