A New Sulfur and Carbon Degassing Inventory for the Southern Central American Volcanic Arc: The Importance of Accurate Time-Series Data Sets and Possible Tectonic Processes Responsible for Temporal Variations in Arc-Scale Volatile Emissions
(AGU Publications, 2017-12-12)
This work presents a new database of SO2 and CO2 fluxes from the Southern Central American Volcanic Arc (SCAVA) for the period 2015–2016. We report 300 SO2 flux measurements from 10 volcanoes and gas ratios from 11 volcanoes ...
Insights Into the Mechanisms of Phreatic Eruptions From Continuous High Frequency Volcanic Gas Monitoring: Rincón de la Vieja Volcano, Costa Rica
(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 ...

Eruptive activity at Turrialba volcano (Costa Rica): Inferences from 3He/4He in fumarole gases and chemistry of the products ejected during 2014 and 2015
(AGU Publications, 2016)
A new period of eruptive activity started at Turrialba volcano, Costa Rica, in 2010 after almost 150 years of quiescence. This activity has been characterized by sporadic explosions whose frequency clearly increased since ...
Poás volcano: Geophysical-Geochemical signatures and dynamics of its magmatic-hydrothermal system
(International Association of Volcanology and Chemistry of the Earth's Interior, 2014-09)
Poás volcanic complex hosts a hyper-acid lake where geochemical signatures are related to two major controlling processes: (a) The level of inux and dissolution-hydrolysis of magmatic volatiles in a sub-surface hydrothermal ...
Magmatic volatiles in ash leachates and environmental impact assessment of the 29-30 October 2014 phreatic eruptions of Turrialba Volcano, Costa Rica
(The International Union of Geodesy and Geophysics (IUGG), 2015)
