埃特纳火山是欧洲最高的一座活火山,它坐落在意大利的西西里岛上,海拔大约有3326米。由于地处亚欧板块和非洲板块的交汇处,埃特纳火山从古至今一直非常活跃。从有文献记载开始已经喷发过200多次了,所以被称为世界上爆发次数最多的火山,它的高度也随着喷发活动不断变化着。有历史记载的第一次喷发是在公元前475年,而最大的一次喷发是在1699年,火山熔岩一直冲到了40公里外的城市——卡塔尼亚,造成了两万人丧生。最近几年,埃特纳火山还在频频喷发,岩浆常常冲毁上山的盘山公路。仅仅在2013年过去的几个月里,埃特纳火山就大大小小喷发了数次。虽然有火山喷发的威胁,这一带却是西西里岛上人口最稠密的地方,因为火山喷吐出的火山灰给这里带来了肥沃的土壤。在海拔900米以下种满了葡萄、橄榄、柑橘、樱桃、柠檬等。不过,到了海 Mount Etna, Europe’s tallest volcano, sits on Sicily, Italy, at an elevation of about 3,326 meters. Due to its location at the confluence of Asia-Europe and Africa plates, Mount Etna has been active since ancient times. Since the literature has been erupted over 200 times, it is known as the volcano in the world with the highest number of eruptions. Its height also varies with the eruption activity. The first recorded eruption was in 475 BC, with the largest eruption in 1699, when volcanic lava rushed to Catania, 40 km away, killing more than 20,000 people. In recent years, Mount Etna is still frequent eruptions, magma often washed up the winding mountain road. Only in the past few months in 2013, Etna volcano erupted large and small several times. Despite the threat of volcanic eruptions, this area is the most densely populated area on Sicily, as volcanic ash sprouts fertile soil here. At 900 meters above sea level planted with grapes, olives, citrus, cherries, lemons and so on. However, to the sea
