Three 7+ earthquakes in one day? I hope these aren’t a prelude to something bigger.
Greece also had a strong earthquake the other day with several strong after shocks.
Over the years (about 27 or so) I have noticed that the ring of fire has "4 Corners" of activity.
If a 7.X hits in New Zealand then a quake of approximately the same magnitude hits Japan. After that quake, the next 7.X is in South America then the final "corner is in the North American area typically from the bay area to Alaska in range.
Mechanically it makes sense if the Pacific plate is slowly rotating that stresses would build up where the plate boundaries change direction. Then when one "corner" slips it puts stresses on another "corner".
