Etna

[et-nuh]
Etna or Aetna, volcano, 10,958 ft (3,340 m) high, on the east coast of Sicily, S Italy. It is the highest active volcano in Europe. The shape and height of its central cone have often been changed by eruptions. There are more than 260 lesser craters on the slopes, formed by lateral eruptions. The southeastern slope is cut by a deep (2,000-4,000-ft/610-1219-m), precipitous cleft, the Valle del Bove. The first known eruption occurred in 475 B.C. and was described by Pindar and Aeschylus. Of the numerous later eruptions, often accompanied by earthquakes, those of 1169 and 1669 were the most destructive; the most recent major eruption occurred in 1992.

The wide base of Mt. Etna, c.93 mi (150 km) in circumference, is encircled by a railroad. The fertile lower slopes are densely populated agricultural areas. Up to 1,600 ft (488 m) the vegetation is subtropical, yielding citrus fruit, bananas, and figs; between 1,600 and 4,300 ft (488-1,311 m) is a temperate zone, with vineyards and various fruit trees; from there to c.7,000 ft (2,130 m) are chestnut, birch, and pine woods; above, there is a desolate waste of lava and ashes. Near the top there is snow most of the year. There is an observatory at 9,650 ft (2,941 m). A motor road from Nicolosi, NW of Catania, to the 6,170-ft (1,881-m) level was completed in 1935.

Active volcano, eastern coast of Sicily, Italy. The highest active volcano in Europe, its elevation is more than 10,000 ft (3,200 m); its base has a circumference of about 93 mi (150 km). Mount Etna has repeatedly erupted over the centuries, most violently in 1669, when the lava flow destroyed villages on the lower slope and submerged part of the town of Catania. Activity was almost continuous in the decade following 1971, and in 1983 an eruption that lasted four months prompted authorities to explode dynamite in an attempt to divert lava flows. Mount Etna also experienced violent eruptions in 2001–02, prompting the Italian government to declare a state of emergency.
