Emergency management officials in British Columbia say there is no threat of a tsunami after a magnitude 4.6 earthquake struck Monday near Alaska.

The province’s EmergencyInfoBC website said the earthquake was recorded at 12:39 p.m. local time (1:39 p.m. PT) and occurred 161 kilometres southwest of Kodiak City, Alaska.

A statement from the U.S. National Tsunami Warning Center said a preliminary assessment determined there was no tsunami danger to the region as a result of the earthquake.

The U.S. Geological Survey said the earthquake struck at a depth of 58 kilometres and a handful of people in and around Kodiak City reported feeling the shaking.

The Alaska Earthquake Center says the Aleutian megathrust subduction zone is the source of the most power seismic activity in the region, including a magnitude 7.8 earthquake in 2020 and a magnitude 8.2 earthquake in 2021.

Seismic activity in the Aleutian megathrust zone is primarily caused by the Pacific Plate sliding beneath the North American Plate, according to the centre.
