In context
How big was it, and why here?
Energy released
5 tons of TNT
That is about 1/2,814 of the Hiroshima bomb. A magnitude 5.0 releases about 89 times more energy.
Tectonic setting
139 km
from the nearest mapped plate boundary, between the Indian and Burma plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.
Depth: shallow
33 km
Shallow earthquakes (under 70 km) produce the strongest surface shaking for their size, so they are the ones most likely to cause damage near the epicenter.
