In context

How big was it, and why here?

Energy released

951 tons of TNT

That is about 1/16 of the Hiroshima bomb. It released about 2 times the energy of a magnitude 5.0.

Tectonic setting

58 km

from the nearest mapped plate boundary, between the Sunda and Australian plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.

Depth: shallow

10 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.
