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 ...
Thermoplasmatales and sulfur‑oxidizing bacteria dominate the microbial community at the surface water of a CO2‑rich hydrothermal spring located in Tenorio Volcano National Park, Costa Rica
Here we report the chemical and microbial characterization of the surface water of a CO2-rich hydrothermal vent known in Costa Rica as Borbollones, located at Tenorio Volcano National Park. The Borbollones showed a temperature ...
Geophysical, geochemical and geodetical signals of reawakening at Turrialba volcano (Costa Rica) after almost 150 years of quiescence
Turrialba is a basaltic–andesitic stratovolcano (3340 masl), in the Cordillera Volcánica Central in Costa Rica. After the last eruption (1864–1866), volcanic manifestations were limited to weak fumarolic discharge (continuous ...
Gas measurements from the Costa Rica–Nicaragua volcanic segment suggest possible along-arc variations in volcanic gas chemistry
Obtaining accurate estimates of the CO2output from arc volcanism requires a precise understanding of the potential along-arc variations in volcanic gas chemistry, and ultimately of the magmatic gas signature of each ...
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
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 ...
Isla del Coco, on Cocos Plate, converges with Isla de San Andrés, on the Caribbean Plate, at 78mm/yr
(Revista de Biologia Tropical, 2012-11)
Isla del Coco is the only land mass of the Cocos Plate that emerges above sea level. This makes it the only place where Cocos Plate motion can be measured using Global Navigation Satellite System (GNSS) monitoring. Global ...
New insights into Kawah Ijen’s volcanic system from the wet volcano workshop experiment
(Geological Society London Special Publications, 2016-02-25)
Volcanoes with crater lakes and/or extensive hydrothermal systems pose significant challenges with respect to monitoring and forecasting eruptions, but they also provide new opportunities to enhance our understanding of ...
