1. Just spoke to some friends in San Diego.

They said they hadn't felt a thing yet. Hopefully they won't.

10. Right near the park (Balboa?)

Not positive, but they said they hadn't felt anything. Yet. This was earlier today after the first report.

11. Could be substrate

balboa is built over basalt IIRC... that mesa is quite solid. I am on the river valley, sand.

Sister lives on basalt, she rarely feels them

12. I'm in College East

I felt the 5.3 and the 5.5.

I've been watching the eq site and it's been amazing seeing those litlle red and blue boxes pile up on one another.

4. swarms around the Salton Sea happen about every 6 months

This one happened to include a few big ones. No need to freak out, but it's a good reminder to double check your disaster supplies.

5. CNN just said this is the largest swarm since the 70s...

 

Everyone be careful.

7. I really, REALLY DO NOT want to cover a disaster

Working one sucks! (And the last time was as a paramedic)

What worries me is that the last ones in the series were the largest ones. The 5.4 was upgraded to 5.5... fun, NOT. I think this is not usual.

15. Brawley, California (another link/map)

Looks like this Brawley place is the current epicenter.

16. There hasn't been a volcano down there recently...

Volcanoes? In the Imperial Valley? At the south end of the Salton Sea, southwest of Mullet Island, are five small volcanic domes. They are oriented along a northeast trend, or perpendicular to the trace of the San Andreas fault system. The domes rise 100 to 150 feet above the valley floor, and collectively are known as Obsidian Butte. They are extruded into the Quaternary alluvium and are thought to be fewer than 20,000 years old.

...until it's not:



New Zealand dormant volcano erupts after a century

6 August 2012 Last updated at 23:55 ET



"It looked like Hiroshima", says one local resident of the ash cloud that spewed from Mount Tongariro

A New Zealand volcano dormant for more than a century has erupted, sending up ash clouds, disrupting flights and closing roads.

Mount Tongariro, one of three volcanoes in the centre of the North Island, became active just before midnight local time, with reports of loud explosions, spewing rocks and steam.

The 1,978m (6,490 ft) peak is in a national park popular with hikers.

No casualties or damage have been reported after the eruption.

Witnesses described a dramatic scene as the volcano erupted.

''I saw this beautiful, big cloud and I thought: 'Gee that looks like a volcanic plume'. Just as I thought that there was a great big orange flash," truck driver Bryn Rodda told New Zealand National Radio.

"It was quite impressive."

19. Excellent USGS link...

"The available data are insufficient to establish a pattern of volcanic activity to determine the likelihood of eruption. The high heat flow from the area and relatively young age of Salton Buttes, however, attest to the potential for future eruptions."

20. I hope it is gradual release of pressure along the San Andreas and subsidiary faults.

There has been too much movement along the western side of the Pacific plate in recent years for us not to expect some movement along its eastern side...IMHO.

I hope it is gradual and tolerable.

The bigger worry with Pacific plate movement is the Cascadia subduction zone in the Pacific Northwest. That one can produce 9.0+ quakes on a bad day.

22. Pretty sure there was a similar swarm in those "extinct" volcanoes around the time of Katrina.

I thought about that tonight while cooking dinner. My memory isn't that great though, and I haven't looked anything up.
