Earthquakes continue to rattle southern California after a 4.9 struck east of San Diego at 6:53pm PT / 9:53pm ET. The quake was centered roughly 10 miles east south east of Anza, California at a depth of about 10.6km. The earthquake was felt throughout the Los Angeles and San Diego metro areas.
The Pacific Tsunami Warning Center says there is no threat of a tsunami from the 4.9 quake or its weaker aftershocks. Subsequent aftershocks were rated at 3.6, 2.9, 3.0, 2.6, 3.7, and 2.6. The Pacific Tsunami Warning Center issued a very brief statement: “There is NO tsunami danger from this earthquake.”
Seismologist and author of “The Big Ones” Dr. Lucy Jones said while a larger quake around the San Jacinto fault is possible, tonight’s quake would not directly impact the San Andreas fault and trigger a larger quake there.
Do not worry about the San Andreas. A M4.9 can only affect an area a few miles across. But the San Jacinto fault itself is capable of major M≥7 quakes and the chance of a quake on the San Jacinto is now increased. The chance of a quake of M≥6 is less than 1% https://t.co/m62JN4UhcO

USGS says there’s a 50-50 chance that earthquakes stronger than the 4.9 that struck earlier could hit within the next day.
