A significant 7.3 magnitude earthquake struck the coast of Alaska on Wednesday, triggering a tsunami warning across a large portion of the Alaska Peninsula and extending towards Anchorage. The earthquake, centered off Sand Point on Popof Island, prompted the National Oceanic and Atmospheric Administration to issue the warning due to the potential for serious damage. The quake struck near Popof Island with a depth of 20.1 km, making it shallow and potentially more damaging. The National Tsunami Warning Center confirmed the tsunami, affecting the Alaska Peninsula and southernmost mainland Alaska. Notably, the history of seismic activity in Alaska includes the devastating 1964 quake and the most recent 7.2-magnitude tremor in 2023.
