Paricutin
Paricutin is probably Mexico's most famous volcano but it is a small
one. Paricutin is but one of >1000 vents in the Michoacan-Guanajuato
monogenetic field. The reason Paricutin is famous is because people were
able to observe it forming from its very beginning. It is the famous
"volcano that grew out of a cornfield". It was not really a very dangerous
eruption for people, but it was quite destructive of their agricultural
lands, livestock, and way of life. The eruption lasted from 1943 until
1952, produced a large cinder and ash cone, and covered an area about 8
kilometers by 8 kilometers with slow-moving lava flows. A very
comprehensive book that covers just about everything known about Paricutin,
was recently written by Jim Luhr and Tom Simkin of the Smithsonian
Institution.
