A magnitude 1.2 earthquake occurred 28 miles east of Sutton, Alaska on November 25, 2024, with a depth of 11.3 miles. The earthquake highlights ongoing tectonic activity in Southern Alaska, influenced by subduction and crustal processes, necessitating continued monitoring and research in the region.
On November 25, 2024, at 03:08:30 AKST, a magnitude 1.2 earthquake was recorded 28 miles east of Sutton, Alaska, with a depth of 11.3 miles. The event’s coordinates are 61.6524°N latitude and 148.0336°W longitude. This earthquake has yet to be verified by a seismologist. Its proximity to notable locations includes being 36 miles east of Palmer and 69 miles northeast of Anchorage, emphasizing its occurrence in a region historically affected by seismic activity due to tectonic processes in Southern Alaska.
Southern Alaska is characterized by complex tectonic interactions, primarily due to the collision between the Pacific and North American plates. The megathrust fault creates strong earthquakes, including the notable 1964 M9.2 Great Alaska Earthquake. Subduction also leads to intermediate-depth seismicity in the Wadati-Benioff Zone, while crustal seismicity originates from mapped geological structures like the Castle Mountain Fault. Historically significant earthquakes suggest a pattern of activity within the region’s tectonic framework, reflecting an ongoing need for monitoring and research.
In conclusion, the recorded magnitude 1.2 earthquake near Sutton, Alaska, is a reflection of the active geological processes in the region. The tectonic settings, particularly the interaction of the Pacific and North American plates, continue to influence seismic activity across Southern Alaska. Understanding these dynamics is crucial for assessing potential risks and enhancing preparedness in this seismically active area.
