Mt.Redoubt Volcano Location

Redoubt Volcano Location

Description

From Miller et al (1998): "Redoubt Volcano is a steep-sided cone about 10 km in diameter at its base and with a volume of 30-35 cubic kilometers. The volcano is composed of intercalated pyroclastic deposits and lava flows and rests on Mesozoic granitic rocks of the Alaska-Aleutian Range batholith (Till and others, 1993; 1994). It has been moderately dissected by the action of numerous alpine glaciers. A 1.8-km-wide, ice-filled summit crater is breached on the north side by a northward-flowing glacier, informally known as the Drift Glacier, which spreads into a piedmont lobe in the upper Drift River Valley. The most recently active vent is located on the north side of the crater at the head of the Drift glacier. Holocene lahar deposits in the Crescent River and Drift River valleys extend downstream as far as Cook Inlet."

The eruption of Pavlof Volcano continues. Strongly elevated surface temperatures corresponding to the active lava flow on the east flank of Pavlof were observed in satellite data throughout the week. Web camera views were mostly obscured throughout the week, but occasional clear views showed continued steam emissions. Clear satellite views on Wednesday, January 19 showed a lava flow and lahar extending 1.3 km and 4.4 km (0.8 and 2.7 miles) east of the volcano's summit, respectively. Elevated seismicity, consisting of periods of sustained tremor, was detected throughout the week, and minor explosive activity was recorded by local and regional infrasound sensors on Wednesday.

Periods of lava fountaining from the vent on the volcano’s upper southeast flank have been occurring since mid-November 2021. This activity has built a small cone and sent flows down the flank that melt the snow and ice and produce variable amounts of meltwater. The meltwater typically incorporates loose debris on the flank of the volcano and forms thin (
