Thankfully, it seems that the energy released by the quake did dissipate over distance, and even the closest islands to Japan were relatively unaffected.
Japan though looks like it has taken a real beating and most of my friends are in Okinawa which was predicted to get hit, but I haven't heard anything yet either way? My friend's place was right by the Pacific so I am praying they headed inland or even to the safety of one of the U.S bases.
