Outlined circle: this earthquake

In context

How big was it, and why here?

Energy released

175 kilotons of TNT

That is about 12 times the Hiroshima bomb. It released about 367 times the energy of a magnitude 5.0.

Tectonic setting

692 km

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

Depth: deep

580 km

Deep earthquakes (over 300 km) happen deep inside subducting plates. They rarely cause damage, but can be felt faintly over very large distances.
