In fact, tourism has not been affected at all after the Tsumani: people think it's still time to help in the recovery of these places. I was amazed when, watching the news, I could see how tourists hepled in the construction of hew buildings, as well as temporal schools, etc.
However, it's not the same as before. Rather than a touristic trip, they do it to help people. It will take at least some months or even a couple of years to find these places as a touristic zone.
