In context

How big was it, and why here?

Energy released

85 kg of TNT

That is about 1/177,558 of the Hiroshima bomb. A magnitude 5.0 releases about 5,623 times more energy.

Tectonic setting

79 km

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

Depth: shallow

22 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 17 M2.5+ earthquakes within 50 km in the following 30 days; the largest was M3.5 on June 18, 2026. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
