In context
How big was it, and why here?
Energy released
1 kilotons of TNT
That is about 1/11 of the Hiroshima bomb. It released about 3 times the energy of a magnitude 5.0.
Tectonic setting
27 km
from the nearest mapped plate boundary, between the Banda Sea and Timor plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.
Depth: shallow
33 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.

Aftershocks within 75 km
USGS lists 8 M2.5+ earthquakes within 75 km in the following 30 days; the largest was M5.3 on June 22, 1993. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
