A powerful 7.3 magnitude earthquake struck near Sand Point, Alaska, early Thursday morning, prompting widespread tsunami warnings across coastal regions of southern Alaska, including Anchorage, Homer, and parts of the Aleutian Islands.

🌊 Tsunami Warning Issued

Shortly after the earthquake, the National Tsunami Warning Center activated a tsunami warning for portions of coastal Alaska. Sirens were sounded in multiple towns, including Homer, Kodiak, and Sandpoint, advising residents to move inland or to elevated areas.

While initial tsunami waves were relatively minor — with sea-level changes of up to 0.3 meters recorded in some locations — experts warned that aftershocks or secondary waves could follow.

“Although the first wave wasn’t destructive, further tsunami activity remains possible. Residents in low-lying areas should stay alert,” said a spokesperson from the Alaska Tsunami Warning Center.
