    Doomed are we!!!!!

    Anybody heard about this magma lake underneath Yellowstone Park in good old USA?

    Chatting to Onkar there seems to be a large build up of volcanic activity beneath the park and a super volcano may blow in the next year or so.

    So are we all doomed?

    Are the bloody yanks to blame, they seem to be for everything else in the world?

    How will we survive this, and where can we get some home defence things from?

    Could keep me up all night this.

    Well - obviously, we're all doomed in the long run. But I wouldn't worry overmuch about Yellowstone. For starters, there's nothing we can do about it, and secondly there's this:

    Yellowstone Lake Earthquake Swarm Summary as of 6 January 2009

    Through 5 January 2009, seismic activity has markedly decreased. It is possible that the swarm has ended, though a return of activity may occur as Yellowstone swarms of the size usually last for tens of days to many weeks.

    About 500 earthquakes occurred between Dec. 26 through Jan. 1. Three hundred of the earthquakes (including all >M2.0) have been reviewed by seismologists. There have been 86 earthquakes with M > 2.0 and 16 earthquakes > M3.0. About 200 smaller earthquakes have yet to be reviewed. Depths are difficult to determine accurately. The best located earthquakes have depths on the order of 3 to 10 km (1.8 to 6.0 miles). From Dec. 26 through Jan 2, the earthquake hypocenters appear to have migrated northwards, starting southeast of near Stevenson Island, with many of the latest events occurring near Fishing Bridge.

    The recent swarm is well above typical activity at Yellowstone. Nevertheless it is not unprecedented during the last 40 years of monitoring. Swarms are the typical mode of occurrence of earthquakes within the Yellowstone caldera, with magnitudes ranging to > 4.0. The 1985 swarm on the northwest rim of the caldera lasted for three months, with earthquakes up to M4.9 and over 3000 total events recorded.

    Magnitudes of earthquakes in this swarm range from zero to 3.9. Seismologists categorize those of magnitude less than 3.5 as generally not felt by persons. For perspective, earthquakes of magnitude 3.4 to 4.5 are often felt, as several of the events in this swarm have. A magnitude 5 or greater is generally required to produce damage to buildings or other structures.

    Improved volcano and seismic monitoring at Yellowstone gives us a greater ability to locate earthquakes, understand their source process and identify anomalous sources of seismic activity. New equipment including precise measurements of ground motion by GPS receivers and borehole strainmeters provided by the National Science Foundation's EarthScope and Continental Dynamics Program have been used extensively during the last week of intense earthquake activity. Ground motions accompanying the swarm, from the GPS instruments will take two or more weeks to fully process. It is worth noting that in 2004 the Yellowstone caldera began a period of accelerated uplift measured by GPS instruments that was as large as 7 cm/yr (2.7 inches/yr), three times as fast as recorded in the recorded history but has now reduced to about a maximum rate of 4 cm/yr. Scientists have modeled this deformation as due to magmatic recharge of the Yellowstone magma chamber at a depth of ~10 km (6 miles). The area of the swarm is on the eastern side of the uplift area.

    Earthquakes at Yellowstone are caused by a combination of geological factors including: 1) regional stress associated with normal faults (those where the valleys go down relative to the mountains) such as the nearby Teton and Hebgen Lake faults, 2) magmatic movements at depth (>7 kms or 4 miles), and 3) hydrothermal fluid activity caused as the groundwater system is heated to boiling by magmatic heat.

    At this time, no one has noted any anomalous changes in surface discharges (hot springs, gas output, etc.).

    YVO staff from the USGS, University of Utah and Yellowstone National Park continue to carefully review all data streams that are recorded in real-time. At this time, there is no reason to believe that magma has risen to a shallow level within the crust or that a volcanic eruption is likely. The USGS Volcano alert level for Yellowstone Volcano remains at Normal/Green.

    Yellowstone National Park is evaluating infrastructure near the north end of Yellowstone Lake to assess if any damage has occurred to facilities.

    Winter visitor activities and staff operations have not been impacted and continue as normal.

    -----
    The Yellowstone Volcano Observatory (YVO) is a partnership of the U.S. Geological Survey (USGS), Yellowstone National Park, and University of Utah to strengthen the long-term monitoring of volcanic and earthquake unrest in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.

    Cool Re: Doomed are we!!!!!

    Phew!! Thank God for that.. for a moment there I thought you said Jellystone National Park! I cannot imagine what would have become of Yogi and Boo Boo

    Although freakily enough Yogi and Boo Boo featured in a instructional cartoon called Yogi's Quakey Shakey Van which told people how best to behave in case of an earthquake! Is there a better example of life imitating art?







    Well, apart from the fact that a huge volcanic explosion is not an earthquake (but it may cause one)

    You'll be alright surely?

    You just send your good lady out with her new Christmas toy to catch your dinner, while you sit keeping the home magma burning.

    Well due to the cold weather all work has been suspended this week so I am at home making my own arrows.

    Getting the hang of it now and have a large number of fully varnished and waterproof home made arrows which are kind of deadly really.

    Me and the Bat are doing an Archery course at the end of the month, which will give us our licenses and enable us to join a local club.

    Quite looking forward to the end of the world now pips.

    I'm having a disturbing vision of DTS standing on his scaffolding tower facing the "end of the world" with his bow and arrow and saying "go ahead, make my day".

    Unfortunately for me the most disturbing bit of my vision is that DTS is wearing some kind of stone-age thong and nothing else

    In my experience, it's the voices telling you to burn things that are the most fun to listen to. Plus, you get to stay a little warmer in that chilly winter you're having
