There's now an entire generation of Californians who have grown up without experiencing the damaging earthquakes we saw in the 1980s and 1990s.

The earthquake struck at 7:28 a.m. Thursday morning, and it was centered 3.5 miles northwest of Malibu and 4.9 miles southwest of Agoura Hills, according to the U.S. Geological Survey. It was about 6.

At 10:34 a.m., a 3.9-magnitude quake hit 3.7 miles north-northwest of Eastvale, near the 3.5-magnitude quake close to Ontario and Eastvale around a half hour earlier. the U.S Geological Survey reported.
