In context
How big was it, and why here?
Energy released
85 kilotons of TNT
That is about 6 times the Hiroshima bomb. It released about 178 times the energy of a magnitude 5.0.
Tectonic setting
84 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
18 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.

After the main event
Aftershocks within 100 km
USGS lists 7 M2.5+ earthquakes within 100 km in the following 30 days; the largest was M4.8 on July 30, 1980. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
