Whole villages were destroyed in the April 25 quake in Nepal while large parts of Kathmandu were destroyed, leaving nearly 18,000 people injured and tens of thousands homeless. Nearly 80 people had died in Bengal and Bihar.
Like April's earthquake, today's was shallow - 15 km deep. Shallow quakes are more deadly because the amount of energy released is focused over a smaller area.
