Earthquakes rock my world!

For comparison purposes I also attached a couple of seismograms of recent Giantess eruptions: The July 6 eruption starts at 6:13 MST.  The large signal at 6:02 MST is from a distant 6.1 earthquake. The October 14 eruption starts at 3:48 MST.  There are a handful of local earthquakes, like the one at 6:02 MST.  I would guess that the long duration signals at midday and late afternoon are weather-related noise. If Giantess erupts during a rainstorm, I don't think we'd ever be able to tell from the seismic record.
