About this earthquake

On November 27, 2025 at 17:11 UTC, a magnitude M6.0 earthquake occurred near 12 km WNW of Susitna, Alaska (United States). With a focal depth of about 69 km, this was a shallow earthquake, whose shaking is usually felt more strongly at the surface. Events of this size are considered strong and can be dangerous in inhabited regions.

The data is provided by USGS and cross-checked across seismological networks. United States: over the past 24 hours, QuakeMap24 logged 187 earthquakes, the strongest at M4.0.

Regional average: 15.2 km
Why depth matters

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