I searched for “Peters Seismological Observatory” and found it is listed as DU.TPSO (network.station) in IRIS.edu.
The profile for DU.TPSO is at http://ds.iris.edu/mda/DU/TPSO/ where the instruments are explained.
Unfortunately, only the STS-2 is listed and only the HHE, HHN and HHZ 100 samples per second three axis seismic data is online there. But it has been archived since 2015 and is current.
There is an event listed with the EarthScope system at http://ears.iris.washington.edu/Data/Summary/gauss_2.5/DU/TPSO/station.html for TPSP, but it is not very well explained and mostly without context.
It is possible to see what the data looks like by using the timeseries service at IRIS.edu. Here is an example of one week of the HHZ (vertical channel from the STS-2 (listed as location 00 at the facility) for the first week of 2021. It is a good quiet site. Not sure what the spikes might be. I “decimated” to 0.01 samples per second. The STS-2 has a 120 second period. The vertical axis is meters per second. YouTube has primitive sharing, so I cannot include the plot.
The Time Series Builder is at http://service.iris.edu/irisws/timeseries/docs/1/builder/ just fill in DU TPSO 00 HHZ and a date range (here I used 2021-01-01T00:00:00 to 2021-01-07T00:00:00), Correction (apply total sensitivity) and then click on the link at the bottom to run it.
Videos are helpful, but they need full documentation and links to help teach and to encourage global collaborative research on the Internet.
Thanks for sharing!
