A significant earthquake registering at a magnitude of 7.3 occurred off the coast of Alaska’s islands, prompting a tsunami. The U.S. Geological Survey reported that the earthquake took place at 12:37 p.m. local time, approximately 54 miles from Sand Point, Alaska, at a depth of 12 miles beneath the Pacific Ocean.
Following the earthquake, the National Weather Service’s National Tsunami Warning Center confirmed a tsunami and noted that while impacts were expected, they do not anticipate widespread flooding from this event. Initially issued as a Tsunami Warning, it was later adjusted to a Tsunami Advisory indicating that the effects could pose dangers primarily to individuals situated very close to the water.
Cities that received tsunami warnings include Sand Point, Cold Bay, and Kodiak, with the first waves projected to arrive in Sand Point at 1:30 p.m. local time. Subsequent waves are expected in Cold Bay at 2:25 p.m. and Kodiak at 2:40 p.m.
Tsunamis are characterized by a series of waves driven by significant geological shifts, such as earthquakes or landslides, where the initial wave may not necessarily be the largest. This event underscores the ongoing seismic activity in the region and the importance of preparedness in coastal communities.
As this is a developing situation, updates are forthcoming. Residents and officials in affected areas are advised to stay informed of alerts and take necessary precautions.
