20 years of active deformation on volcano caldera: Joint analysis of InSAR and AInSAR techniques
(Elsevier Science, 2013-08)
InSAR (interferometric synthetic aperture radar) techniques are applied to investigate last two decades of surface deformation of the Cerro Blanco/Robledo Caldera (CBRC). The objective is the identification of deforming ...
Magmatic gas percolation through the old lava dome of El Misti volcano
(Springer Berlin HeidelbergDE, 2017-05)
The proximity of the major city of Arequipa to El Misti has focused attention on the hazards posed by the active volcano. Since its last major eruption in the fifteenth century, El Misti has experienced a series of modest ...
Advances in scientific understanding of the Central Volcanic Zone of the Andes: a review of contributing factors
(Springer, 2022-02-12)
The Central Volcanic Zone of the Andes (CVZA) has been the focus of volcanological research for decades, becoming a very important site to understand a number of volcanic processes. Despite most of the research in the CVZA ...
Preliminary geochemical study of thermal waters at the Puracé volcano system (South Western Colombia): An approximation for geothermal exploration
(Universidad Industrial de Santander, 2018-01-01)
The Puracé Volcano is located in the Cauca department, SW of Colombia, along the Coconucos volcanic chain. This volcano is an interesting target for geothermal exploration, because it is a young caldera-type volcano, with ...
Carbon isotope systematics of Turrialba volcano, Costa Rica, using a portable cavity ring-down spectrometer
(AGU Publications, 2017-07-27)
Over the past two decades, activity at Turrialba volcano, Costa Rica, has shifted from hydrothermal to increasingly magmatic in character, with enhanced degassing and eruption potential. We have conducted a survey of the ...
Localization with multicomponent seismic array
(Institute of Electrical and Electronics Engineers, 2011)
Seismo-volcano source localization is essential to improve our understanding of volcano systems. The lack of clear seismic wave phases prohibits the use of classical location methods. Seismic antennas composed of one-component ...
Turmoil at Turrialba Volcano (Costa Rica): Degassing and eruptive processes inferred from high-frequency gas monitoring
(Wiley, 2016-08-28)
Eruptive activity at Turrialba Volcano (Costa Rica) has escalated significantly since 2014, causing airport and school closures in the capital city of San José. Whether or not new magma is involved in the current unrest ...
