Southern California experienced 5.2 magnitude earthquake — are more to come?
A 5.2-magnitude earthquake jolted Southern California early Friday, prompting some to wonder whether something much stronger is coming.
The moderate quake occurred about 13 miles from Borrego Springs, a community in the eastern part of San Diego County, just after 1 am PT, according to the U.S. Geological Survey (USGS).
Residents in San Diego and parts of Los Angeles felt the shaking, too.
Fortunately, there were no reports of injuries or damage, San Diego Sheriff’s Lt. Andrea Arreola said.
About a dozen small aftershocks hit the area, after the initial earthquake, the strongest being a 3.8-magnitude quake.
The first earthquake, which happened near the San Jacinto fault, one of the most historically active faults in region, had some people on social media asking whether this was a precursor to something much stronger.
USGS scientist emeritus and seismologist Lucy Jones told us that the earthquake probably wont trigger something more powerful.
On Twitter, Jones shared a message stating the quake should not prompt alarm.
“We have never seen a San Andreas earthquake triggered by a San Jacinto earthquake. The 2 faults are 25 miles apart.”
This means it is not likely the earthquake would trigger something more powerful on another fault line because of their sheer distance from one another.
And the aftershock activity following the morning’s earthquake are normal, she posted later on the social media site.
Geologist Julian C. Lozos discovered that the San Andreas and the San Jacinto faults may have ruptured together about 200 years ago, in march, creating an earthquake that was felt from north of Los Angeles to San Diego, based on historical data captured by missionaries in those areas.
He said in his report that it may be likely that this situation could happen again in the future.
“If there’s a joint rupture it will create a larger earthquake, especially if it starts on the San Jacinto,” Lozos said back in March. “Say you’re stressed out and you snap. You might then stress out your friend too. That’s that same way faults work. They stress each other out.”
