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 ...
Carbon and sulfur isotopes in tree rings as a proxy for volcanic degassing
(Geological Society of America, 2019-07-05)
Trees are useful archives of past atmospheric conditions. They have most commonly been used to infer large-scale changes in climate, industrial pollution, and the magnitude and frequency of geological hazards. While ...
Implementation of electrochemical, optical and denuder-based sensors and sampling techniques on UAV for volcanic gas measurements: examples from Masaya, Turrialba and Stromboli volcanoes
(European Geosciences Union, 2018-04-26)
Volcanoes are a natural source of several reactive gases (e.g., sulfur and halogen containing species) and nonreactive gases (e.g., carbon dioxide) to the atmosphere. The relative abundance of carbon and sulfur in volcanic ...
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 ...
Crustal Thickness Along the Central American Volcanic Arc
(American Geophysical Union, 2004)
Resumen de ponencia "Crustal Thickness Along the Central American Volcanic Arc"
Duration-amplitude distribution of volcanic tremor
(American Geophysical Union, 2003)
The duration-amplitude distribution of volcanic tremor was examined in eight volcanoes and one geothermal area. An exponential model, implying a scale-bound source process, is found to be a better fit to the data than a ...
A comparison of different indirect techniques to evaluate volcanic intact rock strength
(Springer, 2009)
The efficiency of different methods that are used to evaluate volcanic intact rock strength is compared that includes Schmidt hammers, point load tests and uniaxial compression tests. The Schmidt hammer records the rebound ...
Mercury fluxes from volcanic and geothermal sources: An update
(The Geological Society of London vol. 410 263 – 285. 2015, 2015-03-01)
We review the state of knowledge on global volcanogenic Hg emissions to the atmosphere and present new data from seven active volcanoes (Poás, Rincón de la Vieja, Turrialba, Aso, Mutnovsky, Gorely and Etna) and two geothermal ...
Geochemistry and fluid circulation at the Tenorio volcanic complex (Costa Rica)
(Geoitalia, 2013-09)
The present work reports the geochemical results gathered from thermal and cold water and discharges, mainly located in the eastern part of the volcanic area of Tenorio
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
