Eruption news from Cleveland volcano:
Cleveland volcano (Aleutian Islands, Alaska) activity update
Thursday Jun 06, 2013 12:05 PM | VON: T
There have been no explosions detected from Cleveland volcano since May 6, and there is no evidence for lava effusion since May 13. Weakly elevated surface temperatures detected in clear-weather satellite views are consistent with cooling of a newly emplaced lava flow.
AVO has therefore lowered the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory.
