Oblique Photogrammetric Analysis Of Dome Growth At Mount St. Helens Volcano, 2004 – 2007, Angela K. Diefenbach
WWU Graduate School Collection
This project is an oblique photogrammetric survey of the 2004-2007 dome-building eruption of Mount St. Helens volcano with two primary objectives: (1) to evaluate the potential of a new rapid and low-cost technique to create digital elevation models (DEMs) and subsequently calculate dome volumes and extrusion rates at Mount St. Helens; and (2) to attempt to understand mechanics associated with lava dome extrusion and collapse by analyzing volumetric and extrusion rate measurements in the context of dome height measurements, seismicity data, and migration of the locus of dome growth.
The new method uses sets of oblique aerial photographs, acquired from …
