Understanding and forecasting phreatic eruptions driven by magmatic degassing
(Springer Nature, 2018-05-18)
This paper examines phreatic eruptions which are driven by inputs of magma and magmatic gas. We synthesize data from several significant phreatic systems, including two in Costa Rica (Turrialba and Poás) which are currently ...
Eruptive activity of Peteroa Volcano for period 2010-2011, Southern Volcanic Zone, Chile
(SERNAGEOMIN, 2016)
Planchon-Peteroa volcano started a renewed eruptive period between January 2010 and July 2011. This eruptive period was characterized by the occurrence of 4 explosive eruptive phases, dominated by low-intensity phreatic ...
Characterization of the ashes from the 2014-2015 Turrialba Volcano eruptions by means of scanning electron microscopy and energy dispersive x-ray spectroscopy
(2016)
The Turrialba Volcano is a stratovolcano located approximately 35 km northwest from San José, Costa Rica’s capital city. Since October 29, 2014, until at least late 2015, a series of eruptions has represented ...

Spatial shifts in fumarolic degassing at Poás volcano: Phreatic Activity in the Ultra Acid Crater Lake versus Subaerial Degassing
(IAVCEI Commission on Hazards and Risk, 2011-09-11)
Summary of the presentation Spatial shifts in fumarolic degassing at Poás volcano: Phreatic Activity in the Ultra Acid Crater Lake versus Subaerial Degassing
Magmatic volatiles in ash leachates and environmental impact assessment of the 29-30 October 2014 phreatic eruptions of Turrialba Volcano, Costa Rica
(The International Union of Geodesy and Geophysics (IUGG), 2015)
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 ...
On data reduction methods for volcanic tremor characterization: the 2012 eruption of Copahue volcano, Southern Andes
(Terra Scientific Publishing, 2020-12)
Improving the ability to detect and characterize long-duration volcanic tremor is crucial to understand the long-term dynamics and unrest of volcanic systems. We have applied data reduction methods (permutation entropy and ...
