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) ...
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 ...
Are the ashes from the latest eruptions (2010–2016) at Turrialba volcano (Costa Rica) related to phreatic or phreatomagmatic events?
(Elsevier, 2016-09-15)
The initial eruptive episodes of explosive eruptions are classified as phreatic if the amount of juvenile material (scoria, glass, pumice) is null, and the amount of fresh accidental lithics, and hydrothermally altered ...
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 ...
Gas emissions from the Hyper-Acid Crater Lake of Poás Volcano, Costa Rica
(The International Union of Geodesy and Geophysics (IUGG), 2015-06)
Resumen de la presentación sobre las emisiones de gases del lago del cráter hiperácido del volcán Poás, Costa Rica en la 26th IUGG General Assembly
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 ...
Magmatic volatiles in ash leachates and environmental impact assessment of the 29-30 October 2014 phreatic eruptions of Turrialba Volcano, Costa Rica
