Outlined circle: this earthquake
In context
How big was it, and why here?
Energy released
17 kilotons of TNT
That is about the energy of the Hiroshima bomb. It released about 36 times the energy of a magnitude 5.0.
Tectonic setting
182 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
35 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.
