Quake Watch 2010

2009 Samoa quake was a 7.9 and 8.0 together

Don't know if anyone read this or posted it already, it was in this mornings paper.

"New research into the earthquake responsible for the deadly 2009 tsunami in Samoa and Tonga has found it was caused by not one, but two near-simultaneous quakes.

The New Zealand-led research helps explain why the resulting tsunami did not fit predictions; that is, the waves were larger than expected in some areas and failed to arrive at anticipated times in others". ........... more

edit;
heres another news story, with a different slant ...... 3 quakes

Strange, I have this showing as a 6.2 AND a 6.1


Edit: They deleted the 6.2 now so there is only the one in my program.

is this the same one with revisions to data or a different one?

That's the same one - same ID First it was 6.2, then 6.1 and now 6.3.

Tomorrow it will be a 4.7 and on Sunday it will become a 7.4

IDK - was thinking this the other night but thought I just might be grasping - but now it just keeps getting more pronounced. So, I will throw it out here to your for opinion - Does anyone other than me see a circle Here ?

OMG...this is kinda wierd. I almost provided a link and comment to that exact map yesterday. I was checking out the recent maps when I pulled it up and I thoght he EXACT same thing. So it's not just me?

Oh, and I added my additional comments to yours over on the other thread about the 'sonic booms'. Yah, right. We happen to have two or three very large explosive occurances in the same area of the tremors and we are suposed to buy that? I don't think so!

I think there is some major action going on right now here.....some obvious, some brewing under the surface, some....building up.

Isn't that that the truth.

So basically what they are saying is that there is a movement of the plates that is the equivalent to the effect/power of a mag 7 quake, but which is not accompanied by earthquakes (aseismic) other than the preceding deep tremors.

From the Wiki article:

For some GPS stations around the ETS, there is an apparent slipping back or reversal of direction of the normal tectonic plate movement, although the fault motion remains consistent with subduction.

It goes into reverse? *walks away with mind boggling trying to imagine reverse subduction*

You know what this reminds me of?

Quite often, when talking about Yellowstone and the caldera, I compare it to 'mother nature' taking a big breath and is waiting to let it out.

This whole reverse subduction makes me think along those same lines. Call it 'taking a breath' or 'expanding earth theory' (I just made that connection)...the plate would HAVE to slide backwards if there was reverse pressure...why else would it?

*shaking head*....this all just keeps getting wierder.

Does anyone else think it is a little odd that the Marianas 6.3 is showing on every recorder in the world?

Live Internet Seismic Server

It was only a 6.3

Edit:I thought I had better put a couple of plots up as it will be off the radar in 7 hours.

Check out Iceland quakes - nice little bunch of them earlier, including a 3.1, near Kistufell area.

That does appear to be much larger than a 6.3 - it even rocked Texas

They have updated the list from Yesterdays Utah events yet again

MAP 2.1 2010/08/18 14:41:49 37.641 -113.209 2.7 12 km ( 7 mi) NNW of Kanarraville, UT

I found this interesting article today:

Deadly Samoa-Tonga Earthquake Concealed Two Other Quakes, Seismic Sleuths Discover

www.sciencedaily.com...

I didn't feel up to creating a thread on this, so I decided to post here. I hope that is appropriate.

I hate when Yellow Squares appear. Especially when they are suppose to be automatically posted. (Unless I just happen to miss this one - which happens). But with keeping a very close eye on the Juan de Fuca Plate and the deep tremor etal in the area - idk

So for the 16th there was also this

4.4 2010/08/16 12:05:17 40.771 -125.147 23.3 78 km ( 48 mi) WNW of Ferndale, CA

Are those series of Iceland quakes also near Bárdarbunga volcano?

www.volcanodiscovery.com...

Okay, there's a lot going on right now and it's getting a bit tough to keep up!!

First...some interesting stuff going on up in Iceland. Could we finally be seeing some signs that the other volcanoes (hopefully not Hekla) are gonna join in on the fun?

That Marina quake was very shallow. There is NO way it should have shown up around the world the way it did. Either they are way off on the mag, or the depth or both. HUGE list of recenet decent size quake there the past few days. Wouldn't be surprised at all to see a sizeable one being built up to.


AnnMarie....I just noticed the action going on at the Southern end of the Juan de Fuca plate. Check out THIS Hmmmmm


The deep tremors continue. They seem to be slowing down however on updating the website. It's a bit frustrating. I think the action is decreasing, but it hasn't followed what has been the pattern in the past, with it traveling up to the canadian boder. Instead it made it about halfway, and then started migrating south again. In looking at that map, it looks as if Montana, Idaho, Wyoming and Utah are all having a decent amount of small quakes too. It would make sense, don't you think? I mean, if the subduction zone were moving in either direction, it would send waves throughout the whole western half of the country.

Edit to add: check out THIS webicorder. It is from pretty much the middle of Puget Sound, Washington.

I posted that story yesterday (at the top of page 195)

But thats OK you can never have too many sources.

reply to post by PuterMan


Depends where in Russia that one was from? you cropped the station name off it
That size of signal it would likely be from Kamchatka?, as most Pacific 6's look the same all around the Pacific Rim stations no matter where they occur in the Pacific.
That size also looks about the same as the one from Karori New Zealand (NZSO) when I seen it yesterday.
I've noticed low 6's show all over, but below 6 then they tend just to show locally, like 5000km away.
Just generalising mind you.

The USGS must have been on vacation or seriously wrapped up in something else. There are many quakes being added to the maps and lists at the moment.

I am thinking the 17th and 18th had them very busy and scramling - I wonder what else will pup up.

We have more quakes in UT, ID, NV and Yellowstone, WA, HI, AK- just for starters.

Don't think I missed this one either yesterday - but it is there now

Strange, I thought it said KIEV,00/LHZ and that I mentioned I was talking about the "the Marianas 6.3", but then again maybe be that was a different timeline?

Yes for a 6.7/6.9 I might agree but a 6.3? seems very small to be showing so much around the world. I must keep an eye on that.

So here is the same Russian recorder KIEV on the 16th August. KIEV.IU.00.LHZ.2010.228

On that day at 03:30 UTC there was a 6.3 in Mauritius. Do you see it?

Unfortunately the recorder stops about 18:00 UTC so there is no record of the 6.2 in Fiji at 19:35. So what about Greenland. Mm, this also has a problem at 18:00 ish but the 03:30 is not there either. SFJD.IU.00.LHZ.2010.228

On the 14th August there was a 6.3 at the Marianas - around where the first one I was querying is situated. Here is the plot from the same Greenland recorder. SFJD.IU.00.LHZ.2010.226 and here is Kiev KIEV.IU.00.LHZ.2010.226

I will let you into a secret, the quake was at 07:30.

Now here is the SHZ version. KIEV.IU.10.SHZ.2010.226 Can you see the 6.3 after 07:30?

Finally the Kermadec Islands: (about 4000 miles from the 6.3 on the 18th. KIEV is about 7000 miles+)
14th RAO.IU.10.BHZ.2010.226
16th RAO.IU.10.BHZ.2010.228

You can see the channels data for KIEV here and for Greenland here and the Kermadec Islands RAO here

I just think it is odd and I shall be watching them!

Edit: - to add distances.

That should be automatic. This is like the 3.2 the other day that was not automatically added.

Just what exactly is going on???????????????????????

reply to post by PuterMan


You lost me there, too many siesmos

I'm used to looking at the LISC ones, I find they are clearer (easier to read)
I know they are set up differently, our Karori LISC one rarely shows 4's here in New Zealand even if they are right under the hill the kit is sitting on, and even local 5's are just a small trace.

I spent a bit of time earlier in the year trying to match the Karori LISC graphs with the quake lists, some were obvious but I did see quite a few that no networks posted, it took a long time for USGS or GEOFON to find out where they were at, up to 2 weeks in some cases, most of them were in the Southern Ocean between NZ, Australia, French Polynesia on the Pacific/Antarctic Ridge.
Sometimes they never did report anything.

reply to post by Anmarie96


I agree with you. I have been re-visiting the lists today in between my other tasks, and I am noticing the same thing. The quake list here in Washington keeps growing. It seems to be taking a long time for them to get added.

And yeah, what about those automatic ones above 2.5 in the states? It leads me to think that EVERYTHING is now getting reviewed before being posted, which would ofcourse explain it. The next question would be why? Is it due to the recent (this past year) mistakes with a couple of major false alarms, or something more sinister? Although the movie 2012 was WAYYYYYY over the top, one point I agree with is how the government would handle it. If there was something major brewing, they would NOT want the general public to know about until they were ready for us to know about it. (this IS ATS so I gotta do it )

Edit to add: Along these same lines, making me wonder if there is a connection, the Deep Tremor Array updates have NOT been made yet today. In fact, there isn't even an update yet for yesterday, which seems quite odd. It seemed like they were ALL over it, and now.....NADA. Makes me a little uneasy.

In thier last post on the 17th, the mentioned it was slowing down a bit and moving south also. (which is weird) then, yesterday we had the wierd 'sonic booms' and no reports. I did find this graph, however which shows a very sharp spike late yesterday and now a steady increase today.

HERE


Add to that the four EQ's we have had so far today:

MAP 2.0 2010/08/19 20:52:56 47.324 -122.071 0.0 3 km ( 2 mi) ESE of Lake Morton-Berrydale, WA
MAP 1.5 2010/08/19 11:46:38 48.281 -124.590 0.0 10 km ( 6 mi) SSE of Neah Bay, WA
MAP 1.2 2010/08/19 08:46:03 47.529 -122.829 17.5 11 km ( 7 mi) SW of Erlands Point-Kitsap Lake, WA
MAP 2.2 2010/08/19 04:25:30 46.680 -122.372 13.7 15 km ( 10 mi) NNW of Morton, WA


...all of them are either on or near the peninsula. It would seem things are FAR from over.


Edit (again) to add: HERE is a link to the webicorder B001, which is showing the sharpest increase on the other linked chart. Looks quite active.
