In a wider warning for Alaska and British Columbia issued earlier, the Anchorage Office of Emergency Management said: "If you are located in this coastal area, move inland to higher ground. Elsewhere in the United States, Washington state, Oregon, California and Hawaii were under tsunami watches, which eventually were lifted. Larry LeDoux, superintendent of the Kodiak Island Borough School District, says schools were open as shelters and estimated there were about 500 people at the high school. The quake - among the strongest in US history - hit at a depth of 10km (6.2 miles) some 175 miles southeast of Kodiak Island at 00.31am local time (9.31am in the UK) on Tuesday, with waves of up to 32ft (10m) reported. Parts of Alaska and the west coast of Canada were issued with a tsunami warning, while a tsunami watch was put in place for the entire US west coast - with "hazardous waves" said to be possible within the first three hours of the earthquake. Kodiak was projected to get the first tsunami wave, and officials warned residents to evacuate if they lived in low-lying areas.

People reported on social media that the quake was felt hundreds of miles away, in Anchorage.
A 7.9 magnitude earthquake occurs in the Gulf of Alaska. A tsunami warning is issued for coastal Alaska and British Columbia, and the entire U.S. West Coast is placed under a tsunami watch. Areas of Alaska remain under a tsunami advisory. It is tied as the sixth-largest earthquake ever recorded in the United States, but there are no reports of significant damage or fatalities.
