Cerro Chillahuita (22° 10'S 68° 02W) and Cerro Tocopuri (22° 26'S 67° 58'W) are much smaller bodies (~5 km3) than Chao and are more typical of silicic lava domes the world over. They have almost vertical, scree-covered flanks about 150 m high, a broadly circular basal plan and a flat top and are locally referred to astortas (cakes). Flow folds rib their upper surfaces. These tortas appear to have been the result of single eruptive events which started off explosively - both have small silicic airfall deposits associated with them - and then quickly settled down to passive effusion of the main mass of lava. No evidence of a central source region is present on the surface of the torta.
