In other words, expect it to be reviewed by 10 more, and when they all come to a decision next week or next month on what magnitude it was, on who's scale, you can dig it up in the archives.

OK...El Hierro activity seems to be reducing, but could someone tell me if I am right saying that there seems to be increased activity ALL OVER the Canaries generally?
Here is a link to seismo charts for the region all neatly put on one page.

That is going to go down I think, and before the 7 days I guess. Wait until they get in the office today. Only 3 stations registered a magnitude on the phase data - I have not seen that few before and only 1 of those registered a 6.0. The mblg was 4.9

RABL ePn 05:05:40.27 1.7 2.0 35 g:9.0+1 1.1 6.1 RABL
PMG ePn 05:06:25.09 3.2X 5.2 227 g:2.8+0 1.0 5.0 PMG
HNR ePn 05:07:20.38 -1.5X 9.6 112 g:6.7-1 1.0 4.8 HNR

With so few on the automatic primary body wave calculations they are going to have to get together some secondary wave calculations. According to my program AU.RABL is the closest public seismo and is the first on that list: RABL.AU..BHZ.2011.291 but HNR hardly shows it: HNR.IU.10.BHZ.2011.291

I think I won't put it upon my blog just yet!!

Um, my take on that would be storm. You may not be getting it in Blighty in the sheltered regions of Birchwood and surrounds but it has been blowing fairly hard here on the exposed west coast and I guess t'Atlantic is a bit ruff!

Morning Mr PuterMan sir,
Thank you for that.....off to check the weather reports for Canaries! But I already have my doubts that it's the weather, as there have been a few reports a couple of days ago that people felt eq on La Palma and Tenerife. BTW...windy here too....bet it's bad on my home isle of Anglesey...that Irish Sea can be a b*gg*r at times! Been through a couple of hurricanes there!

Thanks, TA,

it looks like your email worked! GEE is now running better than yesterday. Still slower to load than previously but not bad. If I get similar problems in future I'll do as you did and let them know.

Best regards,

Mike

WeatherUnderground is a good resource. I took a look and it's rather blustery in the Canaries today. Winds getting up around 30 km/h in some locations. (Click on the individual stations in the list for more detail.)

TA, I'm using your post for reference as it shows that the quake off Oregon on Oct 13 was downgraded from 5.9 to 5.3.

Now, to the point: there was some discussion that in the next day or so after this quake, there were no aftershocks. I and a few others made the point that while quakes in this mag range in that region generally have aftershocks, sometimes they don't. (I cited an example of one from Nov 2008 in a post but I think other examples were mentioned as well. Another I can recall offhand was in Feb, 2010.) It's not even just a function of its magnitude as there have been other examples of quakes in the same region of around the same mag, that have had aftershocks.

Anyhow this quake looks like it's one of those that don't have aftershocks. Here's a screenshot I took around an hour ago:


Source: USGS (Note to future readers: the link will drop off the system before long, but the quake can still be found by searching databases like NEIC, for example.)

So, no aftershocks. Does it mean anything? Probably yes. But it doesn't have to mean it's anything to worry about. We certainly can't conclude that it's a precursor for something way bigger. The previous events with no aftershocks in the same region were not, after all.

Although little....I really don't like all the little quakes crackin' in the United States. It makes me feel just a tad bit uneasy.

In one week..... we have.....

Oklahoma, Oregon, Virginia, Arkansas, Nevada, Washington, Utah, South Carolina, California, Arizona, New Mexico.

It is not out of the norm for us to have quakes but man...... it just seems as though they are coming more frequently. Feel free to tell me my observation is wrong.

Check it out on USGS........earthquake.usgs.gov...

I agree, there are a lot of quakes in places of the US that we don't normally see. This one is in northern Oregon:

With Mt. Ranier rumbling the other day, it makes you wonder what is going on underneath.

Be Well.

If you look on earthquake 3-d you will see the us quakes are all in a strainght row..Dividing the north from the south..It doesnt got past Arkinsas.

reply to post by Bishop2199


The earth is shifting big time....Not good what so ever...I have never in my life seen so many quakes all over the world.

reply to post by Bishop2199


I was just looking at that...the PNSN volcano webis show that St Helens and Rainier both recorded that 2.8 near Mt Hood. I wonder if a signal travels more clearly through magma that rock? I don't have time at the moment to check other stations.

If these southern quakes keep happing in a straight line it will take mexico and seperate it from the U.S. i dont know how to get the earthquake 3-d on here...

Im going to try something here..It didnt paste or copy never mind....

"El Paso’s ‘Juicy’ Shale Assets May Attract Bidders"

"India’s Reliance Industries Ltd. (RIL), Norway’s Statoil ASA (STL) and Occidental Petroleum Corp. (OXY) may be among bidders for El Paso Corp. (EP)’s oil and natural-gas unit as the companies seek to expand their stakes in U.S. shale fields.

Kinder Morgan Inc. is seeking a buyer for El Paso’s exploration business to help pay off debt from this week’s $21.1 billion takeover of the rival pipeline company, which creates the biggest gas pipeline network in the U.S.

The assets for sale, which include more than half a million acres of shale fields, may command a $7.3 billion price tag, according to data compiled by Bloomberg. Deep-pocketed bidders from outside the U.S. are among the likely bidders, Dan Morrison, senior energy specialist at Global Hunter Securities LLC in Fort Worth, Texas, said in an interview yesterday.

“This will put out one of the juiciest acquisition targets we’ve seen on the market for a long time,” Morrison said. “The foreign buyers can certainly pay a premium because they need the operating entity in addition to the assets.”

Reliance, which reported cash of 614.9 billion rupees ($12.6 billion) this month, formed a joint venture with Atlas Energy Inc. and bid this year to buy the company before it was sold to Chevron. Statoil has formed joint ventures with Chesapeake Energy Corp. (CHK) to develop natural gas fields in Pennsylvania, and yesterday agreed to pay $4.4 billion in cash for Austin, Texas-based Brigham Exploration Co. (BEXP) "
