Two quakes together, right at the tip of the advancing shear wing. Maybe they don't know the pumping has stopped. Although the sudden stopping of earthquakes was the most dramatic thing I've ever seen, there is a chance the whole thing has been opened up (fracked) so that natural forces can take over. Or maybe they've been sneaking in at night!
I know that I will be stunned, if the extent of their pumping is ever 'leaked' to Ontario Leaks, since they must have exceeded every previous earthquake-creating effort.
If there is a natural feed, I would expect a sudden drop with the stoppage of pumping, and a slow buildup.
