USGS raises eruption alert on Mount St. Helens
University of Washington, Pacific Northwest Seismograph Network ^ | sep 29 2004 | usgs

Posted on 09/29/2004 7:56:16 PM PDT by paladinkc

Increased seismicity overnight prompted raising the alert level to Volcano Advisory (Alert Level 2) at 10:40 A.M., PDT, this morning.

Throughout the day the seismic energy level has remained at an elevated with a rate of 3-4 events per minute including an increase in the number of events between Magnitude 2 and 3. All earthquake locations are still shallow and in or below the lava dome. In addition, initial data from the GPS instrument on the lava dome that was repaired Monday morning suggest that the site moved a few inches northward Monday and Tuesday, but has since been stable. Such movement is not surprising in light of the high seismicity levels. A USGS field crew continued their deployment of GPS equipment today in order to monitor any ground movement on the lava dome, crater floor, or lower slopes of the volcano. Another gas flight this morning produced a result of no significant volcanic gas detected, as was the case on Monday. Two press conferences were held at CVO to update the media. Tomorrow’s field work includes continued GPS deployments.

The current hazard outlook is unchanged from that outlined in this morning’s Volcano Advisory. Updated wind forecasts from the National Oceanographic and Atmospheric Administration coupled with an eruption model indicate that the wind direction will shift from northwesterly to northeasterly tonight. Therefore any ash clouds produced tonight will drift southwestward.

Confusion at this morning’s press briefing at CVO regarding Alert Levels resulted in numerous calls to emergency management agencies from the public about which is the correct level. We are at Alert Level Two—Volcano Advisory.

no no no

Bush lied, there were no WMD.

Mt. St. Helens is erupting because of Global warming and because rich people don't pay enough taxes.

(did I leave anything out? Hlliburton? Bush didn't win the popular vote?)

Here's a live webcam of MSH. It's dark now, but if anybody sees a glow, pay attention!
I use GeekTool to keep this picture on my desktop. So I can see it erupt (or not). http://www.fs.fed.us/gpnf/volcanocams/msh/images/mshvolcanocam.jpg

I live 60 miles north of St. Helens. I know it's hoping against hope, but I hope that a huge flaming lava bomb flies north and takes out Evergreen College.

Good grief! Yes, the Evergreenies are a bunch of long-haired leftist freaks. But it is such a beautiful campus. Where I teach looks like a big parking lot by comparison (a commuter school in the midwest). <laughing>

Thanks, I probably wouldn't have watched the webcam tonight but the idea about a glow is great. I got a BIG scare today when I pulled it up on my computer and saw the low clouds and fog. I thought for a minute that it was erupting then.

Turn the dang spotlights on!

Seriously, I checked the webcam this morning about 2 am and you could barely make out the outline of the mountain. But we had a beautiful, brilliant full moon last night, I probably could have sat on my front porch and read by it.

I regularly watch the seismograms for all the mts here. St.H has been showing, for at least two months prior, a continuous low level harmonic that rarely subsided at all.

She's gonna go this time.

Another seismograph station has been openned on the mountain and is now online. Go to http://www.pnsn.org/WEBICORDER/GREEN/welcome.html
and scroll down to June Lake. It is less jumbled than Dome Station, but is still extremely active. The 1980 events went on for 2 months prior to the big one on May 18. Could this be the beginning of another series of eruptions of just another dome building event.

Seconded.

Meanwhile, I'm checking my emergency supplies in case falling ash has us home bound in Seattle for a few days.

Paranoid? Maybe. But we were checking our volcano supplies in the office today as well (yes, we get volcano and earthquake emergency kits at our UW offices and our emergency preparedness handout has what to do in case of volcano eruption - first thing, cover the computers; gotta protect that IT investment.)

I'm an east coast girl and this is freaking me out completely out, I must say.

No you're not paranoid, you'd be crazy not to get yourself and family ready for this! Just out of curiosity, has anything been said about closing Seatac airport or Portland when it hits.

I doubt if they will need to close Sea-Tac. But the news tonight said the FAA has pre-approved route changes for Portland and Sea-Tac if need be.

Ummm...no.

She "went" the last time.

This time will be some steam / ash / rocks a couple thousand feet up - tops.

Minor stuff - as far as "stack blowing" goes.

Do you think it will happen in, say, 48 hours.

Can anyone please clarify, I have heard that the volcano alert was raised from 1 to 2 out of 3 levels. Other media (who else) are saying it was raised from 2 to 3 out of 4 levels.

Hard to say. Don't know if there is pressure building, but one has to assume there is. This mountain has gone with explosive eruptions before, as well as another mountain nearby, Crater Lake.

Much of the rock in the cascades is almost diamond hard slate, old ocean floor that has metamorphosed and been raised up by subduction.

It can sustain tremendously high pressure.. but when it gives, it gives with a bang.

I do not suspect this phase will simply end without some sort of release of the pressure and uprisings that are happening.

So expect something within 36-72 hours. If nothing happens, it MIGHT slow down, but I doubt it. Some of the volcanos here have had eruptive phases that go on for 50 to 100 years.

Take a look at the webcam. Is that a light somebody turned on or what at the bottom left of the screen. It looks to be too low and left to be the volcano, but not sure. At 22:34 local on the webcam.

King 5 says we are at level two.

Level four is volcano dormant.
Level three is volcano unrest.
Level two is volcano advisory(where we are now).
Level one is eruption.

King 5 also reporting an increase in number and intensity of the quakes, including an unstated number over magnitude 3.

If it goes within 24-36 hours, Portland will get it.

Mt Rainier seismographs are recording quakes from St Helens.

George Noury had a guest on the first hour, who gave Mt. St. Helens a 56% chance of blowing in the next two days.

Can't think of a more deserving target than The Evergreen State College--what a pretentious name! We do need more ranges.

No doubt if it blows, the Dems will claim that Karl Rove caused it to draw attention away from the debate.

I didn't live here the last time St. Helens erupted, but I moved out the year after, and when I got up in the morning there was always a thin coat of ash on my car.

This time, they don't expect it to be nearly as bad - and it's quite a ways away, actually. Obviously it may matter a great deal to those that live in the immediate area, but I'm not expecting much, and I don't really feel a need to prepare.

If I'm wrong though, I'll ride it out and post an ashy picture of my Audi TT for you. : )

What I remember most about the effects of the volcano around here: truly BEAUTIFUL sunsets, from all the ash in the upper atmosphere.

Too much of a price to pay, however. I hope your predictions are true.

Yep. Seismicity: The world-wide or local distribution of earthquakes in space and time; a general term for the number of earthquakes in a unit of time.
