Paricutin Volcano, Mexico

Around three-quarters of a century ago, Paricutin was said to have suddenly emerged from a farmer's cornfield.

5. Description and History

The Paricutin is a unique volcano in Mexico known for its sudden appearance in 1943 from out of a cornfield owned by a Mexican farmer named Dionisio Pulido. This scoria-cone volcano is located close to the city of Uruapan in the Michoacán state of the country. The then active Paricutin volcano offered scientists a great opportunity to study the life cycle of a volcano, and the volcanic site became a central point of scientific research. By 1952, the volcano had developed a 424-meter-high cone and had also damaged vast tracts of nearby land, spanning an area of around 233 square kilometers. Though only three people were thought to have been killed, damage to property was huge, and two towns had to be emptied completely to ensure the safety of the residents of the region. Currently, however, the Paricutin volcano is dormant and a popular tourist attraction in the country.

4. Scientific Research

The Paricutin Volcano has acted as a treasure trove for the scientific community. It has helped scientists uncover many unknown facts related to volcanism. The volcano offered modern science the rare opportunity to document the entire life cycle of a volcano. Right after its first eruption, scientific teams, the most prominent being those of the Smithsonian and the Mexican government, visited the site. Detailed photographs, maps, and field studies revealed immense knowledge regarding the scoria cone formation. Within a span of five years from 1943 to 1948, around 50 scientific publications related to the volcano were produced and more continue to be generated even today.

3. Uniqueness

The Paricutin is a unique volcano in many respects. First, it is most famous for its sudden appearance from the corn field. Also, it completed part of its lifespan within a short span of time, allowing scientists an in-depth view of the life cycle of a volcano. It is also the most notable volcano among the scoria cone type volcanoes of the world. It is the youngest volcano among the 1,400 volcanoes in the Michoacán-Guanajuato volcanic field.

2. Geology and Environmental Role

The Paricutin Volcano is part of the Trans-Mexican Volcanic Belt, a series of volcanoes and cinder cones that have shaped the topography of the country for thousands of years. The volcanic activities of these volcanoes have generated mountains, rock deposits, and fertile volcanic soil. The lava, ash, and smoke produced by the Paricutin Volcano destroyed large areas of surrounding land, displacing the people inhabiting such regions. It also polluted the air around it with huge volumes of toxic fumes during the eruption events.

1. Threats and Conservation

Though the Paricutin Volcano is currently designated as extinct by most geologists, some signs and symptoms of past volcanism linger on to the present day. Since the volcano is still hot, rainwater that seeps in escapes in the form of steam from its crater. The ground beneath the volcano is also highly unstable, and several series of earthquakes have occurred in the area in and around the volcano. In 1997 and 2006, there were reports of earthquakes in the Paricutin area. In 1995, black steam and rumbling of the volcano were reported.
