Deformation History

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


Deformation during 1995 - 2010 [Uplift; Observed by InSAR]

Start Date: 1995 Stop Date: 2010 Direction: Uplift Method: InSAR
Magnitude: Unknown Spatial Extent: 20.00 km Latitude: 58.000 Longitude: -155.000

Remarks: A deformation signal near Martin, Mageik, and Trident volcanoes has been observed with InSAR. There is a gap in InSAR data coverage between 2000 and 2004, but the uplift is likely continuous.

Figure (see Caption)

Averaged deformation images of the Mount Martin?Mount Mageik area produced by stacking high- quality ERS-1 and ERS-2 interferograms for 1995?2000 from two ascending tracks, 021 and 250. Ellipse outlines an area of subsidence near Novarupta dome. A full cycle of colors (i.e., one interferometric fringe) represents 28 mm/year of LOS surface displacement. Areas of loss of InSAR coherence are not colored. See Fig. 6.197 for meanings of labels

Photo Gallery

Mount Mageik is the broad stratovolcano at the center of this aerial view from the east, south of Katmai Pass. Martin volcano forms the skyline left of Mageik, and lava flows on the flanks of Trident volcano are visible at the middle right. The three volcanoes are part of a NE-SW volcanic chain cutting across Katmai National Park. Much of the surface of Mageik volcano is formed by lava flows of Holocene age. Historical reports of eruptions from both Mageik and Martin are of variable reliability.

Mount Mageik (left) and steaming Mount Martin (distant right) tower above the flat-bottomed floor of the Valley of Ten Thousand Smokes (VTTS). The VTTS was formed by ash flows during the 1912 eruption of Novarupta volcano, the Earth's largest eruption of the 20th century. Glacier-clad Mount Mageik has a broad summit capped by 4 knobs, each of which is a spatter and lava-flow vent.
