In context
How big was it, and why here?
Energy released
7 kilotons of TNT
That is about 1/2 of the Hiroshima bomb. It released about 14 times the energy of a magnitude 5.0.
Tectonic setting
248 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: intermediate
124 km
Intermediate-depth earthquakes usually break inside a plate that is sinking into the mantle. Shaking spreads over a wide area but is gentler at the epicenter than a shallow quake of the same size.
