April 3, 2020 (San Diego's East County) -- A quake measuring 4.9 on the Richter scale occurred this evening at 6:53 p.m. near Anza, at the boundary of San Diego and Riverside counties. The U.S. Geological Survey earlier ranked the quake a 4.6 but later upgraded its intensity.
The shallow quake, at a depth of about 6.6 miles, occurred along the San Jacinto fault which seismologists have previously indicated is capable of generating a powerful quake up to 7.5 in magnitude. There is a 5 percent chance that this quake could be a precurser to a large quake within the next 48 hours, seismologist Tom Rockwell with San Diego State University told the San Diego Union Tribune.
The quake rattled buildings in Palm Springs and was felt as a roll with a sharp jolt across San Diego and Riverside Counties, with reports from as far away as Los Angeles.
