Just wondering what this is -- a fluke?  It's not Helens, as this
activity corresponds with nothing there. (You can see the Helens
background seismo during the "quiet times", and it's much weaker.)

After a rather quiet period for the last several hours,  I've noticed a
change in the pattern of activity of the seismographs.
Previously the South Ridge should the largest signals and most activity and
the signal was usually saturated.   At about 15:17PDT the South Ridge signal

My oh my has the S/N ratio gone to hell around here lately.

USGS published a satellite photo of Mt. St. Helens taken on September 28th:

I'm just curious. What is that huge light grey feature north of the volcano?

Fox News Channel cut to another eruption event at ~ 0905 PT. Appears to be
another predominantly steam event. Interesting this event occurred ~ 12
hours after Mon event.

I haven't seen mentioned anywhere if Parkfied broke the
surface. I presume it did, but just want to confirm.
Also, anywhere online to get pictures yet?
TIA

They have stolen secret Russian earthquake machines and will use them

All the seismographs are goin nuts and it's smokin.

Hey Susan, did you draw the short straw today? :)

By setting up a seismic array around the volcano at an acceptable distance
from the volcano, specified waves from EQ's near the volcano can be used to
map the magma body. By doing this on a ~ continuous basis the rising magma
can be mapped to a reasonable accuracy. For an example of ...

I wonder if it can't get that Nora Jones song out of it's head.

So she finally burped.
Was it really any surprise with the way the earthquakes got shallower and
shallower and as frequent as 4 quakes per minute???
The science was there documenting the whole process.

Today is the 17th anniversary of the Oct 1, 1987 Whittier
Narrows Quake. The quake struck at 7:42 am local time with
a magnitude of 5.9.
