At the end of this phase, after roughly one year, the volcano had grown 336 meters (1,100 ft) tall. For the next eight years the volcano would continue erupting, although this was dominated by relatively quiet eruptions of lava that would scorch the surrounding 25 km² (9.7 mi²) of land. The volcano's activity would slowly decline during this period until the last six months of the eruption, during which violent and explosive activity was frequent. In 1952 the eruption ended and Parícutin went quiet, attaining a final height of 424 meters (1,390 ft) from the cornfield where it began. The volcano has been quiet since. Parícutin is believed to be a monogenetic volcano, which means that once it has finished erupting, it will never erupt again. Any new eruptions in a monogenetic volcanic field erupt in a new location.

Paricutin volcano
The volcano began as a fissure in a cornfield owned by a farmer, Dionisio Pulido, on February 20, 1943. Pulido, his wife, and their son all witnessed the initial eruption of ash and stones first-hand as they plowed the field. The volcano grew quickly, reaching five stories tall in just a week, and it could be seen from afar in a month. Much of the volcano's growth occurred during its first year, while it was still in the explosive pyroclastic phase. The nearby villages Paricutín (after which the volcano was named) and San Juan Parangaricutiro were both buried in lava and ash; the residents relocated to vacant land nearby.

Immaginate se, al posto di un campo da coltivare, il contadino avesse costruito la sua casa su quell'appezzamento di terreno.....
