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 &#8220;decimated&#8221; 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.<\/p>\n<p>http:\/\/service.iris.edu\/irisws\/timeseries\/1\/query?net=DU&#038;sta=TPSO&#038;cha=HHZ&#038;start=2021-01-01T00:00:00&#038;end=2021-01-07T00:00:00&#038;scale=AUTO&#038;deci=0.01&#038;format=plot&#038;loc=00<\/p>\n<p>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.<\/p>\n<p>Videos are helpful, but they need full documentation and links to help teach and to encourage global collaborative research on the Internet.<\/p>\n<p>Thanks for sharing!<\/p>\n<p>Richard Collins, Director, The Internet Foundation<\/p>\n","protected":false},"excerpt":{"rendered":"<p>https:\/\/www.youtube.com\/watch?v=ZayEvWsNu6I Seismology Research Centre My Comments: I searched for &#8220;Peters Seismological Observatory&#8221; and found it is listed as DU.TPSO (network.station) in IRIS.edu.
