John and Doves,
Some have already written about this unusual event.
It is also worth noting that the 9.0 quake in Japan was at 38.322 deg N and the one in Virginia was at 37.936 deg N ie almost the exact same latitude.
Also, on Google Earth the shortest distance (through Alaska) between the two locations is 10,609 kilometres or 103 x 103 kilometres.
Note here that the ONLY divisors are 103. Note also that the 10,609 kilometres is the exact figure I measured the first time. ie I didn't fiddle with it at all.
The day gap is 165 days or 33 x 5 days.
Keep looking up,
