Mount Cleveland Spews "Weak Plume"

Alexandra Gutierrez, KUCB - UnalaskaOver the weekend,  the Mount Cleveland volcano burped out an ash plume.  Steve McNutt at the University of Alaska-Fairbanks  Alaska Volcano Observatory calls it a "weak" plume.AVO had already placed Cleveland on yellow status, then dropped that down, but now it's back on yellow, and its plumes in the central Aleutians - which tend to come out several times a year - can be a hazard to local aviation at around ten thousand feet and lower.The plume did not reach high enough to affect trans-pacific jet aviation.Download Audio (MP3)
