In context

How big was it, and why here?

Energy released

477 tons of TNT

That is about 1/32 of the Hiroshima bomb. Each whole step in magnitude is about 32 times more energy.

Tectonic setting

195 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

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.

After the main event

Aftershocks within 75 km

USGS lists 3 M2.5+ earthquakes within 75 km in the following 30 days; the largest was M4.5 on August 3, 2001. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
