Mapping and measuring lava volumes from 2002 to 2009 at El Reventador Volcano, Ecuador, from field measurements and satellite remote sensing

M. Fernanda Naranjo, Susanna K. Ebmeier, Silvia Vallejo, Patricio Ramón, Patricia Mothes, Juliet Biggs, Francisco Herrera
2016 Journal of Applied Volcanology  
Measurements of lava thickness made from a small set of Synthetic Aperture Radar (SAR) interferograms allowed the retrieval of the shape of the compound lava flow field and show that in 2009 it was subsiding  ...  Estimates of lava volume, and thus effusion rate, are critical for assessing volcanic hazard and are a priority for volcano observatories with responsibility for monitoring.  ...  Acknowledgements We would like to acknowledge the efforts and support of Instituto Geofisico scientists and staff who have worked on monitoring El Reventador since 2002.  ...

Active Tectonics and Earthquake Geology Along the Pallatanga Fault, Central Andes of Ecuador

Stéphane Baize, Laurence Audin, Alexandra Alvarado, Hervé Jomard, Mathilde Bablon, Johann Champenois, Pedro Espin, Pablo Samaniego, Xavier Quidelleur, Jean-Luc Le Pennec
2020 Frontiers in Earth Science  
Based on new geological data and the analysis of a 4 m spatial resolution Digital Elevation Model (DEM), we provide a detailed and comprehensive description of section of the Chingual Cosanga Pallatanga  ...  The detailed analysis of the available DEM allowed mapping a series of lineaments at the regional scale and along the entire fault system.  ...  They determined the surface deformation rate between 2003 and 2009, using the Persistent Scatters InSAR (PSI) technique to perform time series analysis of ground deformation.  ...

2018 Remote Sensing  
Then we use these models to evaluate changes of static stress on the surrounding faults and volcanoes and produce maps of potentially activated faults and volcanoes.  ...  Using Sentinel-1 Interferometric Synthetic Aperture Radar (InSAR) and continuous GPS data, we measure the coseismic ground deformation and estimate the distribution of slip over the fault rupture.  ...  ) project (ECHO/SUB/2015/718679/Prev02) and by the Spanish Ministry of Economy and Competitiveness under INTERGEOSIMA (CGL2013-47412) and ACTIVESTEP (CGL2017-83931-C3), QUAKESTEP (1-P) + 3GEO(2-P) + GEOACTIVA  ...

Thermal, Deformation, and Degassing Remote Sensing Time Series (CE 2000-2017) at the 47 most Active Volcanoes in Latin America: Implications for Volcanic Systems

K. Reath, M. Pritchard, M. Poland, F. Delgado, S. Carn, D. Coppola, B. Andrews, S. K. Ebmeier, E. Rumpf, S. Henderson, S. Baker, P. Lundgren (+13 others)
2019 Journal of Geophysical Research - Solid Earth  
By quantifying the amount of degassing, thermal output, and deformation measured at each of these volcanoes, we test the classification of these volcanoes as open or closed volcanic systems.  ...  We use satellite observations of degassing, thermal anomalies, and surface deformation spanning 17 years at 47 of the most active volcanoes in Latin America and compare these data sets to ground-based  ...  We acknowledge the CEOS volcano pilot project and the space agencies that provided data: Agenzia Spaziale Italiana (ASI) for CSK data, the German Space Agency for TSX/TDX data, the Canadian Space Agency  ...

Laboratory Modelling of Volcano Plumbing Systems: A Review [chapter]

Olivier Galland, Eoghan Holohan, Benjamin van Wyk de Vries, Steffi Burchardt
2015 Advances in Volcanology  
Section 2 examines the fundamental concepts of dimensional analysis and similarity in laboratory modelling.  ...  We outline how laboratory models have yielded insights into the main geometric and mechanical controls on the development of each part of the volcanic  ...  , such as Tromen Volcano, Northern Patagonia, Argentina (Marques and Cobbold 2006; Galland et al. 2007b; Llambías et al. 2011) , Guagua Pichincha Volcano, Ecuador (Legrand et al. 2002) , and El Reventador  ...
