Encyclopædia Britannica, Inc.The eruption of Paricutín lasted for nine years and produced one of the world's youngest volcanoes. Ash and lava began spewing from an open field in 1943 in Michoacán state, Mexico, and buried nearby settlements and farmland and displaced local people. The result was a new cinder cone volcano. This video, produced in the 1970s, includes footage taken during the eruption.
