Mount St. Helens may erupt soon!

What's the big deal? Volcanoes go off every once in awhile. It'll make a lot of smoke and fire and ash will be a pain in the ass. The casualties it's going to cause in a certain area will likely be comparitive to a bad night of drunken driving and regular motor accidents. Casualties from the first eruption had a lot to do with scientists who wanted to pet the volcano and residents who simply wouldn't leave no matter what.

Have to check out the experimental spectrograms from Helens. Incredible. The dome is taking magma...no doubt about...

www.geophys.washington.edu...

This set of graphs records the frequency of movement. The higher the frequency, the stronger the movement. Look at any other station to see the baseline.

If you look at the Helens series starting 9/26 and track through today...you see a massive increase in movement across all frequencies. Not good.

Much easier to read.

Geez man. That "regular" motor accident could be the death of a child playing in the street. Must you use statistics in this context?

Well... actually there's silhouette showing "under noise" if you look accurately.

Yes, I suddenly realized it was night there... However it doesn�t look all that good in daylight now either. It�s supposed to look like this (but I guess it could be just foggy weather now) :

Mount St. Helens Volcano Advisory (Alert Level Two)
September 29, 2004 10:40 A.M., PDT
U.S. Geological Survey Cascades Volcano Observatory, Vancouver, Washington
University of Washington Dept. of Earth and Space Sciences, Seattle, Washington

Over night, seismic activity at Mount St. Helens has accelerated significantly, which increases our level of concern that current unrest could culminate in an eruption. We are increasing the alert level to the second of three levels, which is similar to Color Code Orange of the alert system used by the Alaska Volcano Observatory and analogous to the National Weather Service's hazard watch. Earthquakes are occurring at about four per minute. The largest events are approaching Magnitude 2.5 and they are becoming more frequent. All are still at shallow levels in and below the lava dome that grew in the crater between 1980 and 1986. This suggests that the ongoing intense earthquake activity has weakened the dome, increasing the likelihood of explosions or perhaps the extrusion of lava from the dome. The cause and outcome of the accelerating unrest is uncertain. Explosions from the lava dome could occur suddenly and without further warning. During such explosions the dome and crater floor are at greatest risk from ballistic projectiles, but the rim of the crater and flanks of the volcano could also be at risk. Explosions would also be expected to produce ash clouds that rise several thousand feet above the crater rim and drift downwind. During today, wind forecasts from the National Weather Service, combined with eruption models, show that ash clouds will move in a southeasterly direction and could dust areas tens of miles or more from the volcano with ash. Landslides and debris flows from the crater that are large enough to reach the Pumice Plain are also possible. If the current unrest is being driven by a small slug of magma at shallow depth, extrusion of lava could also occur.

At present there is no evidence that new gas-rich magma has ascended to shallow levels and could generate a large sustained eruption. But we are being especially vigilant to become aware of such evidence should it appear.

We continue to monitor the situation closely and will issue additional updates as warranted, whether activity escalates or returns to background levels.

I live near Mt St Helens, I haven't received any local warnings but my daughter's field trip ther has been cancelled, My animals have been acting very strange as you can imagine, they seem to feel something is wrong lately.

I used to live in seattle . Lots of talk about Mt rainier. What are the odds of St helens going off and setting Rainier off? Probably a slim chance but just say it did and in turn set off mount baker.

I can't call it but it seems the entire ring of fire is starting to awaken. Volcanoes in russia, Alaska, Washington, Hawaii all showing signs of activity, earthquakes in Cali. Is mother earth getting irriated?

If so what would this do to yellowstone? Could there be a catastrophic event in the enar future. I don't know but it makes for very interesting reading.

I dont know if Earth is mad or if this activity is part of Earth's natural cycle. But I can tell you im a little spooked Would the Sacramento area be in any potential threat from any of the Caliquakes?

And don�t forget the hurricanes.
It�s mother earth telling the americans:
"Sign the Kyoto agreement, sign the Kyoto agreement!"
Let�s hope it�s not too late...

Hehe where is Mt. Rainier located again?

How many times this has to be said: Hawaiian eruptions are continuous, it's normal for them to pour lava many years continuously.
They're caused by different reason than volcanoes in ring of fire.

And big eruptions like Long Valley, Toba or Yellowstone happens very rearly, but they balance that with volume of eruption:





Instead of "new Yellowstone" I would expect eruption like Mount Mazama had 7600 years ago...
If name doesn't ring the bell it's currently known as Crater Lake.

Mount St. Helens Update
October 1, 2004 8:00 A.M., PDT


The alert remains at a Volcano Advisory. The seismic energy level remains elevated with a rate of 3-4 events per minute and earthquakes as large as magnitude 3.3. All earthquake locations are still shallow and in or below the lava dome. Data from a single GPS instrument on the east side of the lava dome suggest that total movement is ont the order of 7 cm (

Earthquakes. They�re mostly over Mag. 3 now...

Get updates here

The local paper is giving us a 70% chance of a "minor to moderate" event sometime in the next week or so. St. Helens doesn't worry me nearly as much as Rainier though. They are also saying that if it happens within a week the prevailing winds will carry the ash south/southwest and into the Portland area.

If ash does fall on the eastern side of the state again I'll try to get some pictures, but all the predictions I've heard say that it won't be near the scale of the 1980 eruption, so I doubt that would happen. I guess we'll know soon enough.

We talked about this in school today. Alot more information here. Hurricanes, earthquakes, and volcanoes, what's next?

There is now smoke coming from the volcano.
Scientists are now saying that there are dome building eruptions going on.

She has starte to erupt.

It just started erupting. Watching it on cnn now.
