___She does spew, but technically not lava. These Cascade volcanoes do not have the runny flowing lava you see in Hawaii for example, but rather a very thick form which flows like a bulge of clay.

___What spews out is chunks of rock from house size to microscopic. The large pieces, called bombs, flying the least distance from the volcanoe, and the small, called ash, potentially remaining in the atmosphere for years circling the Earth.

___Also spewing out & down the flanks of the volcanoe is a pyroclastic flow which is superheated water, ash, gas, & rock moving many tens of miles per hour. This is what flattened the forest during St. Helens 1980 eruption. This lateral, that is sideways, blast completely took the experts by surprise.

___If the weather holds this weekend, maybe I can get up there with Ace & some camers & get those photos I earlier promised.

There was an interesting brief mention in tonights episode of Conquerors on the History Channel about Mt. St. Helens. Apparently during John C. Fremont's 1844 expedition west his trip took him past a "still smoldering Mt. St.Helens that had erupted the year before." probably the first observation of any kind committed to history of the thing blasting away. Amazing to think we have so little knowledge about its history...

___A lot of news reports these days as we approach the May 18th 1980 eruption anniversary. A KGW news story tonight from scientists who hiked to the East rim reports that the dome is steadily growing in height at a rate of 8 to 10 inches per hour. The emerging dome is moving in fits & starts rather than a smooth motion noted one of the scientists, and I note this jerky motion is reflected in the seismogram traces from instruments at the mountain.

___The volcano cam view has largely remained obscured by fog, clouds, & rain over the last several days, but the occasional clearing rewards a great view. ;)

___Strange as this may seem, I think the mountain's recent activity is responsible for making me feel so awful lately. For over a week now, a 2.0+ at least every day. All the mountain stations registered the big Mointana quake yesterday morning (5.5), & many aftershocks have followed at the Montana epicenter. Any corralation of course is circumspect. We shall see what we shall see.

___The mountain is outputting huge amounts of sulphur dioxide as well as carbon dioxide; it is now the largest polluter in the state! These emmisions follow the local weather patterns which for the most part carries them away from my area to the NE. It is the shaking I feel that I think is making me sick. This is the little known Charlotte King effect & short of moving there is really no alleviating it. Even moving is no guarranty unless it's to an area with no seismicity.

___Just now watching some local news & there is an ash cloud just emmitted from the mountain rising to about 10,00 feet. I checked the volcano-cam & it's not in the view, but the local building camers of the news stations have it in view.

You have to register to see the live view they have up. How many Harry Butts can a registry take? ;)

___2 very distinct active steam plumes today at 2:09 PM PSDT

___As we move into Fall & Winter, I expect a significant change in the seismic signature as precipitation increases. The mountain has substantially more exposed hot rock now & so we have quite a unique volcanic mix of fire & ice coming. :lol: More's the pity we can't see through steam & other clouds. :)

___I took a day pass & visited Mt. St. Helens on Saturday. I took video & my housemate Ace took digital stills. I have put one of Ace's shots in the Science Gallery; it is taken about 30 feet from the camera that feeds the page this thread draws from. The shot is looking East at Spirit Lake.

___I have a photo of the camera coming too for you all, as well as some shots of the mountain (her crown is obscured in clouds), & the Toutle River valley. Enjoy!

PS I tried to convince Ace to let me stand on his shoulders to get in the Volcano Cam picture, but he never came around to it. :evil:
