In a significant seismic event, a 7.3 magnitude earthquake struck 54 miles south of Sand Point, Alaska, on Wednesday, prompting the National Weather Service to issue a tsunami warning. The warning affects a broad swath of coastal areas, including South Alaska, the Alaska Peninsula, Kennedy Entrance, and Unimak Pass, as reported by ABC News.
The U.S. Geological Survey confirmed the earthquake’s location and magnitude, highlighting the potential for a tsunami due to the region’s geological characteristics. The Aleutian Islands, where the earthquake occurred, are situated in a subduction zone known for thrust faults that can cause vertical motion of the seafloor, often leading to tsunamis.
This event is part of a pattern of seismic activity in the region. The Alaska Earthquake Center reported 4,257 earthquakes in July 2023 alone, including a notable 7.2 magnitude earthquake on July 15, 2023, which was 69 miles south of Sand Point. These frequent and powerful earthquakes underscore the volatile nature of the area.
Residents in the affected areas have been urged to move to higher ground immediately as a precautionary measure. The tsunami warning remains in effect, with authorities closely monitoring the situation for any further developments. The community is on high alert, with emergency services prepared to respond to any immediate threats posed by the earthquake and potential tsunami.
