On October 6, 2026 at 18:34 Coordinated Universal Time, a magnitude 5.5 earthquake struck Alaska. The epicenter was located approximately 92 km to the north-northwest of the settlement of Aleneva, at a depth of 87.6 km. The coordinates of the focus are 58.802° north latitude and 153.609° west longitude. According to the U.S. Geological Survey (USGS), the PAGER impact assessment system assigned the event a green alert level, indicating a minimal probability of significant damage and casualties. The ShakeMap intensity map recorded a maximum intensity of IV on the Mercalli scale, corresponding to moderate shaking. However, based on the results of the "Did You Feel It?" eyewitness survey, the maximum registered intensity reached level V — approximately 300 people reported strong shaking, indicating more notable effects in certain areas compared to the calculated data. The considerable depth of the focus (over 87 km) contributed to a reduction in the earthquake's destructive force at the surface, despite the relatively high magnitude. Such seismic events are common in the Alaska region, which is located in a zone of high tectonic activity at the boundary of the Pacific and North American plates. No reports of casualties or material damage have been received at this time.
