In late May, 2009, activity decreased and the Alaska Volcano Observatory lowered the alert level. A nearly six-month period of relative quiet at the volcano ended on December 27, 2009, with renewed earthquake swarms. The AVO subsequently raised the alert level, and again warned of the possibility of a more vigorous eruption due to dome collapse ...
The Observatory website allows users to monitor active volcanoes, with seismographs and webcameras that update regularly. AVO now monitors more than 20 volcanoes in Cook Inlet , which is close to Alaskan population centers, and the Aleutian Arc due to the hazard that plumes of ash pose to aviation.
Redoubt volcano in eruption. Redoubt is the park's active volcano. 10,197 feet (3,108 m) high, about 10 kilometres (6.2 mi) in diameter and with a volume of about 30 to 35 cubic kilometers, the stratovolcano rises through the Chigmit batholith. It has a 1.8-kilometre (1.1 mi) wide summit crater.
The Alaska Volcano Observatory currently rates Douglas as Level of Concern Color Code Not Assigned. The volcano has a warm and highly acidic crater lake approximately 160 m (525 ft) wide. In 1982, the lake had a temperature of 21 °C and a pH of 1, and temperatures of 114-118°C were measured in 1991. At the north flank of the volcano ...
The National Volcano Early Warning and Monitoring System has two purposes: [11] To "organize, modernize, standardize, and stabilize the monitoring systems of the volcano observatories in the United States, which includes the Alaska Volcano Observatory, California Volcano Observatory, Cascades Volcano Observatory, Hawaiian Volcano Observatory, and Yellowstone Volcano Observatory".
