The U.S. Geological Survey (USGS) registered an earthquake with magnitude 6.5 that occurred on September 17, 2026 at 14:19:52 UTC. The epicenter was located 177 km west of the settlement of Nikolski on the Aleutian Islands, Alaska, at coordinates 52.956° N and 171.503° W. The depth of the epicenter was approximately 98 km. According to the PAGER impact assessment system, the alert level was determined as "green," indicating a minimal risk of significant destruction and casualties. The maximum estimated intensity according to ShakeMap was V on the scale, while according to the "Did You Feel It?" survey based on eight reports, the recorded intensity reached III—the earthquake was felt but caused no serious damage. The Tsunami Warning Center issued an appropriate notification due to the submarine nature of the epicenter; however, no significant threat to coastal areas was detected. The Aleutian Islands region is characterized by high seismic activity due to its location on the boundary between the Pacific and North American tectonic plates, where earthquakes of various magnitudes occur regularly.
