The ground is still hot atop the crater of Paricutin 鈥� the first volcano of its kind to have its full life cycle documented by modern science when it erupted 80 years ago.

The surrounding vista in western Mexico encompasses pine-clad peaks of older volcanoes, green avocado orchards and a church tower just peeking above where lava buried it decades ago.

Volcanoes are still being born around the globe and scientists believe another will form in the volcanic field spanning across this region, they just don鈥檛 know when.

That鈥檚 why about a hundred geologists, volcanologists and seismologists visited Paricutin last week to mark the anniversary, share experiences and talk about how to prevent disaster.

Paricutin鈥檚 birth and nine-year eruption were a cornerstone in the study of the relatively small kind of volcano that erupts only once, said Stavros Meletlidis, a Greek researcher at Spain鈥檚 National Geographic Institute.

The world鈥檚 most famous volcanos already were thousands of years old when they threw up their catastrophic eruptions: Mount Vesuvius in Italy which buried Pompeii in 79 A.D.; Mount Tambora in Indonesia which killed tens of thousands in 1815.

To witness the origin of a new one is rare. It can start with a peculiar noise.

A deep sound is what Meletlidis remembers hearing in September 2021 before seeing the column of gas signaling the emergence of a volcano on Spain鈥檚 La Palma island. That was the most recent new volcano to form in a populated area. He and his team had been monitoring it for four years. The eruption was the 鈥渓ast breath鈥� of a process that had begun 10,000 years earlier in the center of the Earth, he said.

Guadalupe Ruiz, 92, remembers hearing such a noise on Feb. 20, 1943, after weeks of small tremors in the western part of Mexico鈥檚 Michoacan state.

Then, it felt 鈥渓ike water rising underground,鈥� and, finally in the following days, it was 鈥渓ike a thunderclap or a kick from a horse鈥� as Paricutin鈥檚 cone began to form and rocks fell all around, she said.

Ruiz was then a 12-year-old girl in San Juan Parangaricutiro, Mexico, where she and her neighbors thought it was the end of the world. A farmer came running with his hat covered in ash saying that his corn field had opened up.

鈥淭hey told us it was hell,鈥� said Ruiz, her long grey hair in braids.

A team of geologists from the U.S. Department of the Interior and Mexican scientists visited the site 20 times between 1943 and 1945 and summarized the eruption in a report more than a decade later. On that initial day, there was a mild explosion followed by 鈥渁 small eruptive column carrying dust, and some hot stones arose from this new vent,鈥� the report said.

鈥淎fter about 8 hours of such activity the new volcano began to roar and to hurl out quantities of incandescent bombs with great force,鈥� it said. Within six days, it reached a height of 167 meters (548 feet), the report said.

The adults cried, Ruiz recalled.

Curious children tried to get close 鈥渢o see the lava move, little by little,鈥� said Abel Aguilar, motioning like waves with his hand. He was 5 at the time.

The landscape went from a 鈥渟mall and beautiful volcanic monster鈥� to a 鈥渄esolate and wiped out world鈥� of dying trees and homes filling with ash, wrote Mexican journalist Jos茅 Revueltas, who visited 40 days after the eruption for the Popular newspaper.

When geologists arrived, they consoled the community because they were able to explain what happened and 鈥� importantly 鈥� provide work, Ruiz said.

鈥淢y dad took the Americans on horseback to see where the fire was coming out and where the little mountain was forming,鈥� she said.

Paricutin鈥檚 lava eventually covered seven square miles (18.5 square kilometers). Its slow advance allowed residents of the surrounding communities to relocate to land donated by the government.

Nobody was killed.

Unlike earthquakes, volcanoes sometimes give people time to react.

In the years leading up to the 2021 eruption on La Palma, clusters of tremors had increased in frequency a week before the eruption. Also, deformities on the surface suggested magma was pushing up. Two days before the eruption there was a strong smell of sulfur in springs monitored by scientists.

The Paricutin volcano is within a volcanic belt that crosses Mexico.

Tremors in recent years including a burst late last year have raised fears that another volcano could appear, said Luis Fernando Lucatero, the local civil defense coordinator. Scientists later confirmed last year鈥檚 quakes were superficial with no magma rising toward the surface.

The National Autonomous University of Mexico鈥檚 Geophysics Institute has installed seismographs in key locations to monitor the volcanic field, and trained local leaders to detect other signals.

Denis Legrand, one of the volcanologists on the project, said more equipment and personnel are needed because with the current number of stations some tremors could go unnoticed until it is too late to react.

A year and a half after the Paricutin eruption began, residents of the largest area town of San Juan left in a procession behind the image of their patron saint and rebuilt their town and church elsewhere. The old town was later buried in 50 feet (15 meters) of lava.

While the volcano today draws visitors who bring an important source of income, the buried church is a reminder of what the earth unleashed.

鈥淎 volcano give life. It sometimes destroys too,鈥� Meletlidis said.
