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 ...
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 ...
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) ...

The Guayabo Caldera, a 14 km diameter volcanic depression with Miravalles volcano rising 2028 ma.s.l. in the norte astern side of so called, formed by repeated eruption sand multiple collapses which dis membered earlier ...
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 ...
