Stereo Image of Mount Redoubt
January 25, 2011
The 3-D image above shows fumarolic activity on Mount Redoubt’s north flank, an active, stratovolcano volcano west of Cook Inlet, on the Kenai Peninsula of Alaska. These fumaroles are associated with its most recent eruptive activity two years ago. Mount Redoubt, looming approximately 9,000 ft (2,700 m) above the surrounding terrain, has had five noteworthy eruptions during the past 110 years. On January 30, 2009, a sequence of oblique photos of Redoubt Volcano were taken during an observation flight. Two of these photos happened to form a stereo pair and were thus used to create the above anaglyph image. The view is from the west. You can view the full resolution individual images here: Left Image, Right Image.
Image details: Anaglyph was prepared by William L. Chamberland; photogrammetrist and emeritus member of the American Society for Photogrammetric and Remote Sensing. It was created using Anaglyph Maker V1.08 software by Takashi Sekitani. Image is adjusted for an average depth of view and is parallax free at the center. Original images are courtesy of the Alaska Volcano Observatory and the U.S. Geological Survey -- they were acquired by photographer Kristi Wallace.
