Emplacement processes of the Soufriere Hills dome (Montserrat) can be discerned using thermal infrared (TIR) wavelengths, which are sensitive to changes in temperature flux and emissivity variations over time. With the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), one cloud-free image is captured every three months on average, with increased frequency in 2002, when the volcano was a high priority target. Montserrat Volcano Observatory weekly reports from 1999 to present (available online) were also ingested into a multi-parameter, searchable database. These data, which detail specific volcanic activity, were compared against the ASTER data. The database fields include SO2 flux, GOES-derived radiance measurements, description of dome growth and collapse, and intensities of pyroclastic flows, rockfalls, fumarolic activity, and seismic activity. This database provides a unique cross-reference for the interpretation of the spaceborne data, as well as highlighting observable trends in each of the volcanic activity types. We hope to apply this methodology in the prediction and monitoring efforts of active dome hazards elsewhere.
