Outlined circle: this earthquake
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 15 times the energy of a magnitude 5.0.
Tectonic setting
9 km
from the nearest mapped plate boundary, between the Molucca Sea and Birds Head plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.
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.
