Japan has more than 1500 earthquakes a year. Japan is located in a region called the ring of fire. Now its not a name for show. This region has alot of volcanic acitvaty and is very seismically active. If you look at the location of japan and understand it all one kinda understands that something like this was bound to happen. And since japan is a country with millions of people the damage would the as we have seen it. This is not the first time something like this has happend and it wont be the last.
So if you ask me, no i do not belive in such things. As daddyairplanes pointed out. We are all so connected today. The world has gotten so much smaller. And knowing about all these catastrophes all the time makes it look like its the end of time but the fact is the amount of earthquakes and hurricanes and all that has not changed per year. Its still the same it just happens to be that they hit highly populated areas.
The wonders of chaos one might say, well not wonders in this case but yeah. Its all in the probabilities.
