Brian and I had a meeting with seismologist at the National Earthquake Information Center in Colorado. They pointed us to a very cool tool called MUSTANG that shows statistics for every seismic station that is fed into the IRIS Data Management Center (DMC).

The tool can be found here:https://services.iris.edu/mustang/

It can be queried by changing the URL at the top, they have a few examples. One interesting rabbit hole we went into was looking at spectrograms for the LHO vault seismometer, known to the IRIS DMC as UW.LIGO. Here are the spectrogram results for the three components:

You can see the seasonality of the microseism and also another periodic low frequency signal of unknown origin. There are tons of interesting things to look at, like the ground motion models:

Just putting it out here in case anyone wants to check it out and go down the same rabbit hole Brian and I did.
