Caption:Looking west over the southwest caldera floor at one of the pre-caldera stratocones partially destroyed in the caldera-forming eruption 9,400 years ago. The southern flanks of Turquoise Cone are seen on the right. The low bench in the middle of the image may be the portions of Turquoise Cone that developed below the surface of the intra-caldera lake.

Caption:Looking northwest from south caldera rim across the southern caldera floor to the drainage from Turquoise Lake. Eickelberg Peak is in the background on the right. The collapsed remains of Turquoise Cone are just out of the image on the left.

Caption:Looking north over the northern caldera wall. The light tan portion of the wall has been altered to clay, likely due to older fumarolic activity, similar to what is seen today on Mt. Finch ~5 km to the south. The dark areas in the foreground are basaltic scoria deposits from a cinder cone just outside the field of view to the west (left). The stream valleys empty into the western caldera lake.

Caption:Looking south at the southern caldera rim from above Turquoise Cone. This prominent portion of the southern caldera wall represents a pre-caldera stratocone that was almost entirely destroyed in the caldera-forming eruption 9,400 years ago. The stream in the middle ground drains the southern half of the caldera, flowing southwest (right) through the southern outflow canyon, a 100-m deep, 500-m wide break in the caldera wall.

Caption:Just south of the southeastern caldera rim looking west across the southern caldera wall of Fisher volcano. AVO scientist Dr. Jim Gardner investigates an older basaltic lava flow. The low area on the right is the southern caldera floor, and the snow-free peak on the right is one of the stratocones partially destroyed in the caldera-forming eruption 9,400 years ago. The snow covered peaks in the background are Westdahl (left) and Faris Peak.

Caption:Deposits from the caldera-forming eruption 9,400 years ago, about 5 kilometers outside the eastern caldera wall. AVO scientist Dr. Jim Gardner stand at the base of ~6.5 meters of pumice fall, capped by ~2.5 m of densely welded pyroclastic flow material. Additional pyroclastic flow material above is obscured by slope wash.

AVO scientist Dr. Jim Gardner stands near the base of ~6.5 meters of pumice fall, capped by ~2.5 m of densely welded pyroclastic flow material. Additional pyroclastic flow material above is obscured by slope wash. In the foreground is the top of the welded portion of pyroclastic flow deposit.

Caption:Novarupta Dome, upper Valley of Ten Thousand Smokes, Katmai National Park and Preserve, Alaska. The 380-m-wide rhyolite lava dome marks the center of the vent of the great eruption of 1912, and formed in the weeks to months following the June 6-9 explosive eruption. The vent itself is roughly 2 km wide and was backfilled by welded ash-flow tuff and fallback ejecta during the eruption.

Caption:False color composite satellite image of an eruption of Mount Shishaldin volcano in 1999. The volcano is located on the central part of Unimak Island just west of the Alaska Peninsula of Alaska. This was one of the first volcanic eruptions that was observed by the Landsat 7 ETM+ satellite. Composite produced with a Red-Green-Blue channel combination of Band 4 - Band 3 - Band 2 respectively. This combination produces an image that displays vegetation in red. Lahars, also known as mud flows can be seen on the northern flank of the volcano. The ash plume from this eruption can be seen extending to the south and is very ash rich from the dark coloration. Ash deposits can also be seen on the east and southeast sides of the volcano. Produced by Steve J. Smith, Volcanology/Remote Sensing Graduate Student from the Geophysical Institute University of Alaska Fairbanks, the College of Science, Engineering, and Mathematics, and the Alaska Volcano Observatory. Image was run through a linear 0-255 enhancement.
