For those of us who are idiots.....can you explain what you mean by a bulge in the lake and the potential danger a swarm there would pose?
I think I have an idea, but want to make sure. Thanks!
Not an expert.. But lakes usually form on the business end of a volcano over the "plug" where below is where the magma chamber is... Any bulge or deformation would indicate an upsurge of magma or disolved gasses to the surface causing the land on ground level to warp or bulge... In other words... Not good.edit on 6-1-2013 by EvanB because: (no reason given)edit on 6-1-2013 by EvanB because: magama??? wtf is that?? lol.. I hate me sometimes :-/

She didn't know about the potential of a superquake, and I didn't tell her (it's a scary thought if you don't yet have it in your personal universe). She's a long way from actually doing it. And I know, even if you live hundreds or thousands of miles away it will get you, but the thought of living right on top of it, naw.
no need to worry about location for this volcano, if it erupts everyone worldwide will be done for as it's well known as a possible extinction level event and the possibility isn't in the magnitude, it's in the likelihood of it erupting.
thanks OP for bringing this to our attention and that's why i love this place, so much information our anemic govt. and MSM will never tell us about.
This is not correct.
Firstly, Yellowstone can erupt with two quite different scenarios.
The first and more likely is a steam event. The lake bottom falls to pieces exposing the entire volume of water in the lake to lava and extreme temperatures and you have an explosion. The effect while catastrophic is localized.
The second is a volcanic eruption. Since Yellowstone is located within the Northern Hemisphere the resultant Volcanic Winter would be largely confined to the Northern Hemisphere.
This event can not be classed as an extinction level event since the Southern hemisphere would largely survive.

Folks, no question at all that this is seismicity. I've got spectro on it, and been at this way too long to confuse these signatures with anything BUT seismicity.
I have an email off to my contacts already, so let's see if I can bring you any more info.
I am hoping these aren't happening near the big bulge at the bottom of the Lake.
As usual, we are running a bit ahead of updates from the UoU:
They are not showing it yet, but it's a weekend, so probably tomorrow they will start backfilling the events.edit on Sun Jan 6th 2013 by TrueAmerican because: (no reason given)
Is there a bulge beneath the lake?
Mapping of the lake bottom has revealed a variety of faults, hot springs and craters beneath Yellowstone Lake. In a scientific report by Morgan et al., 2003, one feature was informally named the "inflated plain" by USGS researcher Lisa Morgan, who organized surveys of the lake beginning in 1999. In mapping the entire lake, she and her colleagues identified a region about 2,000 feet long that rises about 100 feet above the lake floor. The area is in the northern part of Yellowstone Lake, south-southwest of Storm Point. The area is home to many hot springs and the nearby sediments have undergone chemical changes (alteration) due to the flow of thermal water.
Why was it called the "inflated plain"?
Seismic images of the lake sediments in this area show that they were tilted, hinting that the region may have been pushed up or "inflated." The amount of inflation would be much less than the 100-foot height of the feature, but is currently unknown. The images appear to indicate that the uplift is associated with accumulation of gas from Yellowstone's hydrothermal (hot water) system. Similar inferred gas accumulations were also noted elsewhere within the lake. Future research will assess the amount of uplift and its origin, whether by gas buildup or other potential mechanisms.
Has the "inflated plain" been growing?
At present, there is no evidence of recent growth of any features beneath the lake, and there is no indication that residents or visitors are in any danger. Temperature measurements from hydrothermal vents taken this year indicate no change in temperatures compared to those taken last year. The feature may have been there for decades or much longer.
So what's the big deal?
There may be none. This region has active hydrothermal features, and possibly some uplift. It's possible that the area could host future hydrothermal explosions, but so could other areas beneath the lake and other areas within the Park.
