LOS ANGELES—Late Monday night on June 14, almost two dozen rounds of earthquakes hit southern California as a result of the tremors that occurred two months ago near the U.S.-Mexico border.  It was centered 90 miles south of San Diego reportedly.

Apparently, these types of events are likely to happen and are fairly normal when considering these so-called aftershocks. “Aftershocks can go on for months or years,” a California Institute of Technology seismologist Egill Hauksson told the AP.

Surprisingly, the 7.2 quake that centered on Mexicali is the same spot where the recent earthquake has hit. The latest incident was reported by authorities to have only been a magnitude of 5.2, nonetheless having enough of an impact to interrupt a Padres-Blue Jays baseball game.
