In Kodiak, Alaska, the blare of sirens pierced the night air, warning residents of a potential tsunami. Faced with the warning, people hurriedly sought shelter, and the tense moments were captured on social media videos.

Magnitude and location details

According to the United States Geological Survey (USGS), the quake struck at 10:48 p.m. Saturday about 106 kilometers south of Sand Point, Alaska. The earthquake, which initially measured 7.4 on the Richter scale, was later reduced to 7.2.

Tsunami advisory and subsequent cancellation

The US National Weather Service issued a tsunami warning saying the quake struck at a depth of 13 miles (21 km). However, within an hour of the initial warning, the advisory was canceled, allaying fears of a tsunami impact.

Affected Areas and Hawaii’s Safety

The National Weather Service in Anchorage, Alaska, issued a tsunami advisory for coastal Alaska from Chignik Bay to Unimac Pass. Notably, Kodiak Island and the Kenai Peninsula are considered safe from significant impact. The Hawaii Emergency Management Agency immediately confirmed that there was no threat to the Hawaiian Islands.

Aftershocks and precautionary measures
