Mount Etna is one of the most active volcanos on earth. The mountain has been in a state of near continuous eruption for half a million years, exploring the ethnic geographical area, reveal a history written in fire, before the eruption it was covered by forest of pine trees. Located in southern Italy, Etna is the highest active volcano in Europe, (16)however it’s height often changes when volcanic material accumulates during eruptions and subsequently collapses. Few volcanoes in the world have the eruption history so thoroughly documented by historical records. Etna’s eruption history dates back as far as 1500 BC, some 200 eruptions have been recorded down through the centuries, but compared with other volcanos, most of its eruptions have so far been fairly light in terms of death and disruption. Only about 100 deaths have been attributed to the volcano, the mountain hasn’t been entirely harmless, however in 1928, it destroyed the town of Macaulay.

(17)Over the centuries, Etna’s lowest slope has been shaped by human hands to take advantage of rich soils for growing grapes, apples and nuts. Local people have also carved out over two hundred caves in the soft rock and use them as everything from secret barrel places to food storage. Large Mammals used to wonder the volcano’s slopes, but today, foxes, wild cats, rabbits and mice are more common, (18)some of those small mammals help to sustain such big birds as golden eagles
