A magnitude 4.9 earthquake struck approximately 55 kilometers east-northeast of Nikolski, Alaska, on Tuesday, November 25, as confirmed by the U.S. Geological Survey (USGS). The quake occurred at 17:16 UTC (8:16 a.m. local time) and originated from a depth of around 68.8 kilometers within the Aleutian region.
Reports indicate that at least four individuals experienced mild shaking, primarily in the western Aleutians, where the Community Internet Intensity Map recorded the tremor’s intensity at IV, classified as light.
The USGS has estimated a 46% probability of aftershocks measuring magnitude 4 or greater occurring in the following week, although the chances of more powerful aftershocks are below 2%. Fortunately, no tsunami warning has been issued, nor have there been reports of injuries or damage to structures as a result of the quake.
Nikolski, recognized as one of Alaska’s oldest continuously inhabited settlements, is located along the Pacific “Ring of Fire,” an area known for its high seismic activity due to the subduction of the Pacific Plate beneath the North American Plate. Residents of the region are encouraged to revisit their earthquake preparedness plans and check that their emergency supplies are sufficient as seismic activity remains prevalent.
This event serves as a reminder of the natural forces at play in this part of the world. Communities in seismically active regions like Nikolski can take comfort in their resilience and the preparedness efforts that enhance safety during such unpredictable occurrences.
