Outlined circle: this earthquake

In context

How big was it, and why here?

Energy released

58 kilotons of TNT

That is about 4 times the Hiroshima bomb. It released about 122 times the energy of a magnitude 5.0.

Tectonic setting

6 km

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

Depth: shallow

35 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.
