This study investigates five eruptions with different temporal trends of erupted mass and sulfur dioxide (SO2) at Piton de la Fournaise (La Réunion). We acquired the daily SO2 emissions from three ultraviolet (UV) satellite instruments (the Ozone Monitoring Instrument [OMI], the Ozone Mapping and Profiler Suite [OMPS] and the Tropospheric Monitoring Instrument [TROPOMI]). The Time-Averaged-Lava-Discharge Rate (TADR) has been obtained from two automatic systems: MIROVA and MODVOLC. Assuming that the lava volumes measured in the field are the most accurate, MIROVA gives the best estimation among all the methods investigated. It has also been demonstrated that a petrological approach …

Linking Historical, Field, And Satellite Data To Determine The Relationship Between Gas Emissions And Vegetation Change In The Puhimau Geothermal Area East Rift Zone Kilauea, Hawaii, Christie Torres Rosa
Dissertations, Master's Theses and Master's Reports
The Puhimau geothermal area, located near the summit of the Kilauea volcano, Hawaii, has been suggested to represent a ‘window’ into the East Rift Zone. The quantification of CO2 and H2S soil gas emissions improves our understanding of its gas emission mode- including total emission and spatial distribution and contribute to a more accurate estimation of total CO2 and H2S in the thermal area – and how these gas emissions relate to observed vegetation health from satellite data. The total emission of CO2 and H2S was interpolated by the sequential Gaussian …
