Four still clearly visible craters, a huge caldera, and an original height estimated at 3,000 meters. A volcano the size of Etna capable of shaping the orography of the entire Roman and Pontine plain.
The Lazio volcano, on which Roman castles rest for centuries, is a giant that is far from extinct. For experts, who have kept it under close surveillance for years and not only because of its proximity to Rome, it is a fully active volcano, although without eruptions for millennia. In fact, it is estimated that the life cycle of the volcano is 38-40 thousand years and that the last significant eruptions are 35 thousand years old.
Here in the last two days, precisely from 2:00 p.m. on Friday to 1:36 p.m. on Saturday, there have been 15 earthquakes: the strongest, of magnitude 3.0, was the opening one. Then another 6 arrived with a magnitude greater than 2.0: not really caresses but, for the moment, shocks that highlight what is the typical seismicity of these areas.
But apart from the earthquakes to testify the vitality of a volcano that has gas emissions in the three lakes (those of Castel Gandolfo and Nemi and the dry one of Vallericcia) and in the cone of Monte Cavo some of the largest and most recent craters. and soil survey. According to INGV experts, this is a sign of a gradual filling of the magma chamber. We still cannot know what and when will happen. But whoever regards the Lazio Volcano as a battered old giant is not exactly right. Rather.
