Rainier Earthquakes

Two appearing on USGS Earthquakes:

Magnitude 2.0 - MOUNT RAINIER AREA, WASHINGTON
Depth 0km
earthquake.usgs.gov...

Magnitude 1.5 - MOUNT RAINIER AREA, WASHINGTON
Depth 2.6km
earthquake.usgs.gov...

other than that there isn't much activity.

Not much really happening, but a lot of this:




Notice that these tremors don't go below their line much, so what is doing this?

11.4km to the west:

Magnitude 1.0 - WASHINGTON
depth 11.7km

Although there is a little activity on Longmire at the moment, the rest of the webicorders are quiet at the moment.

Yesterday on the Mt. Fremont webicorder there was a long tremor (about 3 minutes) starting at 19:20 UTC (11:20 local).

Today it's mainly flat so far, however the Camp Shurman Webicorder is showing rather large trmors, but they are not visible on the other readouts.

An earthquake which shows up on the USGS quake hazards site:

Magnitude 1.4 - WASHINGTON
Depth 5.7km

This quake was on the eastern side again.

46.855°N, 121.604°W

Haen't had much chance recently to post, but here is an updatwe:

this is the most interesting recent seismic activity.

currently Mount Fremont is showing a bit of interesting activity, but the two closest to the summit are quiet with just small tremors.

Fremont seems to have had quite a bit of activity, but whether it is bad or not I don't know.

I just found this, from this morning's Webicorders:

I think this probably shows a Harmonic tremor, but confirmation would be good. The bit after the main quake I think is the Harmonic tremor.

Sorry if the image is too big, but I think otherwise the detail would be lost.

I think the first signal may be the Kuril islands quake, but if that were so I would have expected it to be the same size on all the webicorders. I just wonder what the continuing signal is.
