ANCHORAGE, Alaska—An ongoing eruption of a remote volcano in Alaska’s Aleutian Islands produced an ash cloud so large Tuesday that warnings were sent to pilots about potentially dangerous conditions.
An ash cloud with an initial height of around 5.5 miles (8.9 kilometers) was reported following the morning eruption of Shishaldin Volcano. But by early afternoon, ash emissions were below 1.9 miles (3 kilometers), and the aviation alert was downgraded, according to the Alaska Volcano Observatory.
