Journal ArticleDOI
Network for Observation of Volcanic and Atmospheric Change (NOVAC)—A global network for volcanic gas monitoring: Network layout and instrument description
Bo Galle,Mattias Erik Johansson,Claudia Rivera,Yan Zhang,Manne Kihlman,Christoph Kern,Thomas Lehmann,Ulrich Platt,Santiago Arellano,Santiago Arellano,Silvana Hidalgo +10 more
TL;DR: The Network for Observation of Volcanic and Atmospheric Change (NOVAC) project as mentioned in this paper uses a scanning miniaturized differential optical absorption spectroscopy (Mini-DOAS) instrument to measure volcanic gas emissions at active volcanoes.
Journal ArticleDOI
Petrological analysis of the pre-eruptive magmatic process prior to the 2006 explosive eruptions at Tungurahua volcano (Ecuador)
Pablo Samaniego,Jean-Luc Le Pennec,Jean-Luc Le Pennec,Claude Robin,Claude Robin,Silvana Hidalgo +5 more
TL;DR: The case of Tungurahua volcano has been studied in this article, where thermobarometric data point to magmatic temperatures ranging from 950 to 1015°C and pressures in the range of 200 to 250 MPa, which corresponds to 7.5-9.5 km below the summit.
Journal ArticleDOI
Adakitic magmas in the Ecuadorian Volcanic Front: Petrogenesis of the Iliniza Volcanic Complex (Ecuador)
Silvana Hidalgo,Silvana Hidalgo,Michel Monzier,Hervé Martin,Gilles Chazot,Jean-Philippe Eissen,J. Cotten +6 more
TL;DR: The Iliniza Volcanic Complex (IVC) is a poorly known volcanic complex located 60 kin SSW of Quito in the Western Cordillera of Ecuador as mentioned in this paper.
Journal ArticleDOI
Across-arc versus along-arc Sr-Nd-Pb isotope variations in the Ecuadorian volcanic arc
Marie-Anne Ancellin,Pablo Samaniego,Ivan Vlastélic,François Nauret,Adbelmouhcine Gannoun,Silvana Hidalgo +5 more
TL;DR: In this paper, the authors evaluate how these processes vary along the Ecuadorian arc in response to small-scale changes in the age of the subducted plate, subduction angle, and continental crustal basement.
Journal ArticleDOI
The Medieval Climate Anomaly and the Little Ice Age in the eastern Ecuadorian Andes
M.-P. Ledru,Vincent Jomelli,Pablo Samaniego,Mathias Vuille,Silvana Hidalgo,M. Herrera,C. Ceron +6 more
TL;DR: In this paper, an upslope convective index based on the ratio between cloud transported pollen from the Andean forest to the bog and Poaceae pollen frequencies, related to the edaphic moisture of the p'aramo (P), was defined.
