In context

How big was it, and why here?

Energy released

9 kilotons of TNT

That is about 1/2 of the Hiroshima bomb. It released about 18 times the energy of a magnitude 5.0.

Tectonic setting

64 km

from the nearest mapped plate boundary, between the Nazca and North Andes 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.
