A powerful 7.3 magnitude earthquake struck off Alaska's Aleutian Islands on Wednesday, prompting a tsunami warning and calls for coastal residents to seek higher ground, though officials later confirmed no significant damage or injuries.
The tremor, which hit a seismically active region that has seen several strong quakes in the past five years, including a similar event almost exactly two years ago, initially triggered fears of a large wave. However, the tsunami warning was downgraded after about an hour.
