Etna, the most active volcano on the European continent, located on the Italian island of Sicily, has erupted after registering 250 mini-eruptions in the last ten days.

The National Institute of Geophysics and Volcanology (INGV) published a report last Friday in which it explained that between November 19 and December 1 250 “Strombolian” type eruptions had been recorded and a “rhythmic” frequency, intermittent.

This activity is “completely normal” for an “open conduit” volcano like Etna, but the INGV experts highlight in the document that the eruptions occur at times “so regular” that they seem “marked like a Swiss watch.”

The series analyzed It began with a “paroxysm” on November 12 but on the 19th the volcano once again showed “signs of life.”

However, during the following days Etna began to record eruptions “at a particular rhythm”with periods of between 10 and 15 minutes of agitated “Strombolian” activity, that is, violent explosions separated by periods of calm.

While as of November 24, The eruptions occurred on average every 70 minutes.

The INGV “assumed” as “plausible” that the brief and spectacular eruptions of the great Sicilian volcanic cone during this period they are due “to the dynamics of magma increase” towards the surface.
