Falso Azufre

The Falso Azufre volcanic complex is a 15-km-long, E-W trending group of overlapping craters, lava domes, and composite cones extending from Chile into Argentina. The western portion includes the high point and principal edifice of the complex, Cerro Falso Azufre, and consists of overlapping craters that produced dominantly pyroclastic products. The eastern portion, located wholly in Argentina, contains two small composite cones and two lava domes that appear to represent the most recent activity of the complex and may be of Holocene age (de Silva, 2007 pers. comm.).

The snow-capped Falso Azufre volcanic complex rises along the Chile-Argentina border near Laguna Verde (upper left) in this NASA Space Shuttle image (with north to the upper left). The western portion includes Cerro Falso Azure, the high point of the complex, with prominent snow-covered craters. The eastern portion (toward the lower right) is located wholly in Argentina and contains small composite cones and lava domes (with lesser amounts of snow in this image) that appear to represent the most recent activity of the complex.
