Ash from these eruptions has been found as far away as south of Rome's border, 800 km (497 mi) to the north.Thousands of years ago, the eastern flank of the mountain experienced a catastrophic collapse, generating an enormous landslide in an event similar to that seen in the 1980 eruption of Mount St. The landslide left a large depression in the side of the volcano, known as 'Valle del Bove' (Valley of the Ox).
It is also known as Mungibeddu in Sicilian and Mongibello or Montebello in Italian (the Italian word literally means "beautiful mountain").
According to another hypothesis, the term Mongibello comes from the Latin Mulciber (qui ignem mulcet, "who placates the fire"), one of the Latin names of the Roman god Vulcan.
five distinct craters — the Northeast Crater, the Voragine, the Bocca Nuova, and the Southeast Crater Complex (2).
Other eruptions occur on the flanks, which have more than 300 vents ranging in size from small holes in the ground to large craters hundreds of metres across.
Research published in 2006 suggested this occurred around 8000 years ago, and caused a huge tsunami, which left its mark in several places in the eastern Mediterranean.
It may have been the reason the settlement of Atlit Yam (Israel), now below sea level, was suddenly abandoned around that time.It is the highest active volcano in Europe outside the Caucasus. This makes it by far the largest of the three active volcanoes in Italy, being about two and a half times the height of the next largest, Mount Vesuvius.Only Mount Teide in Tenerife (owned by Spain) surpasses it in the whole of the European–North-African region west of the Black Sea.Summit eruptions can be highly explosive and spectacular, but rarely threaten the inhabited areas around the volcano.In contrast, flank eruptions can occur down to a few hundred metres altitude, close to or even well within the inhabited areas.Mediaevalist Roger Sherman Loomis quotes passages from the works of Gervase of Tilbury and Caesarius of Heisterbach ( dating from the late twelfth century ) featuring accounts of Arthur's returning of a lost horse which had strayed into his subterranean kingdom beneath Etna.
