In context

How big was it, and why here?

Energy released

15 kilotons of TNT

That is about the energy of the Hiroshima bomb. It released about 32 times the energy of a magnitude 5.0.

Tectonic setting

137 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

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.

After the main event

Aftershocks within 100 km

USGS lists 31 M2.5+ earthquakes within 100 km in the following 30 days; the largest was M6.3 on January 21, 1995. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
