December 2, 2012 – Cleveland Volcano Status is Yellow: VOn 21 November AVO noted that no explosions at Cleveland had been detected since 10 November, nor evidence of renewed lava-dome growth. The Volcanic Alert Level was lowered to Advisory and the Aviation Color Code was lowered to Yellow. Elevated surface temperatures were detected in satellite imagery during 21-24 November. Clouds obscured satellite and web camera views during 25-27 November. Image above is from a prior eruption.
Geologic Summary. Symmetrical Mount Cleveland stratovolcano is situated at the western end of the uninhabited dumbbell-shaped Chuginadak Island in the east-central Aleutians. The 1,730-m-high stratovolcano is the highest of the Islands of Four Mountains group and is one of the most active in the Aleutians. Numerous large lava flows descend its flanks. It is possible that some 18th to 19th century eruptions attributed to Carlisle (a volcano located across the Carlisle Pass Strait to the NW) should be ascribed to Cleveland. In 1944 Cleveland produced the only known fatality from an Aleutian eruption. Recent eruptions from Mt. Cleveland have been characterized by short-lived explosive ash emissions, at times accompanied by lava fountaining and lava flows down the flanks.
Last camera image received December 1, 2012 12:54 PM
This camera is located on top of High Hill a few miles North of the village of Nikolski on the western end of Umnak Island. Mount Cleveland is approximately 45 miles from the camera. The summit of Mt. Cleveland is located at the center of the image. Mount Carlisle can be seen on the right edge of the image. Due to the typically bad weather in this area of the state, Mt. Cleveland and Mt. Carlisle won’t be visible very often.
