The timestamps and latitude indicate a shift north of the quake activity. It started out in the lake and is moving north toward the shoreline.

A bunch of data has indeed disappeared. I imported the earlier data from that site into Excel so that I could make plots of depths of the earthquakes. In the earlier data there were a large number of quakes between 2 and 3 km deep. There were clusters of quakes at those depths followed by quakes between 2 km and the surface. Kind of scary.

Perhaps what is going on is that automated equipment is interpreting individual quakes out of very noisy seismometer data. Maybe quakes disappeared from the link because vulcanologists have reviewed the data and decided a number of those machine interpreted quakes were just noise and not actual quakes.
