Something Stirring at Mount Saint Helens - 2/14/1011

Seeing as how a large quake that just hit at Mount Saint Helens has been upgraded to 4.3, I am feeling this warrants its own thread. I don't want anyone to miss anything on this!!!


Here is the latest:

No, this does not include the ones from today. As you can see, there haven't been any larger than 1.9 for the past month. We rarely see anything over 2.0 or 2.5


looking HERE there also appear to be several smaller ones too. I am going to pull up GEE and try to watch all this live.


I will keep you updated on any new quakes or news!!!

Good job westcoast I have a Granddaughter and son in the Cal. Bay area and Shasta regions. Please keep us informed.

Our local Seattle news station is already running a story on it: (although they haven't updated the magnetude in their article yet....a little slower than ATS.

3.3 and 2.5 magnitude earthquakes shake Mount St. Helens area

Some people in the Mount St. Helens area felt a little shaking Monday morning after two small quakes struck the area

There were no immediate reports of injuries or damage.

I truly believe the U.S. Government knows something BIG is about to happen here in the U.S. I can't say they are to blame because I don't have any hard facts..It's just my gut feeling though that they are behind it all. I want to see what happens with all the mre's, blankets, fast set-up housing , etc...that they have just ordered and being sent around the region where their so-called drill is suppose to take place in May of this year....If these volcanos keep acting up they may have to use this stuff before then....It seems now that 2x a week the whole earth is shaking as you can see on the live internet seismic server.Anyway, we can only wait and see. If anything does take place, and they are responsible, let's hope they are the ones that get hurt and not us......

Here is link to seismic server:aslwww.cr.usgs.gov...

Looks like the earth is shaking it self to death today also.........

Hi Westcoast, I posted on your other thread but as you've got this one up and running for this quake then I'll comment here as well.

A query for you: how's your dog now? Is she still acting scared as she was yesterday?

Mike

Good question!!! A few hours ago, while my daughter was getting ready for school, I commented on how she was scared and shaking again. We had a brief conversation about whether or not there had been a quake the other day. (there was one near Rockport...about 20-30 miles from my house)

Even my kids and husband are becoming convinced there is something to her EQ sense.

We are quite a distance from Helens, (over 100 miles) so I am actually a bit surprised that she DID seem to be acting funny this morning. Although 4.3 is NOT a small quake...especially for here. It was very shallow though....which makes me think it is definately volcanic in nature.


I want to also stress that by starting this thread I am not implying that I think it is errupting...just this is abnormal, and I want to keep everyone informed on what is going on, just in case it starts to look like it might errupt.

Just been another one... Noticed it on the webis and it's just come up on USGS:

According to THIS, looks like an other quake just hit. Perhaps in the 2.0 range. Waiting for PNSN or USGS to update.


EDIT to add: HA! Thanks JustMike....at least my guess was close.

reply to post by westcoast

Yes, a 4.3 is significant in that area: they're far from common! And as you say, it doesn't have to mean anything major is imminent but all the same it's good to have it logged.

Most interesting that your dog was showing her signs of nervousness yesterday (and also good that you logged that in the other thread at the time). It helps to lend credence to the hypothesis that some animals are very sensitive to such things.

Okay I'm off to dinner (it's nearly 9 pm here). Be back later...

Mike

EDIT: won't surprise me if they downgrade that 2.3 a point or two after seismologists review it.

reply to post by westcoast


The 4.3 was a double.
B201.PB..EHZ.2011.045

That is not the 2.3 as that is an hour later

You know if you look at that seismo it looks like a 4.3, then a 3.3 (the two green ones) followed by the 2.3 (black)

reply to post by JustMike


They won't Mike. Look at the seismo. That is what it says it is, if you get me.

reply to post by PuterMan


Yup...back to back.

I have GEE up, looking at the nearest stations. I cant pull up Helens though because GEE is still not working right. errrrrr......

Here is a screen shot with the latest quake:








@Puterman: At that depth, etc. do you think it tectonic or possibly magmatic? Or is it impossible to tell? Could you tell by listening to it?

reply to post by westcoast


Looking even closer at that I am reading 4+,

reply to post by PuterMan


Cool...thanks so much. I agree, there are a whole bunch of micro quakes surrounding the bigger events. I found this seismo that is set really high, so it has a nice clean image of these quakes:






(looking forward to hearing it)

thought i felt it..
but its rather far away from me

looking at this webicorder
www.pnsn.org...

got the feeling...
the first blue EQ someting broke..
then the thick lines: something flueing..(magma ?)
then the big ones when it definite cracks....

perhaps comparing with the 1980 eruption charts?

Maybe this is the cause for that "rumble" about wich some ATS-ers talked about and even recorded on cam!
This could be "the calm before the storm"!
Tommorow 15.02.2011 the solar storm will hit earth !
YES , IT SHOULD BECOME "INTERESTING"...

reply to post by ressiv


Well, I don't know enough about magmatic movement to make an intelligent response to that...but I have to admit I was thinking along similar lines.

I am skipping from seismo to seismo to look for anything like the dreaded HT word. (harmonic tremor) If these quakese ARE the precursser to magma moving around or up, than we should see some HT I would think. Perhaps not right away.....I will be keep watching, that's for sure!

Also of note...on one of my other threads, there was a paper that mentioned the possibility of Helens and Glacier Peak sharing the same magma source. Hmmm....something else to watch.

Well, I have a huge thread devoted to just that, so you better believe that I am always thinking along those lines.

I am already planning on paying very close attention to the 'rumble' when the latest wave from the CME hits.

has the time of the CME been announced?
