Volcanic eruption in Chile: Change analysis
Volcanic eruption in Chile: Change analysis
Change analysis based on data from the radar satellite Sentinel-1, obtained before (20/02/2015) and shortly after (04/03/2015) the Villarrica in Chile erupted on 3 March 2015. Blue: increase in radar backscattering caused by the melting of snow and ice; cyan: strong increase in radar backscattering due to the accumulation of volcanic material; magenta: reduction in radar backscattering caused by an accumulation of ash. DLR produced the analysis during activation of the International Charter 'Space and Major Disasters'.
