13 significant earthquakes, including one measuring magnitude 4.8, shook the state very early on Monday morning in a span of just 25 minutes…
Parts of California were hit by more than a dozen earthquakes overnight, with 13 shaking the state during a span of just 25 minutes.
“Good morning Southern California! Did you feel the magnitude 4.8 earthquake about two miles north-west of El Centro at 12.36am? The #ShakeAlert system was activated,” the United States Geological Survey Shake Alert account posted on X.
The good news is that none of the earthquakes were large enough to do much damage.
But the magnitude 4.8 quake was keenly felt by some local residents…
When people hear about earthquakes in California, most immediately think of the San Andreas fault system, but it was actually the San Jacinto fault system that caused most of the problems early on Monday…
The quakes appear to have been caused by the San Jacinto fault system, meteorologists have said. It is one of the most active faults in southern California.
Overall, the USGS says that there have been 27 significant quakes of at least magnitude 2.5 that have hit the state within the past 24 hours.
That certainly isn’t anything to freak out about, but it is definitely noteworthy.
And all of this activity comes just a few days after a magnitude 4.6 earthquake shook up the wealthy residents of Malibu…
A magnitude 4.6 earthquake struck about 8 miles northwest of Malibu on Friday, according to the United States Geological Survey.
The earthquake was reported at 1:47 p.m., the USGS website said. It occurred at a geological depth of 13.9 kilometers, or nearly 9 miles.
The USGS is reporting at least a dozen aftershocks, with the largest measuring at a magnitude of 3.0.
We haven’t seen this sort of sustained seismic activity in southern California in a long time.
Is something very unusual starting to happen?
Let’s keep a very close eye on the numbers coming from the Southern California Earthquake Data Center.
If the number of quakes in a week rises above 1,000 and stays there, I would say that there is cause for alarm.
As I wrote about earlier this month, scientists assure us that we are way overdue for “the Big One”.
When it finally arrives, the ground on the western side of a major fault line could suddenly drop by several feet (or more), and because much of that area is just barely above sea level that could potentially allow the Pacific Ocean to come rushing in.
Let us hope that nothing like that happens any time soon.
But right now the flooding that has recently occurred in the region is putting a tremendous amount of stress on the fault lines.
Unfortunately, it can take a long time for extra water to disappear.
Just look at what has happened in Death Valley. Hurricane Hilary dumped so much rain on the area last August that it actually created a lake, and it is still there after all this time…
