We know this was a tiny earthquake, but that is activated the soil basins of Boston, with 20-30 second rumbling. As well, it was felt at Seabrook.
They are now going through a phoney inspection that will not find anything. Far better would have been instrument readings with a PGV. They probably got hit with 5 mm/s. If the old me still existed, I would have railed at the lack of seismic recording at nuclear plants, but nobody cares.
Darlington has good instrumentation, and would have recorded this size of nearby earthquake, but it would be like pulling teeth to get the results. :)
Update: this was felt as far as Ontario. So really, if you felt this earthquake in Ontario, get earthquake insurance!
