| This slide shows the cinder cone soon after its birth in 1943 in a Mexican cornfield. During its brief nine-year lifespan (1943-1952), it built a 410-meter-high cone with extensive lava fields around the base of the cone. | Most of the 2 km3 of eruptive products (ash, cinders, and lava) were produced in the first few years. Cinder cones such as this one are commonly formed by one eruption. Each subsequent eruption in the same area forms its own cinder cone. Photo credit: K. Segerstrom, U.S. Geological Survey . |
