Information about Activity at Redoubt Volcano
On June 30 AVO lowered the Aviation Color Code and Volcano Alert Level to Yellow and Advisory at Redoubt volcano based on a significant decrease in the rate of lava extrusion. Between March 22nd and April 4th 2009, Redoubt produced multiple significant explosions that sent ash and gas clouds to as high as 65,000 feet (19.8 km) above sea level and significantly disrupted air traffic. After April 4th, the eruption continued with extrusion of a lava dome within the summit crater, eventually producing a blocky lava flow down the north flank of the volcano. For the most up-to-date information, please see the Redoubt Activity Page.
