Outlined circle: this earthquake

In context

How big was it, and why here?

Energy released

19 kilotons of TNT

That is about the energy of the Hiroshima bomb. It released about 40 times the energy of a magnitude 5.0.

Tectonic setting

503 km

from the nearest mapped plate boundary, between the Eurasian and Indian plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.

Depth: shallow

15 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.
