Hello petewebbgeo,
Thank you for contacting us about this. I would agree with Philip, all the “bumps” that can be seen on the R6C8A seismometer are not earthquakes, but local noise that starts early in the morning and ends around midnight, probably part of the daily cycle of activities of your area.
Furthermore, there has not been an earthquake in the British Isles in the time period you have displayed in the comparison except for this one:
2022/03/31 20:55:59.6 51.939 -2.982 13 M0.5 CLODOCK,HEREFORDSHIRE
But, being an M0.5, it is unlikely that the Shakes have captured it, even if the distance was close.
On the other side, the M7.0, and other stronger far away quakes that have happened in the recent past have been successfully captured by your instrument, as also Philip has shown.
I would also advise using our Android/iPhone ShakeNet App to start navigating this very interesting world of earthquake detection, how to use filtering to eliminate local noise and make distant quakes “pop up” in your data stream, and, consequently, do the same on your PC via SWARM or our DataView service.
If you need further assistance, both the community and I are here.
