Heres a link to the seismogram trace from a station on the South flank of the mountain. The main event begins at 5:36 (a black trace line) & lasts about 12 minutes . The phto I took was at 6:13. They are saying the burst reached at least 30,000 feet.

Click on the 3-letter designations above the trace to see other stations. They lost communications with 3 devices inside the crater during the eruption. :Alien:

Turtle: CBS ran a pretty cool time-lapse of the erruption yesterday. Did you see it? Unfortunately its not on their web site, and the USGS VolcanoCam site doesn't have any video of the latest erruption ether....

___Before Europeans settled my area, many native tribes populated the region. Their legends record previous eruptions of Mt. St. Helens, which natives called Loowit among other names.

____This first link is a report on some of those legends & the tribes who told them:

___This second link is the home page of the preceding link; I just found it today so I don't know it well, but it looks like an excellent volcanoe reference.

If you check the St. Helens cam just now, she is mantled in snow & steaming a plume from her new dome. How completely the new snow is covering her & how completely it imbues a false sense of serenity. Beautiful! :)

+++The camera is socked in with rain & clouds, but I just checked one of the seismic stations & the last few hours show a harmonic tremor signal:

+++This may be a wind signature, as the other stations do not record the same signal. We have however had three significant quakes of 3.0 under the mountain in the last 18 hours.

+++The mountain is also receiving considerable rain & snow the last day & a half & this considerable volume of water in the crater is at the least creating consdierable steam. :)

ASTER is featuring a recent infrared view of Mt. St. Helens. It's an interesting shot.

___That's a great view C1ay; I talked Ace into setting it as the backdrop.

___This even's local news reported that in the last 48 hours, over 8" of rain has fallen on Mt. St. Helens & that flooding is now possible down the Toutle River system which drains the crater. Under the current weather conditions, no one is making any direct observations.

___I expect a big steam/ash burst any time in the next day or two; all that water going into the vents & just past the Worm Moon. More to come. :)

___All is largely quiet on the mountain today. She is covered in snow & shrouded in cloud, patiently chuffing up the occasional steam plume & pushing her new dome skyward.

___Of course no officials want to say so, but there is every possibility that St. Helens will bury most of Vancouver & Portland the same as Vesuvius did Pompeii. If she does, maybe they'll find me in a thousand years, cast in stone with a beer bottle to my lips and then put me on display in a glass case. :)

___Absolutely. All Cascade volcanoes belong to the same system, ie. a subduction zone, & they all have explosive potential. St. Helens has the same potential to explode as Mt. Mazama did 7,000 years ago leaving behind Crater Lake.

___Further on the idea of ending up like Pompeii here, some of these eruptions don't merely explode, but rather persist for hours or days spewing tons of ash & gas into the high atmosphere. Were it but for a different wind when the last burst in March went to 36,000 feet, we here in Vancouver (USA) would have received an ash fall of over 1 cm.

___I live amost perfectctly equidisdant from Hood, Adams, & St. Helens; talk about your ring of fire!
