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