No tsunami warning so far. Not far off coast so maybe.

TSUNAMI BULLETIN NUMBER 001
PACIFIC TSUNAMI WARNING CENTER/NOAA/NWS
ISSUED AT 1641Z 07 NOV 2012

THIS BULLETIN APPLIES TO AREAS WITHIN AND BORDERING THE PACIFIC
OCEAN AND ADJACENT SEAS...EXCEPT ALASKA...BRITISH COLUMBIA...
WASHINGTON...OREGON AND CALIFORNIA.

... TSUNAMI INFORMATION BULLETIN ...

THIS BULLETIN IS FOR INFORMATION ONLY.

THIS BULLETIN IS ISSUED AS ADVICE TO GOVERNMENT AGENCIES. ONLY
NATIONAL AND LOCAL GOVERNMENT AGENCIES HAVE THE AUTHORITY TO MAKE
DECISIONS REGARDING THE OFFICIAL STATE OF ALERT IN THEIR AREA AND
ANY ACTIONS TO BE TAKEN IN RESPONSE.

AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS

ORIGIN TIME - 1636Z 07 NOV 2012
COORDINATES - 14.0 NORTH 92.2 WEST
DEPTH - 33 KM
LOCATION - OFF THE COAST OF CHIAPAS MEXICO
MAGNITUDE - 7.5

EVALUATION

NO DESTRUCTIVE WIDESPREAD TSUNAMI THREAT EXISTS BASED ON
HISTORICAL EARTHQUAKE AND TSUNAMI DATA.

HOWEVER - EARTHQUAKES OF THIS SIZE SOMETIMES GENERATE LOCAL
TSUNAMIS THAT CAN BE DESTRUCTIVE ALONG COASTS LOCATED WITHIN
A HUNDRED KILOMETERS OF THE EARTHQUAKE EPICENTER. AUTHORITIES
IN THE REGION OF THE EPICENTER SHOULD BE AWARE OF THIS
POSSIBILITY AND TAKE APPROPRIATE ACTION.

THIS WILL BE THE ONLY BULLETIN ISSUED FOR THIS EVENT UNLESS
ADDITIONAL INFORMATION BECOMES AVAILABLE.

THE WEST COAST/ALASKA TSUNAMI WARNING CENTER WILL ISSUE PRODUCTS
FOR ALASKA...BRITISH COLUMBIA...WASHINGTON...OREGON...CALIFORNIA.

OMG, I felt jell-o-like shaking lightly about 20 minutes ago, the 7.5 in Guatemala could be felt here in Tampa Bay area in FL

I shrugged it off, I was giving the kids a bath and thought it was just in my head from the bathtime play, whoa. Seriously, freakin' WHOA.

Been changed to 7.4 and depth has been changed to 41km, no tsunami warnings yet

reply to post by Nyiah


1800 km away? Somehow I think that is unlikely.

Just gone down to 7.4 by the way. Expect further reductions later.

YELLOW PAGER for fatalities and economic loses.

EMSC in @ 7.4 Mw

Potsdam in @ 7.2 Mw

SCARDEC not computed yet.

Unlikely, but certainly not impossible, Puterman. Debating whether or not to report it, coincidence or not. I'd rather report it, and let them decide if I did indeed feel it, but don't want to risk wasting anyone's time, either. Leaning towards reporting & letting them decide.

Mexico City, buildings shook. Distance from epicenter, about 1000km.

East coast quakes are felt farther. Central America and the Gulf are soft sandstones, shales, and limestone.

And that 4.5 in Utah right after. Is something happening here, that we should be really be paying attention to.

Dang, I run to menards for 45 minutes and things start getting very interesting

Interesting WSJ article. That helps illustrate how something like the 2006 GoM was felt as far away as it was, which I did feel here in the Bay area then, too (what I felt earlier wasn't nearly as strong, much more of a gentle jell-o-iness sway than the outright shaking in '06)

Also, when I reported what I felt, I noticed there was a zip code noted in the mention of places this quake was felt in. Central American/Mexican cities don't use zips, do they? Or rather, wouldn't they be listed as a postal code, and not a zip code? I might not be the only American that felt it stateside if that's the case.

My niece & her husband are in the Caymann's right now.
I'll have to see if I can get her on facebook!

Go with it. All I was saying is that it seems unlikely but that does not make it impossible especially since this will probably travel through the shale and give the GOM a good shake.

Mexicans got 7.3 Unk

Eight deaths are confirmed after the earthquake in Guatemala, according to the local fire chief.

Not quite sure what you are saying Muzzy. Even if you could get an accurate 7.7mb which you can't because of saturation, it would equate to about 7.5 Mw so not way off what EMSC and USGS give for the Mw figure. You can ignore the mb they give as that is calculated on the P wave arrival on just a few seconds or less. The moment calculation will be more accurate.

I see GFZ have come up to Mag 7.3 Mw now.

SCARDEC is still off line as is LDEO

Guatemalan president: preliminary reports of 15 dead in 7.4 earthquake -

Western Pacific it was.
Europe and the Med still seems to be slumbering.
It is the Sun I keep my eye on. Month to date only 16 minor flares.

Did anyone notice the cluster of quakes 50km NE from Tabriz in Iran?
Possible aftershocks of the quake in August, but speading wider all the time.
On its own not too much concern; after all this region is quite prone to quakes.
But add it in this is the probbable attack focus of Israel
- this 2nd highest rated area suspected of Iran Nuclear development.
Also housing the largest Iranian missile base.

Guatemala got hit bye 5 earthquakes today hope they all are alright

Just thought the Guatemalan's 7.7b seemed quite high compared to USGS and EMSC.
USGS have 6.6mb (off 512 stations) now which is quite a difference, and 7.0Ms which is a lot lower than the Russians 7.4Ms
2012-11-07 16:35:48.2, 14.14, -91.84, 33, 7.4Ms/16, 6.5mb/24

maybe you have got it figured out, but after 8 years of watching and reading I just can't see there is any way you ( or they) can calculate a conversion from mb to Mw or even Ms using a standard formula, it seems each part of the World has different results depending on the geology there.

eg on that one
USGS's 6.6mb converted to 7.0Ms
RAS's 6.5mb converted to 7.4Ms

Just heard back from my niece that's in the Caymann's.
They didn't feel anything, but they were snorkeling at the time!!!

When you read or hear someone telling you that fracking doesn't cause earthquakes, they're lying.
They'll blame injection only.
But there has been many studies that found frackquakes. England ( The British Geological Survey), Texas, Oklahoma, and now a study in British Columbia has made the connection.

switchboard.nrdc.org...

Insurance company acknowledge frackquakes exist and have decided not to cover them and warn homeowners that lease land to drillers that they need to make sure they're covered under the driller's insurance.

If you want to see a list of recent frackquakes, you need only look as far as The Okie Geo site.

There's a frackquake everyday.
