THE SOURCE

Odd you know - we had a rushed 'Briefing" from NASA on the 30th with a bunch of nervous Nellie's who said nothing really - hours latered followed by a comet slamming into the sun creating a massive "CME" out the opposite side of the sun in time to impact. All makes me shake my head and say pour me another on Sam....

Check This out.

Wonder what effect if any there will be.

Well,Robin ,thank you.
I'm feeling a little loony also.
Revolution on the brain.

I digress.
Yes,a combination of factors,with the stress of some rocks just getting ready to burst in the form of an earthquake,plays into it all.
And some places are over due.
Just depends on how much the combination of factors will break it all loose.

and never seem one near Bermuda before. Thats diverse.

Perception and reality do not always go hand in hand. Maybe it us due for another 1975 style swarm?

Not 18 minutes apart. That would be unusual.

It was 2 quakes. BBSR.IU.10.BH2.2011.276

Ah well my mistake, thank you. I was a bit busy at the time and had only glanced at the map and magnitude and assumed it was a double read.

reply to post by PuterMan


Where on USGS do you find this list Puterman?? It is diffferent than that of the maps/historical link. It does not surprise me you know that site left and right ...please tell your "students" how to obtain this as you did.

Just waking up, pull up the USGS, things are starting to look rather active this morning. Don't mind me, haven't had coffee yet.

That is what I was thinking as well. Today may indeed be an active day....although we know they take a long lunch break....so who knows.

I am only on my second cup of coffee so I am a little ahead but still time to catch up Summer.

Yep, and when you take lunch let me know, then I know I can go get a few things done and I wont miss a thing

reply to post by kdog1982


Kdog, that's the same theory being researced in the February 6, 2009 Sichaun quake--that the weight of the dam (and water) caused the quake (and the ensuing massive loss of life):

mobile2.wsj.com...://online.wsj.com/article/SB123391567210056475.html?

I don't understand so much of geology, but the simplicity of adding (or subtracting) massive weight from the earth's surface (crust) makes sense.

And #robin marks...I agree too on the "loony moony" effects...sometimes you can 'feel' something is out of the norm.

It is just a simple circular search. Nothing magical. I think I gave the instructions a while back.

Click circular area search

earthquake.usgs.gov...

I will try and find the images I made up. - found it

[atsimg]http://files.abovetopsecret.com/images/member/ded36996ef86.png[/atsimg]

Remember this www.abovetopsecret.com... ?

I emailed the USGS, and I emailed them again because they did not respond. It sort of went

You have it as 4.5mb and sorry but I may not be a seismologist but a 4.5mb cannot be a 6.9 in whatever your other column is. neic.usgs.gov... is the web page for the quake, but there is no phase data and no tensor solution. There is also no shake map for it, nor any PAGER reference. Basically this quake was as JMO says - a 4.6 and this 6.9 on the web site is an error and should be removed.

I got an email today saying they would fix it and and if you click the link in the quote you will see it has been fixed.

Result!!

Some activity at Katla it seems.

This was last night



and this is this morning



I think we may have a problem Houston.

ETA: Added the SNB graph here. Looks as if there is tremor starting. We may see an eruption in the next couple of days if this carries on.

IT IS OFFICIAL. PuterMan is a doddery old fool.

My sincere apologies to all and sundry for an unforgivable error on my part when listing Bermuda. I am normally very careful about these things, but I missed the - (minus) sign off the longitude. Bermuda is of course WEST and not EAST,

My list was actually on the border between Afghanistan and Pakistan in a fairly remote area.

Perception and reality are the same in this case!

My thank to jjjtir for pointing out my stupidity.

reply to post by PuterMan


Oh I am so relieved I was beginning to think you were not human as you never seem to error. You do such a brilliant job here so thank you

reply to post by PuterMan

Doddery old fool, my eye! You are the man who wrote to the USGS/NEIC to tell them they had a quake listed at entirely the wrong magnitude -- and a bunch of professional seismologists found that a glaring error had slipped them by and after your message they saw that you were right -- and fixed their error!

Seriously though, we appreciate your dedication, insight and plain-spoken honesty, Puterman! No-one is perfect and a very rare slip-up like the one you made (but then corrected!) is both understandable and quite forgiveable.

You're all right by me.

Best regards,

Pretty shallow quake, that one. Hmmm... Considering how close it is to Guy, possibly linked to fracking?

Mike

this is a copy of what i wrote on the Arkansas thread...

There have been four quakes over night in Arkansas. Mostly near Quitman. I don't know what to say.Or rather, don't want to say what I really believe. I had really hoped that this story was over. The injection wells closed. The Guy/Greenbrier swarm ended. But the damage has already been done. Every day I watch the siesmos in Arkansas. Because. Because I know they are continuing to frack, and they are continuing to disposal injection outside of the exclusion zone. The entire area is seismic.

In my humble, non-expert opinion, the sequence of events are leading to a major earthquake. Just like 1811-1812.
It should be evident that Quitman is north of Guy and it may be that the Guy/Greenbrier fault extends to Quitman. One of last night's quakes was in Guy.

I actually think it's an artificial fault (meaning man-made) created by the injections. The fault could rupture from Guy to Quitman. If this is the case. We are in for another swarm. With larger earthquakes to follow.

I know one of my recent posts were extreme and seem over the top. But it's wasn't. I w

I knew I was right. Those damned Ohio quakes weren't natural. Once again. It's man made.

Forgive me if my observation is wrong and or laughable.

It seems to me that the swarms and volcanic eruptions resemble events a couple of hundred years ago when in concert, volcanic activity and EQ's were perhaps devastating to the US. This observation is not to place fear in anyone.....just being honest.

Again, I may be totally off and or wrong but it seems as though activity in regards to EQ's and Volcanoes may indeed get interesting.

New Madrid, California, and other areas in the US seem pretty vulnerable considering all the swarms and volcanic activity. Time will most definitely tell. In the mean time though...I am remaining alert and will be taking notes from all you guys and relying on your expertise to guide.
