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."

GREAT SITKIN (VNUM #311120)
52°4'35" N 176°6'39" W, Summit Elevation 5709 ft (1740 m)
Current Volcano Alert Level: WATCH
Current Aviation Color code: ORANGE

Slow eruption of lava in the summit crater of Great Sitkin Volcano continues. Small long-period and volcano-tectonic earthquakes continue to occur beneath the volcano. Webcam and satellite views of the volcano were obscured by clouds over the past day. 

The current lava flow eruption began in July 2021. No explosive events have occurred since a single event in May 2021.

Local seismic and infrasound sensors and web cameras are used to monitor Great Sitkin along with regional infrasound and lightning networks and satellite data.



SHISHALDIN (VNUM #311360)
54°45'19" N 163°58'16" W, Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color code: YELLOW

Unrest at Shishaldin Volcano continues. Small, low-frequency earthquakes occurred throughout the day. Satellite and webcam views were mostly cloudy. 

Minor rock falls associated with collapse events from the unstable ground in and near the summit crater may generate very small clouds of fine-grained ash that dissipate quickly and leave behind local deposits in the immediate vicinity of the summit. The last significant ash-producing eruption occurred in November 2023. 

Local seismic and infrasound sensors, web cameras, and a geodetic network are used to monitor Shishaldin Volcano. In addition to the local monitoring network, AVO uses nearby geophysical networks, regional infrasound and lighting data, and satellite images to detect eruptions.
