While checking the seismographs tonight for the region, it is becoming apparent that Mt. Rainier is also awakening along with Mt St Helens. At first, I had hoped that the seismographs at Mt Rainier were merely picking up the earth movement from St Helens, but the tremors do not correlate.
By checking the charts for St Helens back on the 25th of the month - when the current event began - the buildup is easily seen. There are occasional quakes that are of noticeable strength, while the others are extremely small. Moving forward from the 25th, you can see the intensity grow, as well as the frequency shorten. Well, the same scenario is playing itself out right now under Mt Rainier, especially the Longmire station.
Posted below are the charts showing this growth at St Helens, along with the more current ones from Mt Rainier. If Mt Rainier's activity increases in a manner similar to Mt St Helens, this will be an interesting time indeed for all of this region......
Here is Mt St Helens from the 25th:
And here is St Helens again, from the morning of the 26th:
This is Mt St Helens right now. Constant earth movement......
Alert status for Mt St Helens is now at "3". Now for Mt Rainier. Here's the chart for Rainier from yesterday morning/afternoon:
And this is the current chart for Mt Rainier:
As you can see, the earth is starting to move under this volcano as well. The duration of the quakes under Mt Rainier is longer, and the frequency is longer than at Mt St Helens, but there is obviously something going on here as well. I really want this one to go back to sleep.
Yes, but did you stay in a Holiday Inn Express last night???
Sorry, I couldn't resist. Seriously, though, I saw a report on Mt. Ranier several years back. The fact that it's overdue for an eruption, and the high population surrounding it. Rather alarming.
No..but I did sleep in a Holiday Inn last night!!
Put that in your pipe and smoke it.
Lighten up, newbie!

'Listen, I don't wanna talk out of turn but i think you should put the town on alert, there's a hell of a lot of activity up there.' "Harry, I know it was intense up there but i don't want to cause a panic over a few minor tectonic tectonic quakes" 'Minor?' "The biggest one we measured was 2.9..." 'I don't give a damn if it was a 1.1, those quakes were shallow, Paul, damn shallow, I was up there, i felt them.' "Harry, you don't".. 'They were not tectonic they were magmatic, this thing is gonna blow!' "Harry, I'm warning you, I'm not gonna have you scaring the hell outta everybody because of guesswork and hunches! Another 48 hours will tell the tale, you get a grip".
If I stumble onto it, I'll try and find this thread and let you know.
May I ask you a question because frankly, I don't know squat about volcanoes?
For the exeption of ones in the sea, are land based volcanoes typically located in a moutain? Can they be underneath the flatlands?
And, is it possible to have more volanoes than those that we are aware of?
. . . . uhhhh, especially
the one deep off the Oregon coast?!
Actually, I have long noted such things. A main reason I'm on the USGS email list.
I guess that joke doesn't translate well outside the duck-and-cover generation.

MOUNT ST. HELENS, Wash. - The flurry of earthquakes at Mount St. Helens intensified further Thursday, and scientists warn that a small or moderate blast could spew ash and rock as far as three miles from the crater in the next few days.
The lahare from Mt. Rainer would basically wipe out Seatle.
Stratovolcanoes don't "ooze" - they go "BOOM!"
Yup! Like I said on another thread, the rock here ain't your wimpy shales and limestones and sediments.
It's hardened slate and basalts and granite.
When it pops, it pops good.
The volcano cam just went down.
Volcanoes form in areas of high tectonic activity. If you live in Kansas, I wouldn't worry about one popping up in the field behind your house. One COULD form in California, though.
Well, everybody likes a good boom, but I was under the impression from the USGS that if the 1980 blast was a 10, this event would be a 1; and further, that it would be like the secondary eruption at St. Helens in the late eighties, more of a hissing, oozing event.
Finally, being overeducated in the humanities, I don't know what 'stratovolcanoes' are, though I could hazard a guess based on my understanding of dead languages. ;O)
Yup.
I can see Rainier from the windows at work. I am new to all this and reeeally don't want to see either one of them act up. However, we were getting our emergency volcano eruption supplies (they give them to us at work) in place yesterday.
Now that I think about it, is it too weird to start carrying my own home emergency face mask in my back pack in case I have to walk home in falling ash?
The problem is, I got a $500 bill for any volcanologist who, before 1980, said the Explosive potential on St. Helens even existed.
They keep telling us volcanos maybe might possibly could have a potential to erupt and do a little bit of damage.
Then we here about them getting shiskabobbed on some hill in Mexico.
The camera is on again with clear skies except for some low fog.
