there are two places that really got destroyed by this quake, vii and viii regions... the rest is just random buildings and bridges that collapsed (central zone only)... buildings are build with an antiseismic thing because of the antiseismic regulation we got many many years ago so, not that much destruction, not like haiti, and think that this quake was even stronger, 8.8 in chile, 7.1 in haiti. the problem was that they are a reaaaally poor country so they can't build antiseismic buildings. and we got a tsunami, that's why those 2 regions collapsed with this event (lots of old buildings fell down plus a few new ones here and there).
