- DESCRIPTION
-
- With a total
volume of 600 km cubic, an height of 3,348 metres on sea level,
Etna is the highest active volcano in Europe. The slopes of Etna
accommodate more than 250 adventive cones that were once active
craters opened at various altitudes. Certainly among the most
famous craters we have the "Monti Rossi", that opened themselves
in 1669 at the altitude of 800 m. above sea-level and the
"Silvestri", that opened themselves in 1892 at about 2000 m
above sea-level. On the top of Etna we observe four craters with
open duct, called: Bocca Nuova (New Mouth), Voragine (Abyss),
South-East Crater, North-East Crater. Each of them has a middle
diameter of 250 meters.
-
The east part of the volcano
accommodates the Bove Valley, a caldera which developed about
10,000 years ago, whose dimensions are about 10 km x 7 km, and
that is about 900 meters deep.
The Bove Valley developed after an impressive collapse of the
caldera. Today is still possible to notice the geological
structure distinctly, that overbearingly dominates the landscape
of the East side of Etna.
