Mount Etna SE Crater Valle del Bove : Mount Etna is one of the most active volcanoes in the world and is in an almost constant state of activity. The fertile volcanic soils support extensive agriculture, with vineyards and orchards spread across the lower slopes of the mountain and the broad Plain of Catania to the south Mount Etna, towering above Catania, Sicily's second largest city, has one of the world's longest documented records of historical volcanism. Historical lava flows cover much of the surface of this massive basaltic stratovolcano, Italy's highest and most voluminous volcano. The Mongibello stratovolcano, truncated by several small calderas, was constructed during the late Pleistocene and Holocene over an older shield volcano. The most prominent morphological feature of Etna is the Valle del Bove, a 5 x 10 km horseshoe-shaped caldera open to the east. It is the tallest active volcano in Europe, currently standing 3,329 metres (10,922 ft) high, though this varies with summit eruptions; the mountain is 21 m (69 ft) lower now than it was in 1981. It is the highest mountain in Italy south of the Alps. Etna covers an area of 1,190 km² (460 sq mi) with a basal circumference of 140 km. 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

Mount Etna SE Crater Valle del Bove : Mount Etna is one of the most active volcanoes in the world and is in an almost constant state of activity. The fertile volcanic soils support extensive agriculture, with vineyards and orchards spread across the lower slopes of the mountain and the broad Plain of Catania to the south Mount Etna, towering above Catania, Sicily's second largest city, has one of the world's longest documented records of historical volcanism. Historical lava flows cover much of the surface of this massive basaltic stratovolcano, Italy's highest and most voluminous volcano. The Mongibello stratovolcano, truncated by several small calderas, was constructed during the late Pleistocene and Holocene over an older shield volcano. The most prominent morphological feature of Etna is the Valle del Bove, a 5 x 10 km horseshoe-shaped caldera open to the east. It is the tallest active volcano in Europe, currently standing 3,329 metres (10,922 ft) high, though this varies with summit eruptions; the mountain is 21 m (69 ft) lower now than it was in 1981. It is the highest mountain in Italy south of the Alps. Etna covers an area of 1,190 km² (460 sq mi) with a basal circumference of 140 km. 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

Mount Etna SE Crater Valle del Bove : Mount Etna is one of the most active volcanoes in the world and is in an almost constant state of activity. The fertile volcanic soils support extensive agriculture, with vineyards and orchards spread across the lower slopes of the mountain and the broad Plain of Catania to the south Mount Etna, towering above Catania, Sicily's second largest city, has one of the world's longest documented records of historical volcanism. Historical lava flows cover much of the surface of this massive basaltic stratovolcano, Italy's highest and most voluminous volcano. The Mongibello stratovolcano, truncated by several small calderas, was constructed during the late Pleistocene and Holocene over an older shield volcano. The most prominent morphological feature of Etna is the Valle del Bove, a 5 x 10 km horseshoe-shaped caldera open to the east. It is the tallest active volcano in Europe, currently standing 3,329 metres (10,922 ft) high, though this varies with summit eruptions; the mountain is 21 m (69 ft) lower now than it was in 1981. It is the highest mountain in Italy south of the Alps. Etna covers an area of 1,190 km² (460 sq mi) with a basal circumference of 140 km. 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

EARTH Indonesia -- 03 Jun 2009 -- Mount Tambora Volcano, Sumbawa Island in Indonesia is featured in this image photographed by a crew member on the International Space Station. On April 10, 1815 the Tambora volcano produced the largest eruption in history. An estimated 150 cubic kilometers of tephra -- exploded rock and ash -- was produced, with ash from the eruption recognized at least 1,300 kilometers away to the northwest. While the April 10 eruption was catastrophic, historical records and geological analysis of eruption deposits indicate that the volcano had been active between 1812 and 1815. Enough ash was input into the atmosphere from the April 10 eruption to reduce incident sunlight on Earth's surface and cause global cooling, resulting in the 1816 "year without a summer". This detailed photograph depicts the summit caldera of the volcano. The huge caldera -- six kilometers in diameter and 1,100 meters deep -- formed when Tambora's estimated 4,000 meter-high peak was removed, and the magma chamber below emptied, during the April 10 eruption. Today the crater floor is occupied by an ephemeral fresh-water lake, recent sedimentary deposits, and minor lava flows and domes emplaced during the 19th and 20th centuries. Layered tephra deposits are visible along the northwestern crater rim. Active fumaroles, or steam vents, are still present within the caldera. In 2004 scientists discovered the remains of a village and two adults buried under approximately three meters of ash in a gully

Mount Etna is an active volcano on the east coast of Sicily, close to Messina and Catania. It is the largest active volcano in Europe, currently standing about 3, 326 m high, though it should be noted that this varies with summit eruptions. It is the highest mountain in Italy south of the Alps. Etna covers an area of 1, 190 km² with a basal circumference of 140 km. This makes it by far the largest of the three active volcanoes in Italy.
