In context

How big was it, and why here?

Energy released

951 kg of TNT

That is about 1/15,825 of the Hiroshima bomb. A magnitude 5.0 releases about 501 times more energy.

Tectonic setting

129 km

from the nearest mapped plate boundary, between the North American and Pacific plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.

Depth: shallow

69 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 50 km

USGS lists 3 M2.5+ earthquakes within 50 km in the following 30 days; the largest was M2.8 on May 12, 2026. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
