ENV-CRISIS] 9-8-03

I have been not wanting to post about the recent quake increase at Yellowstone until I was sure. Starting last Thursday, I noticed an increase in several things on the seismos around yellowstone.

1) Previously 'quiet' mountains are starting to show small EQs (Earthquakes)
2) 'Flatline' vibrations are increasing
3) Glacier Peak is showing an increase in local EQs
4) Several seismos are 'in sync' with each other regarding readings (usually indicates a deep quake effecting sevaral mountians)
5) Nearby states are showing an increase in EQs
6) The quakes are starting to be 'long and drawn out' instead of your typical 3-5 min shakers.
7) Usually quiet seismos are showing 'micro spikes'.

Now new warnings are coming out.

"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 be 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 (373 miles).

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 .... 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."
