AVO VOLCANO ACTIVITY NOTIFICATION
(1) VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA)
(2) Issued: (20081105/2352Z)
(3) Volcano: Redoubt (VNUM #313030)
(4) Current Color Code: YELLOW
(5) Previous Color Code:
(6) Source: Alaska Volcano Observatory
(7) Notice Number: 2008/A32
(8) Volcano Location: N 60 deg 29 min W 152 deg 44 min
(9) Area: Cook Inlet-South Central
(10) Summit Elevation: 10197 ft (3108 m)
(11) Volcanic Activity Summary: Over the past several months, AVO has detected potentially significant changes in gas emission and heat output from Redoubt Volcano. These changes are a departure from long-observed background activity, and therefore, AVO is raising the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY. There is no indication that an eruption is imminent or even certain. AVO is monitoring Redoubt closely and is making plans to install additional equipment on the volcano in the next several weeks.

(14) Remarks: Heavily ice-mantled Redoubt volcano is located on the western side of Cook Inlet, 170 km (106 mi) southwest of Anchorage and 82 km (51 mi) west of Kenai, within Lake Clark National Park. Redoubt is a stratovolcano which rises to 10,198 feet above sea level. Recent eruptions occurred in 1902, 1966-68, and 1989-90. The 1989-90 eruption produced mudflows, or lahars, that traveled down the Drift River and partially flooded the Drift River Oil Terminal facility. The ash plumes produced by the 1989-90 eruption affected international air traffic and resulted in about 5 mm (0.2 inches) of ash in Kenai and trace amounts of ash in Anchorage and other nearby communities.
