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 ... -
Co-ideation of disaster preparedness strategies through a participatory design approach: Challenges and opportunities experienced at Turrialba volcano, Costa Rica
Van Manen, Saskia; Avard, Geoffroy; Martínez-Cruz, María (Elsevier, 2015)Disaster preparedness is key to coping and adaptation during the immediate aftermath of a natural hazard, but the majority of those at risk do not feel prepared. In this participatory action research we investigate the ... -
Comparación de la composición química de partículas PM10 y PM2,5 colectadas en ambientes urbanos y zonas volcánicas del área metropolitana de Costa Rica
Herrera, Jorge; Rojas, José Félix; Martínez, María; Avard, Geoffroy; De Moore, Martin; Sáenz, Wendy; Beita, Víctor H.; Rodríguez, Agustín; Agüero, Alejandro (Revista Ciencias Ambientales, 2014-12)Se muestrearon, en forma simultánea, partículas PM10 y PM2,5 en ambientes urbanos y volcánicos del área metropolitana de Costa Rica, durante octubre y noviembre de 2012. En las áreas industriales y comerciales de alto flujo ... -
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 ... -
Insights Into the Mechanisms of Phreatic Eruptions From Continuous High Frequency Volcanic Gas Monitoring: Rincón de la Vieja Volcano, Costa Rica
Battaglia, Angelo; de Moor, Joost Maarten; AIUPPA, Alessandro; Avard, Geoffroy; Bakkar, Henriette; BITETTO, Marcello; Mora Fernández, Mauricio Manuel; Kelly, Peter; Giudice, Gaetano; Delle Donne, Dario; Villalobos, Hairo (Frontiers Media, 2019-01-11)Understanding the trigger mechanisms of phreatic eruptions is key to mitigating the effects of these hazardous but poorly forecastable volcanic events. It has recently been established that high-rate volcanic gas ... -
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 ... -
Thin-skinned mass-wasting responsible for widespread deformation at Arenal volcano
Ebmeier, Susanna; Biggs, Juliet; Muller, Cyril; Avard, Geoffroy (Frontiers Media, 2014-12-03)The shape and stability of a volcano’s edifice depends on the relationship between eruption rate and the loss or redistribution of material due to erosion, mass-wasting or deformation. This work provides measurements of ... -
Transport properties of glassy and molten lavas as a function of temperature and composition
Hofmeister, Anne M.; Sehlke, Alexander; Avard, Geoffroy; Bollasina, Anthony J.; Robert, Geneviève; Whittington, Alan (Elsevier, 2016-11-15)We provide measurements of thermal diffusivity (D), heat capacity (CP), and viscosity (η) for 12 remelted natural lavas and 4 synthetic glasses and melts, ranging in composition from leucogranite to low-silica basalt, and ...
