French geologist Pierre Gauthier, who collaborates with Sims to gather and analyze volcanic gases, works from the rim collecting gas in a homemade device crafted from a noisy handheld vacuum cleaner powered by a motorcycle battery. ?In France, money for volcanology is tight these days,? Gauthier said. ?So we have to have a lot of ingenuity.? Gauthier, a specialist in volcanic gases, originally introduced Sims to Masaya Volcano, and he conducted pioneering research to measure time scales of magma degassing. Gauthier works for the Laboratoire Magmas et Volcans, operated by the Centre National de la Recherche Scientifique at the University of Clermont-Ferrand. (Photo by Amy E.
