SPECIAL REPORT: NEW SEISMIC STATIONS FOR GLACIER PEAK
In September of 1998, two new seismograph stations (SLF, Sugar Loaf; and WRW, Wenatchee Ridge) were installed near Glacier Peak to better monitor seismicity. These stations are located south of Lake Chelan. Station WRW is close enough to appear on the map of seismicity.
In September of 2001, a new seismograph station, GPW, was installed on Glacier Peak volcano. Dr. Jeff Johnson, a former UW graduate student, helped with installation, and took photographs of the installation procedure and station location. Visitors can find his installation page here:

Wow. Those analysis are amazing. That you are able to determine so accurately that this was an ice quake with just the one station is SOOOO cool. I’m looking at the current signal (11/4/11 @ 11:50 am Pacific time) and it really doesnt look like wind. Weather here is cold and sunny…certainly can be windy up there…but the signal seems to steady for that??

I see the one you are talking about but I have not got the data file yet. I will listen to it tomorrow and let you know.

That sounds so…..odd. It definitely builds and builds…..then ‘pop’. Wierd. My gut tells me that it is something….I dunno. Not normal? Thanks for the sounds bites, love to listen to them!
