In context
How big was it, and why here?
Energy released
14 kilotons of TNT
That is about the energy of the Hiroshima bomb. It released about 30 times the energy of a magnitude 5.0.
Tectonic setting
539 km
from the nearest mapped plate boundary, between the Sunda and Australian plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.
Depth: deep
480 km
Deep earthquakes (over 300 km) happen deep inside subducting plates. They rarely cause damage, but can be felt faintly over very large distances.
