section::::history of volcanic eruptions.:geological history.





























volcanic activity first took place at etna about 500,000 years ago, with eruptions occurring beneath the sea off the ancient coastline of sicily. about 300,000 years ago, volcanism began occurring to the southwest of the summit (centre top of the volcano), then activity moved towards the present centre 170,000 years ago. eruptions at this time built up the first major volcanic edifice, forming a stratovolcano in alternating explosive and effusive eruptions. the growth of the mountain was occasionally interrupted by major eruptions, leading to the collapse of the summit to form calderas.

section::::geopolitical boundaries.





























the borders of ten municipalities (adrano, biancavilla, belpasso, bronte (from two sides), castiglione di sicilia, maletto, nicolosi, randazzo, sant'alfio, zafferana etnea) meet on the summit of mount etna, making this point one of elevenfold complexity, and the most complicated geopolitical multi-point anywhere north of the south pole.
