In context

How big was it, and why here?

Energy released

951 tons of TNT

That is about 1/16 of the Hiroshima bomb. It released about 2 times the energy of a magnitude 5.0.

Tectonic setting

18 km

from the nearest mapped plate boundary, between the Burma and Indian plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.

Depth: shallow

27 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.

Aftershocks within 75 km

USGS lists 5 M2.5+ earthquakes within 75 km in the following 30 days; the largest was M5.2 on February 21, 2005. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
