A newborn volcano in Rome?

Two weeks ago in Italy, next to the Fiumichino International Airport near Rome, the geyser scared. It is not yet obvious that this is not a breakthrough of the gas pipeline (which is unlikely), but the Bul-Bulk is serious. Right on the side of the road.

In this regard, I would like to remind you of the frosty - a volcano that grew up on a corn field. On February 20, 1943, smoke went from the ground on a corn field in Mexico. The local peasants first tried to plug the hole with stones, which the author heard from Jim Lura, who wrote a whole book on this volcano (Russian Wikipedia, however, writes that they used a hole in the ground to dispose of garbage), but literally in a day, the rarrow grew by several tens of meters, then hundreds of meters, and a year later, lava flowed out of it. After that, almost continuously erupting for nine years, Porcutin did not reach a little to a height of three kilometers.
