Paricutin, Mexico is a volcano that grew from a farmerís cornfield. Farmers had been experiencing earthquakes prior to the eruption. The eruption was a spectacular event that created a initial cinder cone that grow to 36 m (1,100 feet) to a volcano with extensive lava flows.

The eruption began in 1943 and ended in 1952. Pyroclastic fragments of spheroidal bombs, lapilli, glassy cinders, and ash were the main components of the cinder cone.
