Mt. Ranier and others heating up. OH OH

IS THE ENTIRE NORTHWEST HEATING UP?

I'm not a seismologist by any means, but looking at the various "short period" seismometers found at this link, one can see that the activity in the Northwest is clearly increasing and seemingly now continual at Mt. St. Helens specifically. I added the snip of information below from the site to help explain the type of seismographs that are used in taking these readings. They also mention that reading these seismographs is like reading a book. Each line from left to right is like one sentence and then the next line, left to right, becomes the next sentence. Hope this helps the other amateurs out there. You will notice that all these seismographs that I linked to are specifically short period, which are designed to take readings locally, picking up weak activity in the region they are specifically located. Mt. Rainier, Mt. Hood and Rattlesnake Mt. are all pretty active and looking like Mt. St. Helens did prior to her increased activity. Sorry so long. Just trying to be more informative.

SEISMOMETER TYPES

The PNSN operates a heterogenious mix of seismometer types for monitoring a variety of types of earthquake activity. The operations of seismographs are funded by different agencies and serve a variety of purposes.

Short Period - Identified in Webicorders with the suffix "EHZ" - sensitive velocity seismometers with a response peaked around 1 Hz. Typically only a single vertical component. Primarily used for determination of location and magnitude of regional earthquakes.

Broadband - Identified in Webicorders by suffixes: "BHZ" or "HHZ" (Vertical), "BHE" or "HHE" (East-West horizontal), or "BHN" or "HHN" (North-South horizontal - velocity seismometers with a wide frequency response. Typically has a vertical component and two horizontal components. Primary purpose is to record waveforms from regional and distant earthquakes for research purposes.

Strong Motion Identified in Webicorders by suffixes: "ENZ" (Vertical), "ENE"(East-West horizontal), or "ENN" (North-South horizontal) - accelerometers with three components. Designed to record on-scale waveforms from moderate and large regional earthquakes

Shes got a wild wild life. Had to put that, you put oh oh. LOL... if anybody ever heard that song, they know.

If Mount rainer goes it could make Mt.St.Helens seem like a firecracker in comparison.

If that happens you might ask these questions...

And you may ask yourself
How do I work this?
And you may ask yourself
Where is that large automobile?
And you may tell yourself
This is not my beautiful house!
And you may tell yourself
This is not my beautiful wife!

Same as it ever was

Prior to the '80 eruption there was increased seismic activity in the other mountains of the cascade range also. They're all very near each other, when one raises hell, they all wake up a little...it's normal.

I guess volcanology has it's people I disagree with also...
