On August 5, 2026 at 08:55 UTC, a magnitude 3.4 shallow crustal earthquake struck 36 km W of Denali National Park, Alaska, at a depth of 10.4 km and coordinates 63.5530°, -152.4500°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.5 (light).

Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 3.4 earthquake near Denali National Park, Alaska?

The magnitude 3.4 earthquake that struck 36 km W of Denali National Park, Alaska on August 5, 2026 at 08:55 UTC had a depth of 10.4 km. It was felt by 1 person with maximum shaking intensity of MMI 3.5 (light). For context, this was a minor earthquake typically detected only by instruments.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.4 earthquakes can continue for several days and gradually diminish over time.

Understanding This Data

Magnitude 3.4 earthquakes are typically only recorded by instruments.
