Volcano eruption sparks aviation alert
A volcano has erupted again in the Aleutian Islands, sending a towering ash cloud 35,000ft into the sky and sparking an alert for aviation for the second straight day.
The Alaska Volcano Observatory issued its highest alert level after the Bogoslof volcano erupted.
Observatory volcanologist Robert McGimsey said Wednesday's eruption was "almost a carbon copy" of one which took place 24 hours earlier.
He said both eruptions prompted the highest alert level, though both were downgraded hours after the events.
Tuesday's eruption sent ash and steam 34,000ft into the air, while Wednesday's burst soared 1,000ft higher. Officials say both volcanic explosions were also short-lived.
The observatory said it is reducing the alert level because there had been no recent volcano activity.
The volcano is located on an island of the same name in the Bering Sea, about 850 miles south-west of Anchorage.
