John and Doves,
Have a look at this map made by the same guy who created the Christchurch Quake Map.
Use the 'fast fwd' control and see the blistering pace of the quakes!
Odd how Japan allowed nuclear reactors to be built on their soil especially in view of the fact that
their soil is the ONLY place nuclear weapons have been used in anger AND their positioning close
to a major fault line!
Keep looking up,
