    • Are the ashes from the latest eruptions (2010–2016) at Turrialba volcano (Costa Rica) related to phreatic or phreatomagmatic events? 

      Mele, Daniela; Alvarado Induni, Guillermo E.; Dellino, Pierfrancesco; de Moor, Joost Maarten; Avard, Geoffroy (Elsevier, 2016-09-15)
      The initial eruptive episodes of explosive eruptions are classified as phreatic if the amount of juvenile material (scoria, glass, pumice) is null, and the amount of fresh accidental lithics, and hydrothermally altered ...

    • Carbon and sulfur isotopes in tree rings as a proxy for volcanic degassing 

      D’Arcy, Fiona; Boucher, Étienne; De Moor, J. Maarten; Hélie, Jean-François; Piggott, Robert; Stix, John; de Moor, Joost Maarten; Hélie, Jean-François (Geological Society of America, 2019-07-05)
      Trees are useful archives of past atmospheric conditions. They have most commonly been used to infer large-scale changes in climate, industrial pollution, and the magnitude and frequency of geological hazards. While ...

    • Carbon isotope systematics of Turrialba volcano, Costa Rica, using a portable cavity ring-down spectrometer 

      Stix, J.; Chu, K.; Sherwood Lollar, B.; Malowany, Kalina; de Moor, Joost Maarten; Lacrampe-Couloume, Georges (AGU Publications, 2017-07-27)
      Over the past two decades, activity at Turrialba volcano, Costa Rica, has shifted from hydrothermal to increasingly magmatic in character, with enhanced degassing and eruption potential. We have conducted a survey of the ...

    • Drones Swoop in to Measure Gas Belched from Volcanoes 

      D’Arcy, Fiona; Stix, John; Rüdiger, Julian; Diaz, Jorge Andrés; Alan, Alfred; de Moor, Joost Maarten; Corrales, Ernesto (EOS. Science News by AGU, 2018-07-25)
      Los gases volcánicos son importantes herramientas de pronóstico de erupciones que se utilizan a menudo en el monitoreo de volcanes. Sin embargo, la recolección de muestras de gas requiere que los científicos ingresen a ...

    • Fluid geochemistry and seismic activity in the period 1998-2002 at Turrialba Volcano: Costa Rica 

      Tassi, Franco; Vaselli, Orlando; Barboza, Vilma; Fernández, Erick; Duarte, Eliecer (Universidad de Florencia, Italia, 2004)
      Turrialba Volcano, located in Central-Southern Costa Rica, has been characterized, since the last period of eruptive activity in 1884-1886, by a weak and discontinuous fumarolic activity in the western area of its summit. ...

    • Space- and ground-based measurements of sulphur dioxide emissions from Turrialba Volcano (Costa Rica) 

      Campion, Robin; Martínez-Cruz, María; Pacheco, Javier; Campion, Robin; Lecocq, Thomas; Caudron, Corentin; Pinardi, Gaia; Hermans, Christian; Carn, Simon; BERNARD, Alain (Springer Verlag, 2012-06-21)
      Remotely sensed measurements of sulphur dioxide (SO2) emitted by Turrialba Volcano (Costa Rica) are reported for the period September 2009–January 2011. Thesemeasurements were obtained using images from Advanced Spaceborne ...
