Extremely high diversity of sulfate minerals in caves of the Irazú Volcano (Costa Rica) related to crater lake and fumarolic activity
(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 ...
Comparación de la composición química de partículas PM10 y PM2,5 colectadas en ambientes urbanos y zonas volcánicas del área metropolitana de Costa Rica
(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 ...
Co-ideation of disaster preparedness strategies through a participatory design approach: Challenges and opportunities experienced at Turrialba volcano, Costa Rica
(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 ...
Relationship between Diffuse CO2 Degassing and Volcanic Activity. Case Study of the Poás, Irazú, and Turrialba Volcanoes, Costa Rica
(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 ...
Mechanisms of Unrest and Eruption at Persistently Restless Volcanoes: Insights From the 2015 Eruption of Telica Volcano, Nicaragua
(Advancing Earh and Space Science, 2019)
Many of Earth's volcanoes experience well‐defined states of “quiescence” and “unrest,” with unrest occasionally culminating in eruption. Some volcanoes, however, experience an unusually protracted (i.e., decades‐long) ...
Transport properties of glassy and molten lavas as a function of temperature and composition
(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 ...
Magmatic volatiles in ash leachates and environmental impact assessment of the 29-30 October 2014 eruption of Turrialba volcano
(The International Union of Geodesy and Geophysics (IUGG), 2015-06)
Resumen de presentación sobre volátiles magmáticos en lixiviados de cenizas y evaluación de impacto ambiental de la erupción del volcán Turrialba del 29 al 30 de octubre de 2014 en la 26th IUGG General Assembly
Renewed Explosive Phreatomagmatic Activity at Poás Volcano, Costa Rica in April 2017
(Frontiers in Earth Science, 2018-10-16)
Phreatic and phreatomagmatic eruptions at volcanoes often present no short termprecursory activity, making them a challenge to forecast. Poás volcano, Costa Rica, exhibits cyclic activity with phreatic and some phreatomagmatic ...
