I was thinking the other day that you don't hear much about the East Japan Earthquake any more. This makes sense, in that as the immediate danger has subsided and other things happen in the world.
You can even graph the international sentiment ebbing away:
Above is a graph of UK google searches for "Japan earthquake". Below is the same for Japanese searches for "日本 地震":
You can see that, even in Japan, the public eye has wandered onto other issues a surprisingly comparable amount. Us people are great at forgetting about things, but the next time something like this happens, bear in mind that the situation is constantly unfolding, and when you remember it n years from now, it will still be unfolding. Remember that, and how lucky it was you weren't involved.
