"Recently the Etna Volcano , has returned to erupt . Was made public on the website of the National Institute of Geophysics and Volcanology, this volcano threw a small lava flow from the crater and reached an area of one kilometer wide. "
Recall that the major eruption produced by this volcano was the March 11, 1669 lasting several months of activity and producing several strong earthquakes . ( 1)
Etna is an active volcano on the east coast of Sicily, between the provinces of Messina and Catania . It has around 3,322 meters. It is the tallest active volcano with the Eurasian plate , the second referring to the European policy after the Teide and the highest mountain in Italy south of the Alps.

Volcanism began occurring 300,000 years ago to the west of the current summit , before activity moved towards the present center 170,000 years ago. Eruptions that time began to build the main volcanic edifice , forming a stratovolcano in alternating eruptive and effusive eruptions . Eruptions of Etna are not all the same .
Some occur at the summit, where there are currently four distinct craters : the Northeast Crater , the Voragine , the Bocca Nuova , and the Southeast Crater .
