Earthquake Tuesday 12th Jan

Just this evening came the news of the 7.3 mag. earthquake right next to Haiti's capital and 3 million people who live mostly in illegal concrete block shacks with no seismic re-inforcing, even schools and hospitals are collapsing, houses falling in ravines... The phone services are out and there will probably be no word for a few days - we can only wait and hope for the best. Why does it seem Haiti has more bad luck than almost anywhere else on earth? And fewer resources or even time between emergencies to cope with them?
