Outlined circle: this earthquake
In context
How big was it, and why here?
Energy released
64 kilotons of TNT
That is about 4 times the Hiroshima bomb. It released about 135 times the energy of a magnitude 5.0.
Tectonic setting
186 km
from the nearest mapped plate boundary, between the Okhotsk and Pacific plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.
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.
