YELLOWSTONE VOLCANO OBSERVATORY INFORMATION STATEMENT
Wednesday, February 3, 2010 11:22 AM MST (Wednesday, February 3, 2010 1822 UTC)

Yellowstone Volcano
44°25'48" N 110°40'12" W, Summit Elevation 9203 ft (2805 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN

An earthquake swarm continues on the northwest edge of Yellowstone Caldera. There is still no indication of premonitory volcanic or hydrothermal activity. As such, the Volcanic Alert Level remains at Normal (Aviation Color Code of Green).

A daily update about the swarm can be found at: http://volcano.wr.usgs.gov/yvo/publications/2010/10swarm.php.

PRESS RELEASE FROM YVO PARTNER UNIVERSITY OF UTAH SEISMOGRAPH STATIONS

Press Release

University of Utah Seismograph Stations

Released: February 03, 2010 10AM MST

This release is a continuation of information updates building upon our five previous press releases on the ongoing earthquake swarm on the west side of Yellowstone National Park.

The University of Utah Seismograph Stations reports that a period of increased seismic activity occurred on February 2, 2010 beginning at ~3:30 PM MST. This period of increased activity lasted about 6 hours and included at least 2 events that were reported felt in Yellowstone National Park. The two largest earthquakes during this sequence were magnitude 3.1 and 2.8 that occurred at 7:31 PM and 7:44 PM respectively.

These earthquakes are part of an ongoing swarm in Yellowstone National Park that began January 17, 2010 (1:00 PM MST). The largest earthquake in the swarm as of 7 AM MST, February 03, 2010, has been a magnitude 3.8. There have been 1,719 located earthquakes in the swarm of magnitude 0.3 to 3.8. This includes 14 events of magnitude larger than 3, with 135 events of magnitude 2 to 3, and 1,570 events of magnitude less than 2. There have been multiple personal reports of ground shaking from observers inside the Park and in surrounding areas for some of the larger events (for felt reports, please visit http://earthquake.usgs.gov/eqcenter/dyfi/). Earthquake swarms are relatively common in Yellowstone.

Yellowstone Volcano Observatory scientists still consider that the swarm events are likely the result of slip on pre-existing faults and are not thought to be caused by underground movement of magma. Currently there is no indication of premonitory volcanic or hydrothermal activity, but ongoing observations and analyses will continue to evaluate these different sources.

Seismic information on the earthquake can be viewed at the University of Utah Seismograph Stations: http://www.seis.utah.edu/.

Seismograph recordings from stations of the Yellowstone seismograph network can be viewed online at: http://quake.utah.edu/helicorder/yell_webi.htm.

Anyone who has felt earthquakes in the swarm are encouraged to fill out a form on the USGS Community Felt reports web site: http://earthquake.usgs.gov/eqcenter/dyfi/.

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.

The earthquake swarm on the northwest edge of Yellowstone Caldera continues. Since about 2200 UTC (1500 MST), the level of activity has increased, with 12 earthquakes >M1.5 recorded. Many more smaller events have been detected and will be quantified by analysts in the near future. The larger events continue to be felt in the Old Faithful area of Yellowstone National Park.

Over 1800 earthquakes have now been recorded since January 17, 2010, making this swarm longer (in time) and with more earthquakes than last year's swarm beneath Yellowstone Lake (December '08/January '09).

Curiousity eventually lead some to understand that the world wasn't flat, the rest were just a day late and a dollar short ;)

What is the point? Spamming YouNews with this drivel.

21:07 seismic systems are up and running.

JY says ... on Thursday, Feb 4 at 8:02 PM

I know the real reason behind it, tell you in the morning.

lee98632 says ... on Thursday, Feb 4 at 7:14 PM

YMR is down and out . 18:56

JY says ... on Thursday, Feb 4 at 10:08 AM

WOW! YMR delay! And webcam goes "?", all other seismic monitors ahead!!!! Are they messing with us? Some people came to sit and watch, so if they are gone it's because they Rannnnnnn! Omg, bigbrother is watching OUR moves too..the nerve!

Use YWS live webcam to see quakes.. says ... on Thursday, Feb 4 at 9:00 AM

Not sure once this word gets out if the live webcam at Yellowstone will stay up and running after I post this but. Go to YWS webpage. click on live webcam. you can see the quakes as the camera moves up and down in response to the ground moving.

http://www.seis.utah.edu/helicorder/yell_webi.htm YFT is Old Faithful, take a look at the rest. YMR has the most.

JY says ... on Thursday, Feb 4 at 8:30 AM

OK, YFT is offline, but I may have found a way around it. If you over lap the other yellowstone sites together, you will find an echo of the seismic activity surrounding Old Faithful and possibly the direction of least resistance for waves to travel.

That's not all, they failed to update the list. There have been true quakes but the staff at Yellowstone has not reported them.

JY says ... on Wednesday, Feb 3 at 7:49 PM

Good eye! I wish they would give access to that area, it's "off-line". I'm grabbing my pack and goin-in-007style!

JY says ... on Wednesday, Feb 3 at 7:45 PM

OMG all facts are screwed up lol!
