Terrorists acts

This isnt about terrorism, but i think that disaster so big, that happend today naight in Indonesia deserves to be talked about. In 5:54 hours am local time was earthquake with epicentre less than 40 kilometers southern from Yogyakarta, former capital of Indonesia. Until now were in collapsed buildings of city found more than 1400 bodies, airport was damaged, local hospital have critical lack of doctors and nurses. Problem is in fact, taht whole Indonesia is placed over crack in earth, same where is Japan. There are earthquakes every day (most of them really weak) but some times cames big one, and than people die, mostly those poor, who lives in weak houses. This earthquake was marked as 6,2 Richter, so what will happen if there will be really strong? Say about 8 or 9? Probably whole cities destroyed, and milions of dead people-
