Ground deformation between 2002 and 2013 from inSAR observations

Ground deformation is one of the main geophysical methods for volcano monitoring. Surface deformation patterns can provide important insights into the structure, plumbing system, and state of restless volcanoes. Copahue volcano is one of the most active eruptive centers in Argentina, and a major ris...

Historic eruptive activity involved low intensity phreatic and phreatomagmatic events in 1992, 1995 and 2000.Anew eruptive cycle is ongoing since June 2012, with several phreatic explosions and one phreatomagmatic-magmatic eruption on December 22nd, 2012.
