On Friday evening, a 7.1 magnitude earthquake hit Southern California.
According to United States Geological Survey, the 7.1 magnitude earthquake that hit Southern California is the largest temblor in the region in two decades.
It was five times bigger than Thursday’s 6.4 -magnitude earthquake.
“Every earthquake makes another earthquake more likely and that’s what we’re seeing right here,” seismologist Dr. Lucy Jones said Friday. “The first one is often not the biggest one.”
About 20 percent of earthquakes strike in both directions, which may have been the case Friday, Jones added.
The tremors were felt in Las Vegas and Los Angeles and as far away as Mexico.
