Hi Lowell. If the quakes near Parkfield were occurring about 60km or more south of Parkfield I would be a little concerned. However these quakes are occurring in an area known for its creep.

However a moderate quake can’t be ruled out. These quakes are near the area of the 1966 quake. That was 36 years ago. Could be enough time for a sufficient amount of strain to have built up for another quake near the same magnitude. Take Care…Don in creepy town
