In context

How big was it, and why here?

Energy released

16 kilotons of TNT

That is about the energy of the Hiroshima bomb. It released about 34 times the energy of a magnitude 5.0.

Tectonic setting

59 km

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

Depth: shallow

10 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.
