Hey there Muzzy!!! Glad you are in the mix adding valuable info as always. I'm wondering that you posted us for Brawley only so the stats are not taking the town Westmoreland into account,for instance?

Series of Earthquakes Rattle Southern California
SAN DIEGO August 26, 2012 (AP)

abcnews.go.com/US/wireStory/series-earthquakes-rattle-california-17083595

Dozens of small to moderate earthquakes struck the southeastern corner of California on Sunday, causing minor damages to structures and rattling nerves in a small farming town east of San Diego.

The largest quake registered at a magnitude 5.5 and was centered about three miles northwest of the town of Brawley, said Robert Graves, a geophysicist with the U.S. Geological Survey. Another quake Sunday registered at magnitude 5.3.

More than 30 additional earthquakes with magnitudes of at least 3.5 jiggled the same area near the southern end of the Salton Sea, Graves said.

"The type of activity that we're seeing could possibly continue for several hours or even days," Graves said.

At the El Sol Market in Brawley, food packages fell from the shelves, littering aisle ways.

Several glasses and a bottle of wine crashed to the floor and shattered at Assaggio, an Italian restaurant in Brawley, said owner Jerry Ma. The shaking was short-lived but intense, he said.

"It felt like there was quake every 15 minutes. One after another. My kids are small and they're scared and don't want to come back inside," said Mike Patel, who manages Townhouse Inn & Suites in Brawley.

A TV came crashing down and a few light fixtures broke inside the motel, Patel said.

A Brawley Police Department dispatcher said several downtown buildings sustained minor damage. No injuries were reported.

The first quake, with a magnitude of 3.9, occurred at 10:02 a.m. The USGS said more than 100 aftershocks struck the same approximate epicenter, about 16 miles north of El Centro.

Some shaking was felt along the San Diego County coast in Del Mar, some 120 miles from the epicenter, as well as in the Coachella Valley, southern Orange County and parts of northern Mexico.

USGS seismologist Lucy Jones said earthquake swarms are characteristic of the region, known as the Brawley Seismic Zone.

"The area sees lots of events at once, with many close to the largest magnitude, rather than one main shock with several much smaller aftershocks," Jones said.

The last major swarm was in 2005, following a magnitude-5.1 quake, she said.

Sunday's quake cluster occurred in what scientists call a transition zone between the Imperial and San Andreas faults, so they weren't assigning the earthquakes to either fault, Graves said.

thanks anmarie, found it

reply to post by MamaJ

yep westmorland is in there
pages are flipping too quick here on ATS,
I edited my post to say i found another 165 quakes that anmarie pointed me to below2.5, I'll do another map.
easy now I have the programme set up with the parameters

new map, last quake is at the top of the list (down to magnitude 0.5)

goo.gl...

not much difference, about 3 more tonnes of TNT released from the < 2.5's and the new quakes since 27/08/2012 00:58:45 worth about a mag 3.5 extra

Here we go again. Got quiet, then a 5.1 (changed to 4.9)

With a 7.4 off El Salvador for a change of pace.

It appears there is a local tsunami warning for Central America.

THIS EARTHQUAKE APPEARS TO BE A SLOW EARTHQUAKE WITH ADDITIONAL
TSUNAMI POTENTIAL. THEREFORE A WARNING IS BEING ISSUED.

... A TSUNAMI WARNING IS IN EFFECT ...

A TSUNAMI WARNING IS IN EFFECT FOR

COSTA RICA / NICARAGUA / EL SALVADOR / HONDURAS / GUATEMALA /

FOR ALL OTHER AREAS COVERED BY THIS BULLETIN... IT IS FOR

so what is a SLOW moving E/Q??? please...!


seeya

I'm expecting there to be a bumpy ride in many places during the last 4 months of the year (rather than previous two where most energy was released during first few months.

I mean, you just get the feeling that something BIG is due to really shake or blow somewhere soon in North America!

And maybe not exactly where everyone is expecting...

Final note, even supposedly EXTINCT volcanoes have apparently been wakening up, along with a site load of others every week!

Just as well I don't subscribe to the Dec 2012 theories, or I'd be really starting to get worried

I don't think this is finished yet

FWIW the Hiroo, Hokkaido aftershocks seem to have tapered off, with just 11 in the last 11 hours, largest a 2.7 duh:
total of 96 up to 27/08/2012 03:09:50.8

Does anyone here think that TS Isaac has anything to do with the increase?

reply to post by kennvideo


I don't know. I thought there could be influences created by hurricanes but haven't found much evidence over the years to directly tie it in. In another twenty years I think that they will be able to predict a high percentage of quakes by tying many things happening around the world and in space together. Even then I doubt if they will ever hit 50 percent reliability but that's much better than we have now at predicting them.
