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 ...
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 ...
