Abstract Here we report on the first assessment of volatile fluxes from hyperacid crater lake hosted within summit Copahue, a very active volcano Argentina‐Chile border. Our observations were performed using variety in situ and remote sensing techniques during field campaigns March 2013, when an fumarole field, 2014, acidic volcanic covered field. In latter campaign, found that 566 to 1373 t d −1 SO 2 being emitted plume appeared largely invisible. This, combined with our derived bulk...
Synthetic Aperture Radar (SAR) Differential Interferometry (DInSAR) and its extensions to manage time series are nowadays well-known mastered techniques perform among others land-motion monitoring. We present here a fully automated monitoring service based on DInSAR Multidimensional Small Baseline Subset (MSBAS) methods. The processing chain named "InSAR Mass Toolbox for multidimensional Time series" (MasTer) is demonstrated with the peculiar case of Laguna del Maule Domuyo volcanoes, which...
Abstract The integration of inverse thermal history modeling new geochronological data with structural analyses from the western flank Domuyo volcano (∼36°30′S) allows us to propose a detailed cooling key region in Southern Andes. area is located northwestern part Chos Malal fold‐and‐thrust belt back‐arc Despite extensive geological investigations this region, details about early stages Andean deformation remain poorly understood. present study focuses on interpretation and U‐Pb, fission...
Abstract The crater lake and associated hydrothermal features of Copahue volcano have been studied intensively over the last 20 years (1995–2015). geochemical isotopic compositions waters provide insights into processes occurring in volcanic–hydrothermal system, thermal springs. Variations temperature chemical composition reveal fundamental changes system that precede accompany magmatic phreatic eruptive events at Copahue. A conceptual model summit was developed involving intrusion slivers...
Planchón-Peteroa volcano started a renewed eruptive period between January 2010 and July 2011. This was characterized by the occurrence of 4 explosive phases, dominated low-intensity phreatic activity, which produced almost permanent gas/steam columns (200-800 m height over active crater). Those presented frequently scarce ash, were interrupted explosions that ash 1,000-3,000 in more intense periods. Eruptive plumes transported several directions (NW, N, NE, E SE), but than half time plume...
