In context

How big was it, and why here?

Energy released

181 kilotons of TNT

That is about 12 times the Hiroshima bomb. It released about 380 times the energy of a magnitude 5.0.

Tectonic setting

89 km

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

Depth: intermediate

179 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.
