Kanaga Volcano is back to normal, according to the Alaska Volcano Observatory.  Scientists at the observatory lowered the alert level for the Aleutian volcano on Friday morning, saying in a release that, “the level of unrest has declined to background levels.”

On February 18 the Observatory issued an advisory after detecting tremors and a small ash cloud in the vicinity of Kanaga.  The volcano lies on a major international flight path and its last eruption in 1994 produced ash clouds that affected air travel to the nearby community of Adak. 

The Aleutian’s other restless volcano – the Cleveland – remains at aviation alert level orange or “watch” even though the dome in the summit crater has not grown in recent days.  Cleveland also lies on a major flight path and sent up an ash plume in December.
