In context
How big was it, and why here?
Energy released
175 kilotons of TNT
That is about 12 times the Hiroshima bomb. It released about 367 times the energy of a magnitude 5.0.
Tectonic setting
515 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
598 km
Deep earthquakes (over 300 km) happen deep inside subducting plates. They rarely cause damage, but can be felt faintly over very large distances.

After the main event
Aftershocks within 100 km
USGS lists 1 M2.5+ earthquake within 100 km in the following 30 days; the largest was M5.6 on March 24, 1967. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
