Pixies CD ~ Mount St. Helen- I

This is starting to be WAY more use than I had wanted for our members locations maps. :( Once a year for a SMALL, unusual event would have been more than enough to have to let our members know we had people in the area that could be effected.

SEATTLE (AP) - Government seismologists raised the alert level for Mount St. Helens on Saturday after its second steam eruption in two days, saying the next blast could threaten life and property in the remote area near the volcano.
The hundreds of visitors at the Johnston Ridge Observatory just five miles from Mount St. Helens were asked to leave. They went quickly to their cars and drove from the scene.

I’ve only heard that seismological signals associated with magma movement has been noted. Volcanic activity is NOT as accessible, refined or predictable as atmospheric conditions. I will try to post “authoritative” information as I am able to gather it.

I know there are other Pixies in Washington State, but here are the members that have given permission to post their location.

For those interested, here is a site with a bit of information.

As of this posting, this is the most current "official" update.

(keep in mind that media ratings are the way their prices are set for advertisers. Volcanism is a science with sensational events and a lot of uncertainty. Sift your information based on the source ;) )

Here is the latest published word on the rock & roll events in Washington State and our latest Pixie map.

Mount St. Helens Update, October 2, 2004, 7:00 P.M.
Current status is Volcano Alert (Alert Level 3); aviation color code RED
At 2 pm today, we increased the alert level to Volcano Alert due to a change in the character of seismic signals (50-minute-long tremor) that occurred immediately after the small steam emission at 12:15. Since the tremor stopped, seismic character has changed back to the type of earthquakes we have detected since the beginning of the volcanic unrest. Earthquakes are occurring at a rate of 1-2 per minute with maximum earthquake magnitues of about M3. All earthquake locations remain shallow.
Today field crews took additional thermal images of the dome and crater. Deformation crews were in the field retrieving data from GPS instruments. Results are not yet available from today's late gas flight.
Currently wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), combined with eruption models, show winds this evening will be from the east and southeast and any ash clouds will drift to the west and northwest.
We continue to monitor the situation very closely and will issue additional updates as warranted.
Press conferences will be held tomorrow at the Supervisor's Office of the Gifford Pinchot National Forest. The morning press conference is at 9:30 am.

I assume the times are GMT -8

And here’s hoping that the black star on this map doesn’t move to a new location and none of our people will be calling the home, their digs……….literally. :cheers:

Thanks so much for doing this Pantyfanatic!!!!!!!!!!!!

Thanx for the heads up PF!

PF, as always, you're terrific :x:

I'll second that. PF, ya' done good. :)

PF...

You are marvelousssss...

ty

I agree.... you're amazing, PF. Thank you for taking upon yourself the job of keeping us informed, I feel safer just having you around. Truly.

I have been following this with interest having been through the last eruption 20 years ago. Still have a little jar full of ash that had blown all the way to Portland, Oregon where I lived at the time.

My thoughts and prayers are for everyone involved and especially our Pixie family. Let's hope she doesn't cause to much damage this time.

PF you are a blessing. :)

Great work as always PF, although the members living in Washington aren't the only ones affected by this. I was passing through Portland on friday on my way to Corvallis (my new home) when it vented. Being big into Geology I've been watching this with great intrest.

With natural disasters in both of our states I think it is only rational for Aqua and I to take refuge somewhere mid nation :D

You're welcome to stay in my bed, ...I mean, house until Aqua gets here Lil. :rolleyes:

In spite of my “journalistic talents”, I’m happy to report the events that I already have interest in am following. I’m doing this with what I call my “instinctual proximity theory”. :confused:
I long ago noticed that there seems to be a very natural reaction and effect difference within us, based more on how close we are to an event than even it’s severity or danger to us personally. We can sit at breakfast and read of genocide taking place in a far off country, that involves hundreds or even thousands of people and shake our heads or shrug as if we were reading a novel or a chapter from a history book. Yet if a neighbor knocks on the door to inform us of the fatal auto accident victim from across the street, our physiological rate changes and it’s a topic of concern for the next few days. It’s the psychological bond we feel to a person that seems to be the difference. With the “family feelings” we often sight among our members, I of course have a concern when any natural event occurs that could affect one of us. So you see, it’s only a task for me to create something readable to post. ;)
Here is the major change from the last official report.

Mount St. Helens Update, October 3, 2004, 7:40 P.M.
Current status is Volcano Alert (Alert Level 3); aviation color code RED
At 2 pm yesterday, we increased the alert level to Volcano Alert due to a change in the character of seismic signals (50 minute long tremor) that occurred immediately after a steam emission at 12:16 P.M., recognition of ongoing uplift of the crater floor, and reports of sulfur gas odor. In addition, we believe that there is a significantly increased probability that gas-rich magma is moving toward the surface. After another period of tremor starting at 2:57 A.M. this morning, seismicity returned to discrete earthquakes. Seismic activity decreased gradually until about 2:00 P.M. then increased again, reaching levels comparable to those prior to steam and ash eruptions. M3 earthquakes are occurring at a rate of about one every 5 minutes. All earthquake locations remain shallow.
Yesterday’s gas sensing flights detected significant concentrations of carbon dioxide north and west of the dome. No significant levels of sulfur gasses were detected. Hydrogen sulfide odors detected by helicopter crews are attributed to steam emissions. These low levels of hydrogen sulfide are likely the result of boiling of the hydrothermal system.
Results from GPS measurements indicate no significant deformation of the outer flanks of the volcano. However, visual observations and photographic analysis show large-scale uplift (10’s of meters) of part of the glacier and a nearby segment of the south flank of the lava dome. This suggests rise of magma to shallow levels. Additional steam and ash eruptions could occur at any time. There is also an increased probability of larger magnitude and more ash-rich eruptions.
Today field crews took additional thermal images of the dome and crater and conducted gas sensing, infrared and geologic observation flights. Deformation crews retrieved data from GPS instruments and lowered a new GPS station from a helicopter onto the dome. In addition, two telemetered microphones are now operating to detect explosions. …..

As I've said before......nothing like this happens in England, so if you two need a refuge, we have a spare room......unfortunately, there's only one bed in it, but somehow I think you're gonna manage! ;)
