Evolution of a dynamic paleo-hydrothermal system at Mangatete, Taupo Volcanic Zone, New Zealand
(Elsevier Science, 2014-06)
Recent quarrying and active faulting at Mangatete, Taupo Volcanic Zone (TVZ), New Zealand, illuminate a rare spatial and temporal window on a dynamic Late Quaternary geothermal system. Detailed geological mapping, stratigraphic ...
Space- and ground-based measurements of sulphur dioxide emissions from Turrialba Volcano (Costa Rica)
(Springer Verlag, 2012-06-21)
Remotely sensed measurements of sulphur dioxide (SO2) emitted by Turrialba Volcano (Costa Rica) are reported for the period September 2009–January 2011. Thesemeasurements were obtained using images from Advanced Spaceborne ...
Evolution of the eruption of the Ubinas Volcano (Peru) 2006
(Instituto Geológico, Minero y Metalúrgico - INGEMMETPE, 2006)
[Abstract] The gases emanations of Ubinas volcano (16º 22' S, 70º 54' O; 5672 altitude. ), was increased lightly during July of 2005, after these was almost void since 2001. The emitted gases came up to 200 - 300 m of ...
Geophysical, geochemical and geodetical signals of reawakening at Turrialba volcano (Costa Rica) after almost 150 years of quiescence
(Elsevier, 2010-11)
Turrialba is a basaltic–andesitic stratovolcano (3340 masl), in the Cordillera Volcánica Central in Costa Rica. After the last eruption (1864–1866), volcanic manifestations were limited to weak fumarolic discharge (continuous ...
Deformation and seismicity near Sabancaya volcano, southern Peru, from 2002 to 2015
(American Geophysical Union, 2015-03-19)
We use interferometric synthetic aperture radar (InSAR) and local seismic data to investigate the cause of earthquake sequences near Sabancaya volcano in southern Peru from 2002 to 2014, with a particular focus on events ...
The crater lake of Copahue volcano (Argentina): Geochemical and thermal changes between 1995 and 2015
(Geological Society Publications House, 2016-12)
The crater lake and associated hydrothermal features of Copahue volcano have been studied intensively over the last 20 years (1995-2015). The geochemical and isotopic compositions of the waters provide insights into the ...
Deformation of Copahue volcano: Inversion of InSAR data using a genetic algorithm
(Elsevier Science, 2011-04)
The Copahue volcano is one of the most active volcanoes in Argentina with eruptions having been reported as recently as 1992, 1995 and 2000. A deformation analysis using the Differential Synthetic Aperture Radar technique ...
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 ...
