火山原 · Mexico · 3860m

Parícutin, the volcano that grew in a cornfield in 1943, is a well-known feature of the Michoacán-Guanajuato volcanic field. The huge field contains over 1,400 vents covering a wide area across the Michoacán and Guanajuato states. Scoria cones are the predominant volcanic landform, and lava domes, maars, tuff rings, and lava flows are also present. Parícutin is seen here from the NE with the Nueva Juatita flank vent in the foreground, the main source of lava during the last five years of the eruption.

地質学的概要

The widespread Michoacán-Guanajuato volcanic field contains over 1,400 vents, including the historically active cinder cones of Parícutin and Jorullo, covering a 200 x 250 km wide area of Michoacán and Guanajuato states in west-central México. Cinder cones are the predominant volcanic form, but small shield volcanoes, lava domes, maars and tuff rings (many in the Valle de Santiago area), and coneless lava flows are also present. The volcanoes with shield-type morphologies are mostly Pleistocene in age, although the Michoacán-Guanajuato centers have higher slope angles and smaller basal diameters. Jorullo, which was constructed in the 18th century, and Parícutin, which grew above a former cornfield during 1943-52, are the two best known volcanic features scattered throughout the field.

Wikipedia の要約

英語版の要約

The Michoacán–Guanajuato volcanic field is located in the Michoacán and Guanajuato states of central Mexico. It is a volcanic field that takes the form of a large cinder cone field, with numerous shield volcanoes and maars. Pico de Tancítaro is the highest peak.
