Whats going on at yellowstone?

Another Utah quake, in addition to that 2.9 this morning. Now a 3.2, further South:

For the purpose of watching the current action, I recommend a different map than the standard Yellowstone view:

earthquake.usgs.gov...

or the Intermountain West map

www.seis.utah.edu...

Current activity is definitely more dispersed than was the case in the early 2010 swarm.

Edited to add: not to attract the end times folks but weren't we told it would be more worrisome if we saw activity all around the caldera?

It wasn't just me, a few of you could see something brewing. There's a definate pattern to the activity. It starts slow with a few hiccups, and then, like you say, boom, boom, boom.

Yeah, what's really interesting to me about it this time was the way it was preceded by action all over the intermountain west. Hopefully this is all there will be but I've got a hunch it isn't. (And by saying that everything will calm down, right?)

Does anybody else think it really looks like two rapid-fire quakes?

www.iris.edu...

I'm betting it will turn into 2 downgraded quakes, second one bigger than the first.

reply to post by quakewatcher


Well I can't argue with you connecting the activity in the region. In the article I posted with Bob Smith, it said the mountians are part of the same general tectonic zone, and that there may be magma moving under the region.

Nothing weird about this. Yellowstone is the largest on this planet. When the earth and sun ++ is changing its natural for the yellowstone to react. We just dont hope it will burst out. Scientists have the answer yes,but the info will not be informed.

Ok, I dont typically post here because there is not much that you could post that would shock me to be honest.

THAT is weird. That is not normal. I just cheked a few other things out and there is weird all over the place right now. Check out the RSOE site, the amount of volcanos that are having minor quakes today is far beyond eyebrow raising. There was something big that hit Massachusetts today judging from the live internet seismic servers, and now i am reading reports that they had some freak fire in their subways late last night that hurt some 20 people.

Meh. That's the oldest subway line in America, it has problems all the time.

What're you talking about re: seismicity in MA?

Does anybody know if there's a map of the magma plume with surface towns on it?

This is the plume

news.nationalgeographic.com...

the current pattern of quakes in Idaho, Montana and the park seem to roughly correspond to the surface edges of the plume, but I could be wrong.

earthquake map:
earthquake.usgs.gov...

Anyway, it would be good to have a map for future reference.

yes beeing following it a while...very weird...
RSOE vulcano's section is updated i saw... interresting !
preccesion time volcano's...hihi

Lake Taupo 8 Australia & New-Zealand New Zealand North Island ~26,500 years ago
Laacher See 7 Europe Germany Rhineland-Palatinate ~12,900 years ago
Kikai Caldera 7 Asia Japan Osumi Islands, Kagoshima Prefecture ~6,300 years ago
on 1 time preccesion.(26.500 yrs). 1/2 time .....quarter time
and not listed at RSOE VEI 7 caldera Santorini/Thera greece last erupted 3500 years ago at 1/8 time...

coincidense?.. think NOT.... there seems to be an line in all big events...

I see by the seismograph light eruptions.

To be more earthquakes around the caldera

is this normal?

or possibly even a tremor? As this small earthquakes can be seen throughout the park ...

Since then it starts to pop soon?

It's not abnormal for Yellowstone, lately anyway. I'd say it's more "interesting" for now. The fact that the EQ's are scattered all around the hotspot rather than in one small area as they have been in the past couple of swarms is interesting.

In the past couple of years however, we've seen significantly more activity than what we are looking at today. In the past, quite large earthquakes have been recorded there (google Hegben Lake earthquake) without anything of note happening at the volcano.

Of course, I wouldn't be obsessing over it if weren't a supervolcano.

teleseism coming in from the 6.3 between Kamchatka and Alaska.

You'll see something very dramatic on the seismos but I think that's all it is.

Just a tiny little thing to add...

I live in Boise, ID. A couple week ago to the day we actually had a 4.9 hit near the border. Not exactly a small earthquake for this region (comparatively, of course).

www.abovetopsecret.com...

PB207 is showing quite a bit of microseismicity again, for the past hour or so.

www.iris.edu...

in about an hour you'll want to switch to this link, for tomorrow UTC

www.iris.edu...

Showing up well on the Moose Creek webicorder so it may be centered to the Southwest, in Idaho.

www.seis.utah.edu...

Still too small to show up on the earthquake map.

All stations in the Tetons are down, at least they are on the web. Does anyone know how long this has been the case?

Can anybody get the raw data, or are they truly down?

I thought it was interesting that if you look at the earthquake map there are definite lines going out from the center at the park, into Idaho and into Montana, but not one to the Southeast into the Tetons, although you can see where one starts in the Southeast end of the park, and where there is activity further South in Utah. (Which may or may not be related) Now I wonder if those stations are just down. Would the other stations be able to pick up a 1.x in the Tetons?

Edited to add: as further proof that I'm not crazy (about this, at least) check out this animation:

quake.utah.edu...

keeping in mind the red lines I drew on the map, notice how on multiple occasions nearly simultaneous quakes occur along one of the lines, with the center of the action being Yellowstone.

They were down about an hour ago when I checked and are still down for me.

The broad band instruments at the teton stations seem to be OK and
can be looked at with Bud Explorer on the IW network. Here are some
examples:
