As far as I know 1 grade = 31 times stronger. In Haiti the magnitude was 7.1, in Chile is 8.8 so this means 8.8/7.11*31=38 times stronger. In Haiti was a dissaster. I couldn't imagine what could happen here in Bulgaria after 8.8 earthquake.The earthquake is about 300-400 times stronger. The magnitude scale is logarithmic so the difference between the 2 earthquakes is 10 exp(1.5(8.8-7.1))=350
It is good that the earthquake was short - only 10-30 seconds. I saw some pictures where the damages are less than these in Turkey several years ago. I hope that there won't be many victims.
