Sorry if that sounded dumb, i am new at trying to understand the webicorders.

It is my understanding that when the webicorder looks like that it means that magma is moving which is understandable with how much the dome is growing at MSH. But there have been lots and lots of micro-quakes around 2.5 or so for the past few days so maybe some of that is from those also.

I am by no means an expert I am learning everyday so I might be mistaken.

You know, I really have to wonder what is going to happen. Rainer did this same thing before the big earthquake on Dec. 26th. As well as before the 8 pointers after. It lasted about a month if I remember correctly.

maybe we should take more notice of when rainer is "active", because it shows that something is gonna happen.

Dec 26th & now the Pakistan quake

Yea, about Rainier........RUN!!!

That quake calmed it down for a day or two, but now it is worse than before. I am thinking that the pressure builds up and escapes at the weakest point. Rainier has been showing us when pressure is building, but the weakest point has been elsewhere. With it comming back this dramaticly, I have to wonder if it has, now, become the weakest point.

Where are you folks getting this information about Rainer? I haven't seen anything on the news, and a Yahoo! news search didn't show anything either...

Yep, TA. It's been cycling through that type activity for what seems like 2 weeks or so now. It's quite disturbing.

so wassa deal? These charts gotta like go off the scale or something, all blacked and redded out before it's real serious?

I don't know. All I can tell you is that the USGS has never stated anything but "continues at normal background levels", no matter how jicky the charts look, it's always at normal background levels.

So I guess it doesn't mean much. **

sorry.

So this is pretty much a panic/freak/sky is falling sort of thing, huh?

I don't know what this type of activity on the webicorders means. I can tell you when I see something that appears to be magmatic encrochment. But if this is just rock cracking from magma flow...that's some big cracks! And the periodicity that is occurring with it is kind of weird too.

Simple answer - I don't know!...it just scares me!

I see that there were some 2.9 earthquakes at MSH around the same time as that webicorder reading (at least I think it was around that time-I'm not great at time changes) That is about the only thing I can see that is obvious. But I don't see anything for that specific area -- don't know why there isn't a listing on the earthquake page for it when it shows for MSH.

I was concerned with Rainier, so I sent an email to the Southwest volcano research center, asking what they thought. I got an email back about 4 hours later from R.B. I thought I would post it so you all can read. His answer is first my email is last.

Hi Jennifer !

Thank you for your e-mail and question regarding Mt. Rainier.

First, most of us in the volcano business consider Mt. Rainier to be the single most dangerous volcano in the United States today. The recent earthquake activity is common place with Mt. Rainier, i.e., coming and going in sort of cycles as it did last year and again this year. Of course the Cascades Volcano Observatory (CVO) and certainly we here at SWVRC pay close attention to the seismic activity of this volcano. Currently, Eruption Pro 10.6 has forecasted Mt. Rainier with a 12.94% probability of eruption for year 2005 with current data loaded. Of course this probability calculation can increase (or decrease) with additional data on seismic, deformation, thermal, etc.

Again, many thanks for you e-mail and question. And I guarantee you we will be watching this mountain closely !

Respectfully,

SOUTHWEST VOLCANO RESEARCH CENTRE

Hello, I was wondering what you think of Mt. Rainier right now. There are quite a few of us watching the seismographs via the usgs website. We have noticed that since last year, Mt. Rainier has acted up before all of the 7+ quakes. He acted up again before this last quake, quiet down, and now he is acting up again. Several of us are curious/concerned. When Mt. St. Helens started up last year, they explained that what looked like a heart beat on the seismographs was magma. Rainier has developed that "heart beat". So, what do you think Rainier is doing?

Thanks for your time,
Jennifer

It does not sound like they are taking it lightly either. One thing I found interesting, not sure if it is worth mentioning, but he sent a copy of what you read to over 50 other people. I recognised some of the names as volconologists. I am not sure why he would have sent this to so many people. Anyway, Rainier is a scary topic. Especially with the pattern lately.
