On the weekend, the Pavlof Volcano (a stratovolcano from the Aleutian Range, Alaska Peninsula), suddenly burst into flames, spewing ash across the air. According to the Alaska Volcano Observatory, the volcano continues to rumble and spew ash. The volcano’s plume of ash could bring down an aircraft. A large ash plume is now 37,000 feet up in the atmosphere and trails about 400 miles (650 km) to the northeast over the interior of Alaska. Alerts have been issued to airports and planes flying in this area. Pavlof Volcano in eruption, 3 AM, March 28th, 2016.

The Observatory stated that the Observatory has observed a steady plume of ash in satellite imagery, moving northeastwards across Alaska’s interior. Satellite image showing strong ash signal (blue) extending over 300 miles (500 km), north-northeast from Pavlof, 4: 19 am AKDT (12: 19 UTC), March 28, 2016. Image: www.avo.alaska.edu. Residents, pilots, and mariners in Cold Bay (37 southwest of the volcano reported seeing lava flowing from its summit crater. Scientists think volcanic mudflows could be a danger to the river valleys around the volcano’s flanks. About Pavlof volcano The Pavlof volcanic is an ice and snow-covered stratovolcano that lies about 592 mile (953km) southwest from Anchorage, at the southern end of Alaska Peninsula. The summit is approximately 4.4 miles (7 kilometers) wide. It has active vents on the east and northern sides. One of North America’s most active volcanoes, the Pavlof Volcano. It is not considered a danger to land dwellers because it’s located in such a remote location. It can cause engine damage to aircrafts flying through the ash plume. It is the Aleutian Arc’s most active volcano, with more than 40 historical eruptions. Subduction along the Aleutian Trench has resulted in a variety of dormant and active volcanoes. The volcano’s eruption causes lava to flow down its mountain, and it can do so for many months. Past eruptions have generated ash plumes as high as 49,000 feet. A 2013 eruption produced a 27,000-feet-high plume that extended 310 miles (500 km) from the volcano.

The threat score for this volcano is 95. Future eruptions are considered high. Large ash releases pose the greatest threat to airways near the volcano. According to Geology.com: “Each day at least 20,000 international airline passengers and dozens of flights loaded with freight fly above the volcano.” “An eruption at Pavlof that puts large amounts of volcanic ash high into the atmosphere produces air traffic safety concerns and significant financial losses as flights must be rerouted. Scientists pay a lot of attention to this volcano. Video: Pavlof Volcano erupted Sunday Ash could be seen in the atmosphere and cause engine failure or malfunction. All aircraft flying in this area have been alerted.
