Dr. Bruce Cornet's recent analysis of Yellowstone Super-Volcano
Mt. Sheriden has been rumbling (15+ micro-quakes) between 1:00 pm and now (9/7/03). There were three small earthquakes at Yellowstone lake between 10:00 am and 1:00 pm MT (9/7/03), which were felt at Norris Junction. There were some small quakes between Midnight and 6:00 am (9/7/03) at Norris Junction. There was a whole string of micro-quakes (25 or more) at Madison River between 6:00 am and now, which are continuing. There have been sporadic micro-quakes (32+) all day at Mammoth Hot Springs. Micro-quakes started around Noon and have continued to the present at Mirror Lake Plateau. All in all, activity is picking up from a lull for about two weeks, before which a series of small and large quakes (including a 4.4) occurred. That quake prompted the web report.
Steam pressure is apparently building again, and hydrothermal fluids and steam are working their way up through fractures and vents. I do not expect anything unusual or extreme to happen in the immediate future, but if the trend continues, and the number of earthquakes gradually increase with time, more warnings from geologists will ensue.
What you should be alert to is any report that mentions increasing geyser activity, with new fumaroles and steam vents appearing near or on top of the rising dome. The dome has risen about three feet in the past few years, and magma has risen to within 3.7 km of the surface based on quake data. Earthquake loci measured to within 0.5 km under Mt. St. Helens, and people still didn't think it would erupt.
But everything has to be scaled up for Yellowstone, meaning that 3.7 km is not a safe depth. Ground temperatures in the northwestern part of the park are apparently on the rise (up to 200 dg F in some places), killing the vegetation. Large areas of the park are now closed, including areas with geysers, because their water temperature is now scalding and dangerous for visitors.
If more steam vents appear, that means a continuous pathway for pressure release has been established to the magma chamber. If that happens, the pressure in the magma chamber will continue to drop until it reaches a critical stage when the superheated water within the magma explodes. When that happens the super-volcano will blow violently, blowing out a chunk of its cap-rock and sending millions of cubic feet of ash into the atmosphere in a Pompeii-like explosion, but 100,000 times worse.
When you hear those reports, you will have about two days to “get out of Dodge” before the eruption. Unfortunately, as the steam venting subsides, there will be a false sense of security. People will think it was just another cyclical event, and the danger is over. But that will be the farthest from the truth. It will be the quiet before the storm. A major earthquake will suddenly rock their towns for hundreds of kilometers around Yellowstone, and soon thereafter 1,000+ degree pyroclastic flows will descend on them at hundreds of miles per hour, extending out to 600+ km.
That 600 km radius around the caldera will experience total devastation. The next 600 km out may receive as much as 5-10 feet of ash, depending on wind direction. The thickness of ash will decrease away from the super-volcano, but will reach the crop belt in the Midwest (Missouri, Iowa, Kansas, Nebraska, etc.), destroying most of the fertile croplands of the United States. California will be hit hard by falling ash, with its central wine valley severely damaged (the French will love it). Agriculture will have to shift east of the Mississippi for years. The Garden State will once again live up to its name.
In northern Idaho you will have to contend with several feet of ash and isolation. Roads will be closed. Power will be out. Phones will be out. Communication will depend on Ham radios and local stations that have generators. Rescue will take weeks or months. Some areas will never see rescue teams. The survivalists will be best prepared to make it through the difficult months following the eruption. Make new friends. Have plenty of dust masks on hand, because you cannot breath any airborne ash if you want to avoid lung disease. It's what caused mass kills of plains animals 12 million years ago, resulting in extensive bone beds beneath the ash. Drinkable water will sell at the price of gold.
To recap, I don't expect anything to happen in the near future. But with such an unpredictable event, being prepared is your best ticket to survival." (Dr. Bruce Cornet)

: A Monster Awakens?
: by Ian Gurney.
: Published in the UK Daily Express. 10th. September 2003.
: "In the heart of America lies a monster that could
: destroy life on earth."
: Part of America's Yellowstone National Park was closed to
: visitors on July 23rd. this year and remains closed today
: due to high ground temperatures and increased thermal
: activity in the park. National Park Superintendent Suzanne
: Lewis said that "A portion of the Norris Geyser Basin
: on the west side of the park has been closed."*
: On August 7th. the United States Geological Survey (USGS)
: reported that scientists were planning to set up a
: temporary network of seismographs, Global Positioning
: System receivers and thermometers to monitor increasing
: hydrothermal activity in the Norris Geyser Basin and gauge
: the risk of a hydrothermal explosion.**
: On August 10th. the Denver Post reported that Liz Morgan, a
: U.S. Geological Survey research geologist had discovered a
: huge bulge underneath Yellowstone Lake that had risen 100
: feet from the lake floor. The bulge is two thousand feet
: long and has the potential to explode at any time. Morgan
: was quoted as saying that "The inflated plain is a
: potential and serious hazard and possible precursor to a
: large hydrothermal explosion event."***
: Then, on August 24th. The University of Utah Seismograph
: Station reported that a magnitude 4.4 earthquake occurred
: just 9 miles southeast of the southern entrance to
: Yellowstone National Park. USGS scientists agreed that the
: earthquake was "uncommon" in that it was a very
: shallow earthquake, occuring just 0.3 miles below the
: surface.****
: Jacob Lowenstern, a researcher for the U.S. Geological Survey
: and scientist-in-charge of the Yellowstone Volcano
: Observatory said: "Our goal is to understand what's
: driving this volcanic system, and are there indications it
: could be moving into a period of unrest?"*****
: This worrying situation was confirmed on September 8th. by Dr.
: Bruce Cornet, a geologist and paleobotanist with the USGS,
: who explained: "Steam pressure is apparently building
: again in Yellowstone, and hydrothermal fluids and steam are
: working their way up through fractures and vents. If more
: steam vents appear, that means a continuous pathway for
: pressure release has been established to the magma chamber.
: If that happens, the pressure in the magma chamber will
: continue to drop until it reaches a critical stage when the
: superheated water within the magma explodes. Unfortunately,
: as the steam venting subsides, there will be a false sense
: of security. People will think it was just another cyclical
: event, and the danger is over. But that will be the
: farthest from the truth. It will be the quiet before the
: storm."******
: Initially this should be of little or no consequence to anyone
: apart from those planning to visit
: Yellowstone.....................except for one thing.
: Lurking beneath Yellowstone National Park is one of the
: most destructive natural phenomena in the world - a massive
: supervolcano.
: Only a handful exist in the world but when one erupts the
: explosion will be heard around the globe. The sky will
: darken, black acid rain will fall, and the Earth will be
: plunged into the equivalent of a nuclear winter. It could
: push humanity to the brink of extinction.
: Volcanoes have always been a threat to humanity. The Tambora
: eruption in Indonesia in 1815 killed more than 90,000
: people, while the Krakatau eruption in 1883, also in
: Indonesia, killed 36,000. The last supervolcano to erupt
: was Toba in Sumatra 74,000 years ago. It created a global
: catastrophe that dramatically affected life on Earth. Toba
: blasted so much ash and sulphur dioxide into the
: stratosphere that it blocked out the sun, causing the
: Earth's temperature to plummet, and possibly reducing the
: population on Earth to just a few thousand people. For a
: long time scientists have known that volcanic ash can
: affect the global climate. The fine ash and sulphur dioxide
: blasted into the stratosphere reflects solar radiation back
: into space and stops sunlight reaching the planet.
: Temperatures drop dramatically and nothing grows, causing
: mass starvation.
: Bill McGuire, professor of geohazards at the Benfield Greig
: Hazard Research Centre at University College London, says
: that America's Yellowstone Park is one of the largest and
: most dangerous supervolcanoes in the world. "The
: Yellowstone volcano can be likened to a sleeping
: dragon," says Professor McGuire, "whose slow
: breathing brings repeated swelling and sinking of the
: Earth's crust in northern Wyoming and southern
: Montana."
: Professor McGuire went on to explain that: "Many
: supervolcanoes are not typical hill-shaped structures but
: huge, collapsed craters called "calderas" that
: are filled with hot magma and are harder to detect. The
: Yellowstone supervolcano was detected in the Sixties when
: infra-red satellite photographs revealed a magma-filled
: caldera 85km long and 45km wide. It has been on a regular
: eruption cycle of 600,000 years. The last eruption was
: 640,000 years ago, so the next is long overdue."
: Volcanologists have been tracking the movement of magma under
: the park and have calculated that in parts of Yellowstone
: the ground has risen over seventy centimetres, almost two
: and a half feet, since 1923, indicating a massive swelling
: underneath the park.
: "The impact of a Yellowstone eruption is terrifying to
: comprehend." says Professor McGuire. "Magma would
: be flung 50 kilometres into the atmosphere. Within a
: thousand kilometres virtually all life would be killed by
: falling ash, lava flows and the sheer explosive force of
: the eruption. One thousand cubic kilometres of lava would
: pour out of the volcano, enough to coat the whole of the
: USA with a layer 5 inches thick. The explosion would be the
: loudest noise heard by man for 75,000 years."
: The long-term effects would be even more devastating. The
: thousands of cubic kilometres of ash that would shoot into
: the atmosphere would block out light from the sun, making
: global temperatures collapse. This is called a nuclear
: winter. A large percentage of the world's plant life would
: be killed by the ash and the drop in temperature. The
: resulting change in the world's climate would devastate the
: planet, and scientists know that another eruption is due -
: they just don't know when.
: Michael Rampino, a geologist at New York University, quoted in
: a BBC Horizon documentary on Supervolcanoes******* three
: years ago explained: "It's difficult to conceive of an
: eruption this big. It's really not a question of if it'll
: go off, it's a question of when, because sooner or later
: one of these large super eruptions will happen."
: Professor McGuire says "There's nowhere to hide from the
: effects of a supervolcano. One day - perhaps tomorrow,
: perhaps in fifty years, perhaps in 10,000 - it will erupt;
: once again wreaking devastation across the North American
: continent and bringing the bitter cold of Volcanic Winter
: to Planet Earth. Mankind may become extinct."
: So the rumblings currently going on underneath Yellowstone
: should be a warning not just to those who plan to visit the
: National Park, but to the whole world. If the increased
: thermal activity is the precursor to an eruption event, we
: may well be on the brink of the biggest catastrophe the
: modern world has ever witnessed.
