Mt. St. Helens Magma Reaches Surface
daquake writes "Volcanic rock has flowed to the surface of Mount St. Helens' crater, creating a new lava dome after weeks of seismic activity, the bulge had risen at least 330 feet since scientists noticed it September 30. Geologists said there is still a chance of explosive ash eruptions from the 8,364-foot mountain, and the immediate area around the volcano remained closed."

Anyone know if they keep an archive of the pics from this thing? (No links I've found on their site to one) I swear I saw an orange glow around 9pmEST the night this was first reported here, since I still had it loaded in a tab and checked it occasionally. Unfortunately I simply kept checking it without saving any of the pics, and was quite suprised to see the next day there was no report of magma flow or fire, just mentioned the small steam eruption which I was watching from approx 8:30pmEST onwards. The cam IIRC is 5 miles away, so I couldn't really tell if the glow was fire or magma, now I'm thinking it perhaps was reflected magma light from deeper within, hence no mention of flow outside the volcano as it appeared then.

note: the complete loop is approximately 2.5 hours long and you can see that the glow is definitely real across several images

I actually watched it erupt from about 35 miles away in Rainier, OR. It really really creepy watching a cloud of ash rise into the sky and then disappear... And then we heard a rumbling sound, which is when they said on the news that magma has reached the surface. I thought it was pretty cool. =) At least it's not as bad as the 1980 eruption where everyone had to buy a stockload of air filters for their car... It was a huge mess...
Also, I climbed MSH the day before they shut down the mountain. There were a couple dozen earthquakes while I was on it, including one right when we were at the top. Of course I didn't know it at the time, only when I got home and checked the website. If you're close by, I highly recommend going, even if it doesn't blow while you're there. Supposedly (!!!) it's safe, plus you can see the lava dome and its new little buddy from the visitors center.
You'll have your very own mirror of images. Of course, you'll also have an intensive task running every 5 minutes which takes a fair amount of disk space...
It seems you forget that Seattle has the option of evacuating to the north towards Vancouver, Canada. Yes. It is too in the path of a volcano, Mt. Baker which is slightly east of Bellingham, WA, but Mt. Baker has been rather quiet for the past number of years and even if it were to blow its top, Vancouver and the area around it would be relatively okay.
You missed the bulge that is building in the The Three Sisters in Central Oregon.

Cut and paste from the above article..
confirming geologists' belief that a large bulge that has grown over the past seven years near the dormant volcanoes could be caused by an upwelling of molten rock miles underground.
The truth shall set you free!
The bigger concern is Tacoma - it's pretty much going to be flattened if the volcano goes and the glacier melt ends up following the valleys as expected. One possible escape method is by large ship. Tacoma does have a harbor sufficient to support ocean-going cargo frieghters You could fit an awful lot of people on one ocean cargo ship, especially if all you are planning on doing is moving them a ways north up puget sound and don't plan on actually heading out to the ocean.
(One of the reasons Ranier is such a danger isn't so much the size of the eruption itself that would likely occur, but the pretty magestic white slopes. In an eruption all those icy glaciers will liquify and make a massive rushing flood of muddy goo all the way to Puget Sound, ruining all cities in the way. Ranier has the most ice of any mountain in the United States.)
Don't label something "offtopic" unless you know the topic well enough to tell what's on topic.
It is formed after all from many small eruptions, such as this one, that deposit lava onto the sides of the volcano and thereby causing it to grow larger. IANAG (I Am Not A Geologist).
What's the big deal other than its interesting to watch it unfold infront of your eyes, and it probably will keep on doing this for some time to come so now isn't your last chance to see this happen. Granted with all the new technology available to us it can provide us with some valuable insight into the inner workings of the earth, but it seems the geologist know exactly whats going on here.
Other than these few scientific points of interest, there really is not much point in sucking up this story from every single media outlet. Its business as usual for the volcano and time we worried about more important things (at least those we can influence).
And no I don't live on the other side of the world. I'm from just a wee bit North of the border.

It's not a very good novel (in fact, it's downright ludicrous, as it's one of those where all the world's terrorists seem to be working together as one unified group, a concept which Parker and Stone are ridiculing in 'Team America') and it's insanely right-wing, ultra-militaristic and reactionary, as such books are wont to be, but Robinson might now get some extra sales just because he was lucky with the timing.
You must think in Russian.
One of the coolest things to happen with the volcano cam recently is that night has gotten slightly more interesting. For the first couple weeks, all you could see at night was a dark noisy image. In the last couple days, a faint glow from the magma in the dome has been visisble.

considering the event is still in progress, there's plenty of time to still be worried in. Last time, it built up the same way, the big "Kaboom" as you call it, occured after the side of the dome gave way, releasing the pressure quickly, allowing the magma to explosively release it's dissolved gases.

I've been monitoring the volcanocams this morning and noticed one spot near the top of the dome, that has been "glowing" pretty consistantly. Take a look at:

Keep an eye on the one steam plume on the upper right of the crater. As the sun goes down on the camera (roughly 22:00 Oct 12), you can see a prominant reddish spot that remains all the way through, well, the time I write this.
Just because you can mod me down, doesn't mean you're right. Shoes for industry!
