SummaryWe propose to use TSX images to study magmatic, tectonic and geothermal processes within Yellowstone that can lead to measureable surface deformation. The 11 day repeat time of the TSX platform and high spatial resolution should enable detailed studies within a summer season that cannot be conducted with available C and L band platforms. During a normal year, Yellowstone caldera is covered with snow from November through June effectively allowing good summer to summer studies of caldera deformation but only limited studies within one snow-free season. We aim to study the following phenomena with TSX data: 1) caldera-wide deformation, 2) geyser basin deformation, 3) earthquake swarm deformation and 4) possible deformation related to hydrothermal explosions.
