Hospital evacuated in the earthquake swarm zone.


"A rash of up to 70 moderate earthquakes were felt on Sunday.... "


" As of 4 p.m., Pioneer Memorial Hospital in Brawley, Calif., was beginning to evacuate patients due to the ongoing quakes
in the area. About a dozen patients were transferred to hospitals in San Diego and Riverside Counties, but the majority of
the hospital was operating with a generator. "

Boy, talk about hyperbole.

A "moderate" quake has a magnitude somewhere between 5.0 and 6.0. Brawley, California, had precisely two "moderate" quakes. One that was 5.5 and the other that was 5.3.

They also had a couple 4.9 and one 4.8 quakes. Those are "small" quakes that are unlikely to do any damage. Anything under 4.0 and I seriously doubt anyone even felt them unless they were standing on top of the epicenter. They certainly do not rate as "moderate" quakes.

The news link I posted previously says there is some damage and power outages.
Schools will be closed tomorrow to access damages.


This link also reports some minor damages to homes and businesses.

I am not surprised. Any quake that has a magnitude 5.0 or larger is a concern, and Brawley had two within 5 miles of the town.

IIRC, that movement happened before and has now stopped.

Currently the coast of Southern California is moving northwest-ward along the San Andreas and associated faults. In some-odd thousand or so years, L.A. will be on a latitude with, say, Reno.

Having been at the epicenter of a 5.1 and in the next town over to a 4.9, I guarantee that such a "moderate" quake will wake you up in a hurry! I'm guessing the hospital is evacuating patients because they remember the Easter earthquake, which was quite serious. I agree that anything 4.0 and under can easily go unnoticed.

I agree. Like I said in an earlier post, when they reach 5.0 or above they cease to be fun and become a concern. I remember one 5.4 quake where I was sitting in the dentist chair getting a crown. That was an interesting experience.

There is certainly nothing wrong with being prudent. I certainly cannot fault the hospital for looking out for the well-being of their patients. Just because Brawley experienced two quakes larger than 5.0 does not mean that there will not be an even larger quake in the near future.

When quakes are really big (above 7.0) they tend to last a long time. Most quakes are over in just a few seconds, but the really big ones can last minutes. The last really big quake we had was in November 2002, and it measured a magnitude of 7.9. That quake lasted for two minutes before the shaking stopped.

There have been a few off the coast of Washington right on our subduction zone recently too.
