Magnitude 1.7 Earthquake Near Tatitlek, Alaska on November 6, 2024

A magnitude 1.7 earthquake struck 45 miles NW of Tatitlek, Alaska, on November 6, 2024, at a depth of 9.9 miles. This event exemplifies the recurring seismic activity in Southcentral Alaska, driven by a complex tectonic framework involving the Pacific and North American plates.

On November 6, 2024, at 02:48:31 AKST, a magnitude 1.7 earthquake occurred approximately 45 miles northwest of Tatitlek, Alaska. This seismic event was recorded at a depth of 9.9 miles (16 km) and the data has not yet been reviewed by a competent seismologist. The epicenter was located at coordinates 61.3214°N latitude and 147.6294°W longitude. Moreover, the earthquake’s proximity to notable Alaskan locations is as follows: it lies 45 miles west of Valdez and 76 miles east of Anchorage among others.

Alaska’s southern region is characterized by its intricate tectonic setting, which is primarily influenced by the convergent boundary between the Pacific and North American tectonic plates. This area is notorious for seismic activity, with mega-thrust faults producing some of the most powerful earthquakes globally, such as the M9.2 Great Alaska Earthquake of 1964. Additionally, intermediate-depth seismicity occurs within the Wadati-Benioff Zone, where the Pacific Plate descends toward the mantle. The region also experiences crustal seismicity from various geological faults, contributing significantly to its earthquake history.

In conclusion, the magnitude 1.7 earthquake near Tatitlek exemplifies the ongoing seismic activity in southcentral Alaska, a region well-known for its complex tectonic interactions. Understanding the causes and implications of such earthquakes is crucial for preparedness and infrastructure resilience. Continued monitoring and research by seismologists remain essential to ensuring public safety against future seismic events.
