They must share a back end with the 30Gb Zunes :)

You may have solved it, 41magsnub. But that information must be suppressed if it deflects blame from fistful.

The Capital Commerce columnist at U.S. News has an interesting story here. It contains a lengthy email exchange with a scientist at the U.S. Geological Survey, Yellowstone Volcano Observatory.

I find it curious that more coverage is coming from folks like this than news reporters in the MSM. I guess it's a non-story at this point. Perhaps it's just not salicious enough.

C'mon people, is the Lava Lake thing possible?

Are there lava lakes anywhere else in the world?

I don't think there are... ergo it isn't possible. You would shed heat too quickly for the lava to remain [dr. evil accent] molten magma [/dr. evil accent]. It would crust over, turn to rock, and seal the flow so that pressure could build again.

There may be some small lava vents on the deepest parts of the sea floor, but those are a heck of a lot closer to the [evil] magma [/evil] flows.

I don't think we'll get a puddle of liquid rock in place of Yellowstone Lake.

No lava lakes in the world? Uh, remember the Kilauea volcano in Hawaii?

Very well, I sit corrected.

IIRC, not at Yellowstone, unfortunately. I believe that whatever tells the geologists these things, the heat and pressure of the "hotspot", the mineral makeup of the magma, dissolved gasses in it etc., explodes it into ash instantly on contact with regular air pressure. Which also means there's no fancy high-tech way to slowly release the hotspot, like drilling and nukes etc. either.

It's like having 300 degree liquid superheated water in a pressure bottle then opening it up.

There might be a magma lake at the end of the eruption, but there won't be anyone around to see it. Perhaps it would be imaged from satellites controlled from other continents.

Pyroclastic flow with roidrage.
From the History channel some years ago I remember that the caldera changes with the tectonic plate movement. The current pos where all these tremors are located may be the western edge of the next kick.

There are some pretty neat lava lakes in Africa, too, IIRC, near the rift zone.

Lava Lake at Mount Nyiragongo.

Silica is pretty much it. High silica content produces high viscosity lava and carries a lot of other mineral content. This produces tall volcanoes and pyroclastic flows. Cooler lava, but bigger messes. Think Mt. Saint Helens.

Low silica content produces low-viscosity lava that flows easily. There is usually no tall feature to the volcano. Think Hawaii.

Water vapor influences the violence of the eruption. A sudden release of pressure causes the trapped vapor to expand, and the volcano blows its top, to the tune of gigatons, sometimes. No water vapor, no boom.

Usually we hear about high-silica, high-water vapor volcanoes because they're big and nasty, but there are violent low-viscostiy events, and quiet smoky ones, too.

Certain mixes of gas and silica are produced by certain types of hotspots, so a plume gives us a hot but quiet extrusion, and subduction gives us cooler but more explosive events.

At least that's how I remember it. Apologies to Mrs. Boldt if I'm wrong.

Hey, it stopped.

Is that like it stopped as in it stopped, or stopped as like when they stop shooting just before the bomb?

"Ruh, roh."

There still appears to be some activity, but it has slowed quite a bit. We wait and see...

The latest and greatest from the USGS:

YELLOWSTONE VOLCANO OBSERVATORY INFORMATION RELEASE

YELLOWSTONE VOLCANO (CAVW#1205-01-)

Yellowstone Lake Earthquake Swarm Update: 2 January 2008

The University of Utah Seismograph Stations reports that as of 1800 MST on 2 January 2009, seismicity of the ongoing Yellowstone earthquake swarm continues. Over 500 earthquakes, as large as M 3.9, have been recorded by an automated earthquake system since the inception of this unusual earthquake sequence that began Dec. 27, 2008. More than 300 of these events have been reviewed and evaluated by seismic analysts. Depths of the earthquakes range from ~ 1km to around 10 km. We note that the earthquakes extend northward from central Yellowstone Lake for ~10 km toward the Fishing Bridge area, with a migration of recent earthquakes toward the north. Some of the dozen M3+ earthquakes were felt in the Lake, Grant Village and Old Faithful areas. Personnel of the Yellowstone Volcano Observatory continue to evaluate this earthquake sequence and will provide information to the NPS, USGS and the public as it evolves.

From what I've read, there is little connection between distant events.

Common pool of magma and the mantle is not divided as tectonic plates are.
Could be a gravitation anomaly on some unseen or noted mass within an astronomical units reach of earth. That would stir the still hot nuclear core and cause a wiggle of the earths center of gravity.
