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

125 km

from the nearest mapped plate boundary, between the New Hebrides and Australian plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.

Depth: intermediate

154 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.
