In context
How big was it, and why here?
Energy released
32 kilotons of TNT
That is about 2 times the Hiroshima bomb. It released about 68 times the energy of a magnitude 5.0.
Tectonic setting
44 km
from the nearest mapped plate boundary, between the Eurasian and Indian plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.
Depth: shallow
25 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.
