Mount Pavlof sits in the southwestern end of the Alaska Peninsula and is one of the most active volcanoes in the United States with more than 40 recorded eruptions. The most recent volcano eruptions were in mid-May and March when it sent ash plumes as high as 20, 0000 feet.
The volcano is again showing signs of unrest which has forced the Alaska Volcano Observatory to closely monitor the activity and behavior of the volcano.
“Pavlof is one of those volcanoes that can erupt without very much in the way of precursory activities. It’s very easy for the magma to arise in the volcano and make it out. So even subtle signs of unrest we think it is prudent to increase our alert level.” Geophysicist David Schneider told Alaskan radio station KUCB.
Scientists describe volcano activity on the basis of the level of unrest and "Advisory" or "Yellow" warning signs reflect elevated unrest. It could turn "Red" or "Warning" if a higly hazardous eruption is underway or imminent.

Mount Pavlof is about 7km in diameters and has been actively spewing out lava since 1980s. After its eruption in 1996, the volcano went into the state of dormancy which was ended on August 2007 with the vigorous eruption of lava.
