Los Azufres is one of several silicic volcanic complexes with active geothermal near the center of the Trans-Mexican Volcanic Belt. Located about 200 km NW of Mexico City, Los Azufres consists of an 18 x 20 km early Pleistocene caldera that was later partially filled by resurgent dacite to rhyolite lava domes. This view shows the Agua Fria fault and thermal features looking NE from Cerro Pizcuaro.
