Keep getting bigger.
Unusual.
He has to be weeping at the whole state of this crazy messed up world.
About 160 miles from Imperial Beach to Salton Sea, mas o menos.
As did I.
Maybe LA and San Fran will fall of the coast ping.
Thanks. You are correct. I honestly had no idea that these volcanoes were in that area.
From the article I should have read more carefully:
“The buttes are small volcanoes with an explosive past. Miles below them is a pool of magma that is 15 miles wide. About 8,000 years ago, the buttes erupted, causing magma to flow which cooled into obsidian rock.
The damage from those eruptions was limited to the surrounding area, but if a major earthquake hit along the San Andreas Fault, geologists said there could be trouble.
“It really pumps energy into a freshly enlarged magma body,” said Abbot. “That would be a worst-case scenario.”
Unstable magma may find a path to the surface, which would result in the buttes erupting, oozing lava and spewing ash.”
Muy interesante...

Series of quakes rock San Diego region

A series of three sizable earthquakes erupted early Sunday afternoon on the San Andreas fault, south of the Salton Sea, causing shaking that was felt across the region from San Diego and Imperial counties to northern Orange County.m
The first quakehead a 5.3 that occurred four miles southeast of Westmorland at 12:30 p.m, according to the U.S. Geological Survey.
That was followed one minute later by a 5.4 quake in the same area. Then there was another 5.3 at 12:32 p.m. a short distance away, the USGS said.
Since then there have been two quakes above 3.1 and two quakes above 4.0 in that area.
Three quakes of that size close in time is unusual, but it does not necessarily mean a larger event is imminent, earthquake experts.
However, the quake occurred at the very southern end of the San Andreas. Scientists are concerned that the entire stretch of the San Andreas will someday snap, causing a catastrophic quake.
The quake caused a lot of shaking in the heavily congested stands at the Del Mar race track and people did look around but there was no panic.
Tom Rockwell, seismologist at SDSU said: “Today’s event occurred in the Brawley Seismic Zone, an area where the San Andreas and Imperial faults come together. It’s a very seismically active region.:
But Rockwell said having three 5.0 earthquakes is very unusual so close in time.
“The big concern is if a moderate earthquake would lead to a larger earthquake on the San Andreas,” Rockwell said.
Mayhap the illegal invaders dug a tunnel too deep to get across the border. :)
They just keep coming right now.
Thanks for the update. YES, the number of these quakes is very unusual.
Just sat thru this swarm. We had a 7.2 on Easter a couple of years ago but these were frightening. I thought at least one would be at 6.5 or above but I got fooled because we had three separate quakes 5.3 then 5.4 and finally 5.3 all in under 50 seconds.
It is already ~200 ft below sea level.
Stay safe!
I’ve got the earthquake, real-time list going for the USGS. Almost all the quakes for the last 4 hours in Brawley just spit out the “computer message, not reviewed by a seismologist”. Wondering why? I can’t fathom a reason unless their computer has taken over. (slight attempt at humor) Any ideas?
Three more have just hit in the last few minutes, all the 3.0 varierty.
The first few were 4 pointers and then a couple of 5 pointers, one of which I felt over in San Diego, a mild jolt with a little creaking of the building.
