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.
Looks like alot of steam escaping, or are those clouds (from the web-cam).
diamond those are clouds. I saw some early today that scared me to death, the way they looked early in the morning with all the fog.
Do you live in WA?
The seismographs you've posted do not have the same dates and times for both volcanos. Therefore, it is impossible to confirm your thesis that the activity recorded at Rainer is separate from St. Helens. However, with fair certainity, the activity recorded at Rainer is MOST LIKELY that from St. Helens. You really need to compare the data properly.
It's Rowe's fault: He knows there are mostly liberals who would killed in Seattle, Portland, and north CA when Shasta blows ........
Oops no, I meant that I saw the clouds on the webcam. I'm near Indianapolis, IN.
Some of us have compared. The activity at Longmire, Mt. Rainier, Mt. Hood, seismographs at Rochester high school and Puyallup are all showing the events.
It looks as though it has slowed a bit the last two hours or so.
I took a nap about then. What happened at Mt. Hood around 1:00?
At 11:35 local time there was a quite large event caught.
Another large one at 2:23
Thanks, I guess another gas flight was done today with negative result. No volcanic gas.
Personally, I think the Lord is trying to tell us something...
First, this crazy hurricane season, and now this?!?!
Praying for the west coasters...

Sorry, I'm still in Alabama. But I might get a good bird's-eye view tomorrow.
So my question remains the same. Are these seismographs recording a common event source - St. Helens (most likely) or a separate event / swarm under Rainier (Least likely), which was the general thesis that started this thread.
They are all the same events, emanating from Mt. St. Helens
I am sure a few of the events on the individual sensors are actual small scale background seismicity of the parrticular site.
Your point? I don't recall Mt. Constitution being a volcano, active or otherwise...
