A 1.7 magnitude earthquake would be imperceptible to a human. And it definitely wouldnt cause power outages. It takes a 4.0 before you can feel it. A 4.0 is thousands of times stronger than a 1.7.
This is the answer quora gives:
No. Seismographs can record such quakes because they’re very sensitive, but human beings are rather less so. A quake really has to be in the 4 range before a human being will notice anything out of the ordinary, such as their desk shaking.
So Im thinking this is either straight comms or something man made was happening in DUMBs and tunnels.
