Outlined circle: this earthquake
In context
How big was it, and why here?
Energy released
548 kilotons of TNT
That is about 36 times the Hiroshima bomb. It released about 1,148 times the energy of a magnitude 5.0.
Tectonic setting
530 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
662 km
Deep earthquakes (over 300 km) happen deep inside subducting plates. They rarely cause damage, but can be felt faintly over very large distances.
