In context
How big was it, and why here?
Energy released
548 kilotons of TNT
That is about 36 times the Hiroshima bomb. It released about 1,148 times the energy of a magnitude 5.0.
Tectonic setting
7 km
from the nearest mapped plate boundary, between the Rivera and Cocos 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.
