About this earthquake

A magnitude M5.0 earthquake was recorded near 94 km SSE of Adak, Alaska on July 24, 2026 at 01:03 UTC. With a focal depth of about 10 km, this was a shallow earthquake, whose shaking is usually felt more strongly at the surface. Earthquakes of this magnitude can damage poorly built structures.

The data is provided by USGS and cross-checked across seismological networks.

Why depth matters

Shallow quakes release energy near the surface — shaking is felt more strongly and damage potential is higher.
