Parícutin (or Volcán de Parícutin, also accented Paricutín) is a dormant scoria-cone volcano located in the Mexican state of Michoacán, near the city of Uruapan and about 322 km west of Mexico City. The volcano surged suddenly from the cornfield of local farmer Dionisio Pulido in 1943, attracting both popular and scientific attention. This eruption presented the first occasion for modern science to document the full life cycle of an eruption of this type. During the 9-year life span of Parícutin, scientists sketched and mapped it, took samples as well as thousands of photographs of this volcano. By 1952, the volcano left a 424 meter high cone and significantly damaged a 233 km2 area with the ejection of stone, ash and lava.
