Mt St Helens Erupting

Hey folks. Just got a call that Mt St Helens is erupting right now, from a roof in North Portland we could see a good bit of ash erupting. As far as I know, it hasnt made it to the local news just yet.
This is a spite to the corporate media. I dont got much, but we got it before them!
any chance you can get some pictures? 08.Mar.2005 18:16

I saw a huge cloud that looked like it could be an eruption. Actually, I think that's the 2nd time within a month that I've seen it while biking home from work. Hrm...

I also remember picking up the oregonian and seeing pictures of the crater. At that point, it looked very similar to a "snackbar" (punani).

There's been steam puffing for months. We've seen it on clear days, repeatedly.

thanks for link 08.Mar.2005 21:21

no pictures but factual overview tells the story and gives possibilities for hazards etc.. thanks!

"Explosive event" at Mt. St. Helens 08.Mar.2005 21:34

The link in the comment above takes you to the US Forest Service webcam showing Mt. St. Helens. The image of the volcano is visible during daylight hours. Mt. St. Helens is closed to the public for a five-mile radius, but the US Geological Survey has the volcano on a Level Two advisory - meaning the volcano is becoming active, but not yet on the verge of a full eruption.

I was watching the show today. For a couple months, a new lava dome has been growing inside the crater as magma forces its way to the surface and hardens. Steam and volcanic gases are venting continuously from the new dome. About an hour before sunset, the steam plume began to grow much larger.

Here's the official report:
--------------------------------------
Mount St. Helens Information Statement,
Tuesday, March 8, 2005, 6:00 P.M. PST

A small explosive event at Mount St. Helens volcano began at approximately 5:25 p.m. PST. Pilot reports indicate that the resulting steam-and-ash plume reached an altitude of about 36,000 feet above sea level within a few minutes and drifted downwind to the east-northeast. The principal event lasted about 30 minutes with intensity gradually declining throughout. The USGS Cascades Volcano Observatory lost radio signals from three monitoring stations in the crater soon after the event started. The cause of the outage won't be known until scientists can visit the crater tomorrow to assess the situation, weather permitting. The event followed a few hours of slightly increased earthquake activity that was noted but not interpreted as precursory activity. There were no other indications of an imminent change in activity.

The current hazard assessment for the ongoing eruption mentions the possibility of such events occurring without warning, and the assessment remains unchanged. The eruption could intensify suddenly or with little warning and produce explosions that cause hazardous conditions within several miles of the crater and farther downwind. Small lahars could suddenly descend the Toutle River if triggered by heavy rain or by interaction of hot rocks with snow and ice. These lahars pose a negligible hazard below the Sediment Retention Structure (SRS) but could pose a hazard along the river channel upstream.

This is an explosive planet! 08.Mar.2005 23:12

Anyone ever hear of the "Giant" at Yellowstone? Let's talk a bit.

I hate to spoil.... 08.Mar.2005 23:20

yoyo

I hate to spoil your "first to report" but as soon as the ash started blowing most local news staions and even a few national had it live.....and according to the time stamp on your message you were about 30 minutes late...
