The 1730–1736 eruption on Lanzarote was one of the most significant volcanic eruptions to occur Canary Islands, with lavas covering over 200 km2. Globally, it is volumetrically third largest known subaerial basaltic fissure in past 1,100 years. Here we use Sentinel-1 and ENVISAT interferograms both ascending descending orbits construct a time series line-of-sight surface displacements calculate...

Active volcanism was (and potentially still is) an important process that shapes the Venus surface and its detection is a primary goal for planned VERITAS EnVision missions. Therefore, understanding lava flow emplacement timing on important. We adapt terrestrial PyFLOWGO thermorheological model to conditions assess effects channelized propagation. first initiate with basaltic parameters progres...

Abstract. Piton de la Fournaise, situated on La Réunion island (France), is one of the most active hot spot basaltic shield volcanoes worldwide, experiencing at least two eruptions per year since establishment volcanological observatory in 1979. Eruptions are typically fissure-fed and form extensive lava flow fields. About 95 % some ? 250 historical events (since first confidently dated eruptio...

Since 2004, the satellite-borne Ozone Mapping Instrument (OMI) has observed sulphur dioxide (SO2) plumes during both quiescence and effusive eruptive activity at Soufrière Hills Volcano, Montserrat. On average, OMI detected a SO2 plume 4-6 times more frequently during effusive periods than during quiescence in the 2008-2010 period. The increased ability of OMI to detect SO2 during eruptive peri...

We visited 51 lakes in Costa Rica as part of a broad-based survey to document their physical and chemical characteristics and how these relate to the mode of formation and geographical distribution of the lakes. The four oxbow lakes were low in elevation and tended to be turbid, high in conductivity and CO2, but low in dissolved O2; one of these, L. Gandoca, had a hypolimnion essentially compos...

Since 2003, 27 independent look angles have been acquired by ENVISAT’s Advanced Synthetic Aperture Radar (ASAR) instrument over the island of Hawai`i, allowing for the formation of thousands of interferograms showing deformation of the ground surface. On Kīlauea volcano, a transition from minor to broad-scale summit inflation was observed by interferograms that span 2003 to 2006. In addition, r...
