    • A brittle failure model for long-period seismic events recorded at Turrialba Volcano, Costa Rica 

      Eyre, Thomas; Bean, Christopher; DE BARROS, LOUIS; Martini, Francesca; Lokmer, Ivan; Mora Fernández, Mauricio Manuel; Pacheco, Javier F.; Soto, Gerardo J. (American Geophysical Union, 2015-01-30)
      A temporary seismic network, consisting of 23 broadband and six short-period stations, wasinstalled in a dense network at Turrialba Volcano, Costa Rica, between 8 March and 4 May 2011. During thistime 513 long-period (LP) ...

    • 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 ...

    • Middle to Late Miocene Contractional Deformation in Costa Rica Triggered by Plate Geodynamics 

      Mescua, José Francisco; Porras, Hernán; Durán, Patrick; Giambiagi, Laura; Maarten de Moor, J; Cascante, Monserrat; Protti, Marino; Poblete, Fernando (AGU Publications, 2017-12-11)
      Contractional deformation in Costa Rica is usually attributed to the subduction of the aseismic Cocos Ridge. In this work, we review the evidences for contraction in the middle to late Miocene, prior to the arrival of the ...

    • 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 ...
