Yellowstone Caldera -

From Wikipedia, the free encyclopedia

The Yellowstone Caldera is the volcanic caldera and supervolcano located in Yellowstone National Park in the United States, sometimes referred to as the Yellowstone Supervolcano. The caldera is located in the northwest corner of Wyoming, in which the vast majority of the park is contained. The major features of the caldera measure about 34 by 45 miles (55 by 72 km).[3] The caldera formed during the last of three supereruptions over the past 2.1 million years. First came the Huckleberry Ridge eruption 2.1 million years ago, which created the Island Park Caldera and the Huckleberry Ridge Tuff. Next came the Mesa Falls eruption 1.3 million years ago, which created the Henry's Fork Caldera and the Mesa Falls Tuff. Finally came the Lava Creek eruption 640,000 years ago, which created the Yellowstone Caldera and the Lava Creek Tuff.

Hot Spot: Yellowstone Road Melts, Sites Closed - CHEYENNE, Wyo. - Jul 10, 2014, 4:12 PM ET The ever-changing thermal geology of Yellowstone National Park has created a hot spot that melted an asphalt road and closed access to popular geysers and other attractions at the height of tourist season, officials said Thursday. The damage to Firehole Lake Drive is unusually severe and could take several days to fix. The 3.3-mile loop six miles north of Old Faithful takes visitors past Great Fountain Geyser, White Dome Geyser and Firehole Lake.

More developments are taking place at the Yellowstone Super Volcano. The kind of developments that were seen shortly before other volcanic eruptions. There has been a rise in the ground under Yellowstone lake. Readings of very large amounts of gases called Hydrogen Sulphide and Sulpher Dioxide are being detected. When these gases were detected at other volcanoes, it appeared shortly before major eruptions of those volcanoes.

Is Yellowstone about to erupt phone call with an employee at Yellowstone

Yellowstone Earthquake Swarms - More seismic unrest reported at Yellowstone: Seismographs have picked up a swarm of earthquakes in the northwestern corner of Yellowstone National Park, including dozens early Tuesday. The University of Utah Seismograph Station reported five small earthquakes including those with magnitudes of 3.4, 2.7 and 3.2 in a 20-minute period starting at 3:33 a.m. in an area 16 to 18 miles south of Gardiner. Earthquake information specialist Paul Roberson said there were another 20 to 30 small quakes Tuesday morning that hadn't yet been posted on the university's website. He called it a fairly normal swarm for Yellowstone. He didn't expect there to be any damage. Seismographs recorded 31 quakes in the same area south of Gardiner on Saturday, while another 23 were reported last Wednesday and Thursday in an area between 18 and 19 miles east-southeast of West Yellowstone.

U.S. Gov't Quietly Soliciting Other Countries To House Americans If Yellowstone Super-Volcano Erupts!

April 4, 2014 -- (TRN) -- The United States government believes the Yellowstone Super-Volcano WILL erupt within the next ten years and has been offering to pay foreign countries $10 Billion a year for ten years if they agree to house Americans on an emergency basis if Yellowstone erupts.  Dr. Jean-Philippe Perrillat of the National Centre for Scientific Research in Grenoble, France confirms the magma build-up and ten year time-line!

Yellowstone's Volcano and Earthquake a Cataclysmic Mixture?

Tuesday, 01 Apr 2014 - The magnitude 4.8 earthquake that struck Yellowstone National Park on Sunday was the park's biggest since 1980, and prompted many to speculate whether such a quake could trigger the ancient super-volcano living just underneath. In December, BBC News reported that scientists found that the super-volcano ­ also known as a "caldera" ­ was 2.5 times larger than previously thought, and could therefore threaten the entire globe were it to erupt. In total, its magma chamber is now thought to stretch 55 miles and contain 120-370 cubic miles of molten lava. The caldera's last cataclysmic eruption occurred 2.1 million years ago, and was at least 25,000 times larger than the 1980 Mount St. Helen's eruption in Washington state that killed 57 and destroyed 150 square miles of forest. According to Reuters, geological evidence shows that the super-eruption covered half of North America in ash, and killed animals as far away as Nebraska.

Yellowstone National Park Hit By Magnitude 4.8 Earthquake

March 30 (Reuters) - Yellowstone National Park, which sits atop one of the world's largest super-volcanoes, was struck on Sunday by a magnitude 4.8 earthquake, the biggest recorded there since February 1980, but no damage or injuries were immediately reported. The tremor, a relatively light event by seismic standards, struck the northwest corner of the park and capped a flurry of smaller quakes at Yellowstone since Thursday, geologists at the University of Utah Seismograph Stations said in a statement. The latest earthquake struck at 6:34 a.m. near the Norris Geyser Basin and was felt about 23 miles (37 km) away in two small Montana towns adjacent to year-around entrances to the park - Gardiner and West Yellowstone.

Earthquake at Yellowstone Caldera is No Need for Concern

Monday, 03.31.14  - Over the weekend, the Yellowstone National Park felt its strongest earthquake since 1980 - a M4.7 event located just north of the Norris Geyser Basin at a depth of ~7 km. As you can guess, with such an earthquake, the Yellowstone-fearing throngs got a little nervous. However, this earthquake is nothing out of the ordinary for Yellowstone, even if it is larger than your average seismic event in or near the caldera. Over the past few hundred years, the caldera has felt numerous large earthquakes, including a M7.3 earthquake in 1959 and none of them have led to an eruption at Yellowstone (even a small one). In fact, if you really want to be worried about hazards from Yellowstones, earthquakes might be the bigger danger. Sunday's earthquake did not have the right focal mechanism to be directly related to magma moving below the surface either. You would expect if an earthquake was being caused by magma working its way upwards and making room for itself in the crust that any earthquake that were to occur would be one caused by extension. However, the recent M4.7 earthquake had a focal mechanism that suggests it was mainly reverse (compressional) with a smidge of strike-slip (side-by-side) motion - not what you would expect for magma moving upwards leading to an eruption. The area that the earthquake occurred is a region of uplift in the caldera and exactly why this uplift is occurring is still being researched.

Warning signs that Yellowstone may Erupt

Posted by Joe For America on Feb 27, 2014 - Some worrying developments are taking place at the Super Volcano located beneath Yellowstone National Park; the kind of developments that were seen shortly before other volcanoes erupted.  Not only was there a sudden rise in the elevation of the ground, and development of new cracks, but a gas called Helium-4, a very rare type of Helium, has begun coming out of the surface.  It is the presence of this gas that has scientists quite concerned.  If the Yellowstone Super Volcano were to erupt, it would be 2,000 times bigger than the eruption of Mount St. Helens in the 1980?s.  Everything within 500 miles would be dead or destroyed within minutes, 2/3rds of the entire United States would be covered in volcanic ash and the climate of the entire planet would cool within a month.  On top of that, just this past week, the largest earthquake in the US took place just a few miles from Yellowstone proving hot magma is on the move.  Here's what has scientists concerned: Since late summer 2013, the Yellowstone GPS network has tracked a small " ground deformation episode" in north-central Yellowstone National Park. During the past five months, the NRWY GPS station has recorded about 3.5 cm (1.4 in) of uplift (the ground is rising) and about 1 cm (0.4 in) of southeastward ground movement, relative to a stable reference station north of the Park. Measurements from other GPS stations in northern Yellowstone show smaller displacements, forming a circular pattern of deformation (circular - as in the round mouth of a volcano) consistent with a minor pressurization (building-up underground), about 6 to 10 km (4-6 miles) deep, near Norris Junction. What has scientists very concerned is that Yellowstone has suddenly begun emitting massive amounts of Helium-4.  Helium-4 seems to be the predictor of activity, as proved with other volcanos.

UPDATED Feb. 5 *** INDICATIONS OF SEVERE EARTHQUAKE / ERUPTION AT YELLOWSTONE NATIONAL PARK

February 2, 2014 -- (TRN) -- A seismometer inside a borehole at Yellowstone National Park has begun reporting staggering underground activity near the southwest corner of Yellowstone Lake, possibly signaling the beginning of an eruption of the Super Volcano at the Yellowstone National Park. TRN has obtained the image of the Seismograph report and now YOU can see it for yourself!  This could be very nasty. . Yellowstone lake is pretty much the center of what is the Yellowstone Caldera; the mouth of a massive Super Volcano, located beneath the park.

 The activity began around 12:00 Noon, Mountain Standard Time (MST) on February 1, and was detected by a seismometer in Borehole B944 then continued, non-stop, all day yesterday getting worse and worse as the hours wore on.  The activity is continuing right now at 6:06 EST AM as this news article is being produced.

Yellowstone Park Sees Incredible Earthquake Swarm

Jan 7, 2009 11:48 AM - By Megan Boatwright, Local News 8 Reporter - Some pretty interesting things have been happening at Yellowstone National Park since December 26th.  Over the last week geologists have recorded more than 400 small earthquakes.  Quakes in that number are called an earthquake swarm. The incredibly long list represents 400 or more earthquakes that have happened under the lake.    "We think it's where more magma heat and steam escaped through cracks in the crust," said Clayton.  "That's probably what's causing the earthquakes."  He said the last time Yellowstone saw this kind of activity was close to twenty years ago, "What's interesting about this earthquake swarm is that it's in a very large and active volcano." "It's probably a little bit of magma moving through fractures.  There's also a lot of ground water under Yellowstone and some of the shallower earthquakes may be steam explosions and fractures underground,' said Clayton.  "Those can have quite a force, and send out shock waves that we record as earthquakes."

Quake Swarm Hits Yellowstone; Something Bigger to Come?

Small Earthquake Swarm on 9 January 2009 near northeast corner of Yellowstone Caldera: A currently modest swarm of earthquakes began in the northeast corner of the Yellowstone Caldera, about 10 miles (16 km) NNE of the north end of the Yellowstone Lake swarm that was active in late December and early January. As of 1930 MST, 10 earthquakes had been located by the University of Utah Seismograph Stations, the largest with M= 3.3 and two other events with M >2.0. Located depths are between 2 and 4 km.

December 30, 2008: Yellowstone National Park was jostled by a host of small earthquakes for a third straight day Monday, and scientists watched closely to see whether the more than 250 tremors were a sign of something bigger to come. Swarms of small earthquakes happen frequently in Yellowstone, located in Wyoming in the western U.S., but it's very unusual for so many earthquakes to happen over several days, said Robert Smith, a professor of geophysics at the University of Utah. "They're certainly not normal," Smith said. "We haven't had earthquakes in this energy or extent in many years." Smith directs the Yellowstone Seismic Network, which operates seismic stations around the park. He said the quakes have ranged in strength from barely detectable to one of magnitude 3.8 that happened Saturday. A magnitude 4 quake is capable of producing moderate damage.

Scientists observe unusual flurry of Yellowstone earthquakes over several days.

 Small Earthquake Swarm on 9 January 2009 near northeast corner of Yellowstone Caldera

A currently modest swarm of earthquakes began in the northeast corner of the Yellowstone Caldera, about 10 miles (16 km) NNE of the north end of the Yellowstone Lake swarm that was active in late December and early January. As of 1930 MST, 10 earthquakes had been located by the University of Utah Seismograph Stations, the largest with M= 3.3 and two other events with M >2.0. Located depths are between 2 and 4 km.

Yellowstone is once again showing a swarm of small earthquakes at this New Moon forward. As of Jan. 1, 2009 you are seeing a swarm of 241 earthquakes...this is cause for concern.

The University of Utah Seismograph Stations reports that a notable swarm of earthquakes has been underway since December 26 beneath Yellowstone Lake in Yellowstone National Park, three to six miles south-southeast of Fishing Bridge, Wyoming. This energetic sequence of events was most intense on December 27, when the largest number of events of magnitude 3 and larger occurred. This December 2008 earthquake sequence is the most intense in this area for some years and is centered on the east side of the Yellowstone caldera. For the Full Press Release Update on Dec. 29th
