In context

How big was it, and why here?

Energy released

158 kilotons of TNT

That is about 10 times the Hiroshima bomb. It released about 331 times the energy of a magnitude 5.0.

Tectonic setting

145 km

from the nearest mapped plate boundary, between the North Andes and South American plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.

Depth: shallow

25 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.
