Double Wave Whammy

Who can forget the massive Tsunami that invaded Japan in March last year, following a magnitude 9 earthquake off their coast.

It has now been established, thanks to unrelated research conducted by NASA and Ohio State University, that the massive wave was a result of two Tsunami's that merged, forming a super tsunami that did not lose it's power while being able to travel long distances.
By some twist of good luck from the researcher's side, satellites were in the right place at the right time and detected the two fronts merging far out at sea.

Scientists labelled this as a 'in in a million' chance of capturing this type of data and it shed's more light on the super waves that are formed after earthquakes (and out of space body collisions for that matter). Scientists think that this will help them understand the mechanics of these destructive waves and may go a long way to assisting forecasts in the future.

This is the first evidence scientist have of the merging of super waves, although it has been in theory form for a while now.
