(IAVCEI Commission on Volcano Lakes, 2019-03)
Resumen de la ponencia: Poás volcano: significance of mobile trace elements in the hyperacid crater lake
Seismic activity at Irazú volcano after the 5th September 2012 Nicoya, Earthquake, Costa Rica
(2013)
Póster sobre actividad sísmica en el volcán Irazú después del terremoto del 5 de septiembre de 2012 en Nicoya, Costa Rica
The opening of vents like decompression valves of the hydrothermal system at Turrialba volcano, Costa Rica
(International Association of Volcanology and Chemistry of the Earth's Interior, 2013-07-24)
Thin-skinned mass-wasting responsible for widespread deformation at Arenal volcano
(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 ...
Short-period volcanic gas precursors to phreatic eruptions: Insights from Poás Volcano, Costa Rica
(Elsevier, 2016-03)
Volcanic eruptions involving interaction with water are amongst the most violent and unpredictable geologic phenomena on Earth. Phreatic eruptions are exceptionally difficult to forecast by traditional geophysical techniques. ...
Insights on Hydrothermal‐Magmatic Interactions and Eruptive Processes at Poás Volcano (Costa Rica) From High‐Frequency Gas Monitoring and Drone Measurements
(AGU Publications, 2019-02-06)
Identification of unambiguous signals of volcanic unrest is crucial in hazard assessment. Processes leading to phreatic and phreatomagmatic eruptions remain poorly understood, inhibiting effective eruption forecasting. Our ...
La actividad explosiva del volcán Turrialba (Costa Rica) en el período 2010 - 2016
(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 ...
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 ...
