In context

How big was it, and why here?

Energy released

11 kilotons of TNT

That is about the energy of the Hiroshima bomb. It released about 22 times the energy of a magnitude 5.0.

Tectonic setting

128 km

from the nearest mapped plate boundary, between the Birds Head and Banda Sea plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.

Depth: shallow

15 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 75 km

USGS lists 1 M2.5+ earthquake within 75 km in the following 30 days; the largest was M5.9 on November 2, 1926. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
