Instability and Collapse of Lava Domes and Volcano Flanks
We are investigating modes and triggers for the hazardous collapse of lava domes, and the flanks of volcanoes, often driven by the presence of overpressured volcanic fluids. These investigations include the lateral collapses on the Canary and Cape Verde Islands, and dome collapses on Soufriere Hills volcano on Montserrat, and on Merapi, and Unzen. In particular, the effort includes using unique precision geodetic data from an array of strainmeters, seismometers, tiltmeters and cGPS permanently-deployed at Soufriere Hills volcano - the CALIPSO project.
