In context
How big was it, and why here?
Energy released
239 kilotons of TNT
That is about 16 times the Hiroshima bomb. It released about 501 times the energy of a magnitude 5.0.
Tectonic setting
214 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: shallow
38 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 6 M2.5+ earthquakes within 100 km in the following 30 days; the largest was M5.3 on November 17, 2000. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
