A tsunami advisory has been issued after a magnitude 7.2 earthquake struck off the coast of Alaska late Saturday, officials said.
The earthquake hit offshore about 55 miles southwest from Sand Point, Alaska, at a depth of 13 miles (about 20.9km) on Saturday night (2:48 a.m. ET), according to the US Tsunami Warning Center.
The quake prompted a brief tsunami warning for parts of Alaska near the Aleutian islands, extending from Unimak Pass to Kennedy Entrance, before being revised to a tsunami advisory. There is no tsunami threat for other Pacific coasts in the US and Canada, the advisory said.
The Alaska Volcano Observatory provided a threat notice for the Shishaldin volcano after it sent up a plume of ash earlier Saturday, according to a social media post.
There is a “watch” currently in effect for the Shishaldin volcano. According to the observatory, seismic tremor aptitudes began to increase at around 5 p.m. local.
