@stevenjgibbons Those are some nice waveforms
@zross Gorgeous! Shame the LASA array isn’t still operational! 512 sites :)
@stevenjgibbons @zross US.MSO is in an old mine tunnel in the mountains outside of Missoula - makes for beautiful regional waveforms! https://ds.iris.edu/gmap/#network=US&station=MSO
@geoginger @stevenjgibbons @zross
... and in this case, waveforms from nearby earthquakes - the epicenter is about 50 km from US.MSO station
