Tara Shreve is interested in applying analytical and numerical models to study crustal deformation due to volcanic processes. She primarily uses ground deformation measurements from Interferometric Synthetic Aperture Radar (InSAR). Ground deformation at active volcanoes can occur due to a range of physical processes— including magma injection and transport, as well as gas exsolution and emission. Geodetic modelling alone cannot decipher between the possible physical processes driving deformation, although this knowledge is essential for assessing the likely outcomes of volcanic unrest episodes and the potential for an eruption. 

At Carnegie, Tara works with Dr. Hélène Le Mevel to integrate InSAR measurements with data from satellite-based UV spectrometers measuring sulphur dioxide gas emissions at active island volcanoes in Vanuatu, located in the South Pacific. By combining these remote sensing measurements, she aims to estimate properties of the magma stored within the shallow crust to better understand the magmatic system and eruption characteristics. The use of satellite-based remote sensing allows for systematically studying volcanic unrest in remote regions such as Vanuatu, regardless of whether the location is too difficult or dangerous to access.
