Rhyolite lava dome growth styles at Chaitén volcano, Chile (2008-2009) : interpretation of thermal imagery

Airborne thermal images of the Chaitén rhyolite lava dome were obtained on three occasions between January 2009 and January 2010. These images were useful for understanding the nature and pace of growth of the newly extruded lava, which formed a complex of lobes and a spine. The images also revealed...
