La actividad explosiva del volcán Turrialba (Costa Rica) en el período 2010 - 2016
Brenes-André, José; Barrantes, Manuel; Vega, Eduardo; De Moor, J. Maarten; Avard, Geoffroy; Dellino, Pierfrancesco; Mele, Daniela; DeVitre, Charlotte; Di Piazza, Andrea; Rizzo, Andrea L.; Carapezza, Maria L.; Alvarado, Guillermo E. (Universidad de Costa Rica, 2016-12-18)The most recent eruptive activity of Turrialba volcano began on the 5th of January 2010, after more than a century of dormancy. The fragmentation process and aerodynamic behavior of the ash from Turrialba’s vulcanian ... -
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 ... -

Extremely high diversity of sulfate minerals in caves of the Irazú Volcano (Costa Rica) related to crater lake and fumarolic activity
Ulloa, Andrés; Gázquez, Fernando; Sanz-Arranz, Aurelio; Medina, Jesús; Rull, Fernando; Calaforra, José María; Alvarado, Guillermo E.; Martínez, María; Avard, Geoffroy; De Moor, J. Maarten; De Waele, Jo (International Journal of Speleology, 2018-05)The caves of the Irazú volcano (Costa Rica), became accessible after the partial collapse of the NW sector of the Irazú volcano in 1994, offering the opportunity to investigate active minerogenetic processes in volcanic ... -
Halogen activation in the plume of Masaya volcano: field observations and box model investigations
Rüdiger, Julian; Gutmann, Alexandra; Bobrowski, Nicole; Liotta, Marcello; De Moor, J. Maarten; Sander, Rolf; Dinger, Florian; Tirpitz, Jan-Lukas; Ibarra, Martha; Saballos, Armando; Martínez, María; Mendoza, Elvis; Ferrufino, Arnoldo; Stix, John; Valdés, Juan; Castro, Jonathan M.; Hoffmann, Thorsten (Atmospheric Chemistry and Physics, 2020)Volcanic emissions are a source of halogens to the atmosphere. Rapid reactions convert the initially emitted hydrogen halides (HCl, HBr, HI) into reactive species e.g. BrO, Br2, BrCl, ClO, OClO and IO. The activation ... -
Relationship between Diffuse CO2 Degassing and Volcanic Activity. Case Study of the Poás, Irazú, and Turrialba Volcanoes, Costa Rica
Epiard, Matthieu; Avard, Geoffroy; De Moor, J. Maarten; Martínez Cruz, María; Barrantes Castillo, Gustav; Bakkar, Henriette (Frontiers in Earth Science, 2017-10-11)Active volcanoes exhibit diffuse gas emanations through the ground, the most abundant species of which is CO2. However, the relationship between diffuse degassing and volcanic activity is not often clear and some volcanoes ...
