Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Douglas. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Douglas page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Deformation History

There is data available for 1 deformation periods. Expand each entry for additional details.


Deformation during 2005 - 2010 [Uplift; Observed by InSAR]

Start Date: 2005 Stop Date: 2010 Direction: Uplift Method: InSAR
Magnitude: 6.000 cm Spatial Extent: 15.00 km Latitude: 59.000 Longitude: -154.000

Remarks: An uplift signal between Fourpeaked and Douglas is either due to magma or isostatic rebound.

Figure (see Caption)

(Left column) Observed (a, c, e, g) deformation images of Fourpeaked and Douglas volcanoes from four InSAR images from four different tracks. (Right column) Modeled (b, d, f, h) deformation images for the corresponding interferograms in the left column, showing LOS displacements predicted by a Mogi source located *7 km BSL. A full cycle of colors (i.e., one interferometric fringe) represents 28 mm of LOS surface displacement. Areas of loss of InSAR coherence are not colored

The broad, glacier-covered Mount Douglas stratovolcano rises to 2140 m across Kamishak Bay as seen from Augustine Island to its NE. Douglas volcano anchors the northern tip of the Alaskan Peninsula. The rocks in the foreground are part of a young debris-avalanche deposit from Augustine volcano.

Mount Douglas, a dissected and largely ice-covered, 2140-m-high stratovolcano at the northern tip of the Alaska Peninsula, is viewed here from the north. The volcano contains a youthful-looking, fumarolically active summit crater filled by a warm, acidic lake, but the presence of Holocene lava flows or tephra deposits has not been confirmed.

The summit of 2140-m-high Douglas volcano on the northern tip of the Alaska Peninsula contains a warm and highly acidic crater lake approximately 160 m wide. An active fumarole field is also found on the shores of the crater lake of this glacier-covered stratovolcano.

Steam rises from an active fumarolic area on the north side (left center) of the summit lake at Douglas volcano on the northern tip of the Alaska Peninsula. The small, 160-m-wide crater is one of the few ice-free areas on Douglas volcano. In 1992, the lake had a pH of 1.1 and a temperature of 21 degrees Centigrade.
