SummaryWe propose to acquire TerraSAR-X Spotlight mode amplitude imagery over the Soufrière Hills Volcano (SHV), Montserrat. SHV is currently in a period of low activity, such that there is no growth of the lava dome. However, indications are that dome growth will recommence in the short- to medium-term future. At present, the large lava dome is undergoing natural degradation by erosion, generating rockfalls and occasional pyroclastic flows, resulting in morphological and structural changes. High resolution imagery from TerraSAR-X will initially be used to map the features of the lava dome. Following this, a time series of images will be used to identify and track morphological and structural changes related to the natural degradation of the dome, or the intrusion of new magma into shallow levels in the volcano. In addition, the imagery will be used for mapping of the spatial distribution of rockfall and pyroclastic flow deposits associated with renewed dome growth. All this information will be used by the Montserrat Volcano Observatory (MVO) in routine hazard assessments. Our project will run for 2 years during which time we wish to acquire 82 scenes. We will report the findings of the work in international journals e.g. Journal of Volcanology and Geothermal Research and at major conferences. This proposal is a follow-up to Project GEO0436 that successfully proved the operational viability of using TerraSAR-X imagery at the MVO as part of routine hazard assessments. This work is funded by the Montserrat Volcano Observatory.
