Quebec Ontario quake south of Ottawa

Our local quake zone burped up a 4.0 yesterday south O f Ottawa and felt as far away as Montreal. A 4 is small but our zone has these little quakes all the time, mostly 1s and 2s but a 4 is notable while harmless.
Quakes here are mostly rebound based, meaning that there was once 3 km of ice here and it left, but under that weight the ground was pushed down and now it’s “bouncing” back. Another 5 or 10 thousand years and it will stop.
meanwhile we wait for a 6 to 6.5 to see if the dams and other infrastructure along the river can take it.
