Four earthquakes registering at 6.1, 6.0, 5.2, & 5.0 in Canada’s NW Territory were removed from ANF or Array Network Facility between the hours of 19:39 & 19:46 on Saturday April 14th. Why they were moved I do not know, but they were large enough to be recorded by the ANF.
I do have screen shots (posted by others) of the events as they occurred.
