The current eruption phase began on 23 July 2019 and through September included lava fountaining, explosions, and a lava lake in the summit crater. A small steam plume from the summit was observed over the past 24 hours. The Alaskan Volcano Observatory (AVO) report that the eruptive activity continues at Shishaldin volcano. Shishaldin reported activity, including all types of volcanic activity. The Aviation Color Code was raised to RED and the volcano Alert Level to WARNING at 17:28 UTC. Continuing activity during October 2019 through January 2020 is described in this report based largely on Alaska Volcano Observatory (AVO) reports, photographs, and satellite data. The current eruption phase began on 23 July 2019 and through September included lava fountaining, explosions, and a lava lake in the summit crater. Shishaldin Volcano erupting on January 6, 2020, as seen from Cold Bay, about 58 miles northeast of Shishaldin. Last eruption: January 3, 2020: Climbing; First ascent: May 16, 1932 by G. Peterson et al. The volcano is a symmetric cone with a base diameter of approximately 10 miles. Alaska's Shishaldin Volcano stained a large area of snowpack after an eruption last weekend sent ash thousands of feet into the sky.

Designated: 1967: Mount Shishaldin (/ ʃ ɪ ˈ ʃ æ l d ən /) is a moderately active volcano on Unimak Island in the Aleutian Islands chain of Alaska. Minor explosive activity has subsided over the past 24 hours, but seismicity remains elevated with near-continuous tremor.
Shishaldin (Aleutian Islands, Alaska): Shishaldin Volcano erupts on January 6, 2020, as seen from Cold Bay, 58 mi NE of the volcano. The Alaska Volcano Observatory has reported a large eruption on Mount Shishaldin, a 2870 m stratovolcano (cone-shaped volcano made up of layers of ash and lava), located on Unimak Island in the Aleutian Island Chain. The ash-producing explosion at Shishaldin Volcano, about 680 miles (1,094 km) southwest of Anchorage, marked the biggest event in about six months of the on-and-off eruption activity at the mountain, the Alaska Volcano Observatory reported. Continuing activity during October 2019 through January 2020 is described in this report based largely on Alaska Volcano Observatory (AVO) reports, photographs, and satellite data. Starting at about 09:30 UTC (00:30 AKST) on January 19, 2020, the eruption at Shishaldin volcano in Alaska intensified, and about 13:30 UTC began generating a more ash-rich volcanic plume. (first recorded ascent) Easiest route: East face:snow/glacier climb : U.S. National Natural Landmark.
AVO runs these models when a volcano is restless by assuming a reasonable hypothetical eruption, in order to provide a pre-eruptive forecast of areas likely to be affected. Volcanic Ash Advisory (updated January 7, 2020).
The volcano began erupting some time before 9.50 am on Friday 3 January 2020 (when the eruption was first observed by a pilot), and produced an ash column that … Shishaldin Volcano is located near the center of Unimak Island.
During an ongoing eruption, AVO will update the forecast with actual observations (eruption start time and duration, plume height) as they become available.
