The broad ridge in the distance to the NW is Los Humeros, the easternmost of a series of large silicic volcanic centers with active geothermal systems located north of the axis of the Mexican Volcanic Belt. Eruption of the Xáltipan Ignimbrite about 460,000 years ago resulted in formation of the 15 x 21 km Los Humeros caldera. Recent eruptions at Los Humeros produced extensive basaltic lava flows; hot springs and fumarolic activity continue at Los Humeros, which has a producing geothermal field.
