ANCHORAGE- A brief explosion from Cleveland Volcano happened Monday night.
The Alaska Volcano Observatory reports the minor explosion occurred just after 7 p.m.
It’s issued an advisory alert level and yellow aviation code.
Researchers aren’t sure if an ash cloud was produced but said it’s unlikely. They said there was a similar explosion detected on Dec. 28.
The activity report from the AVO warns of more minor explosions which may produce ash clouds. It reports the clouds probably won’t extend very far from Cleveland but could produce fallout along the flanks.
The volcano is located along the Aleutian Islands.
