The silence of the seven active volcanoes in the outbreak of the global threat of death
1, Iceland's Laki Laki
Iceland's Laki Laki
Iceland southern volcanic cracks and mountains, close to Iceland's largest ice sheet vatnajokull (Vatnajokull) Southwest.
Laki fissure eruption of volcano mountain is in the process of formation of unique characteristics of terrain is significantly called Laki craters (Lakagigar). The crack for northeast-southwest direction, Laki mountain make it stop for nearly equal parts. Laki mountain altitude 818 meters (2,684 ft), up to 200 meters in the vicinity (650 feet). Laki Hill did not fully disclose their cracks. On the hillside between several cracks and only very little out of small amounts of lava crater.Volcanic eruption in 1783, 8 June, and July 29, just south of Laki fissure in Shanxi province.
On the same day, cracks start to the North-East of the volcano eruption, almost entirely in the cracks of the half. Eruption lasted until early February 1784, was considered to be the largest ever Earth lava eruptions. General agreement that the magma eruption about 12.3 cubic kilometres (2.95 cubic miles), cover about $ 565 square kilometres (220 sq. miles). A large number of volcanic gases causing most of the European continent, smog or even spread to Syria, Siberia and Altai Mountains in the western part of North Africa. Release of large amounts of sulphur gas got in the way of Iceland's growing crops and vegetation, resulting in the death of most of the livestock. Smog caused by famine finally result in Iceland 1/5 people lost their lives.2, Gera, Wyeth volcano KILAUEA
Kilauea volcano
Kilauea Volcano (KILAUEA) is located in the southeastern United States Hawaii island.
Kilauea volcano, is the world's active force strong active volcanoes, still often eruption. The mountain has a large Caldera, 4027 m in diameter, depth of 130 meters, which contains many of the crater. The crater is like a big pot, pot and cover with a kettle (crater). The caldera of the southwest corner of a busy with glowing lava of the volcano, with a diameter of about 1000 meters, about 400 m deep, where lava, sometimes up to the formation of spray, fountain, sometimes overflow crater, shaped like a waterfall, the local indigenous people call it Harry friction, which means the eternal flame.Here was the persistence of a world's largest lava Lake, an area of 500 to 10 000 square meters, red woven hot magma usually have more than ten meters deep, the cry of the Lake, in the roll like a furnace boiling liquid.
The edge of the Lake, often produces dark red orange peel, they stacked up like a bundle of rope, orange peel and sometimes cracked after dumping into the incandescent magma. The Lake is also a few metres from time to time appear high lava fountains, splash with colorful sparks. All these scary scene, called the wonders of nature.1960 Kilauea volcano big eruptions, lava flow from above Pentium catharsis, pour into the sea, on the beach has produced a new about 2 square kilometres of land.
29 July 2002, rolling magma from Kilauea volcano spewed, flows into the sea, water, fire and blend to form a spectacular sight. In 2002, 17 August, the volcano red magma rolls out into the sea, like a magma Dragon.20 years, the Kilauea volcano continued emission of a large number of magma was formed in South of Hawaii Islands several new black sand beach and the area of the island.
3. Mauna Volcano (Mauna Loa)
Maunaloa, vol.
In Hawaii Volcanoes National Park (1916 building), the world's largest one solitary mountain.
Altitude 4,169 meters (13,678 ft). Its dome Hill long 120 km (75 miles) wide, 103 km (64 miles), lava flows through 5,120 km2 (2,000 sq miles). Crater Mo library arbeo sveio (Mokuaweoweo) an area of 10 km2 (4 sq miles), deep 152sim; 183 m (600 ft 500sim;). In winter the top often snow-covered.1832 year average every three and a half years once erupted, most of the ejecta of the restriction in Mo library arbeo sveio crater, while the rest along the North-East or South-West side of the fracture zone.
In 1935 the outbreak, the US military aircraft had threatened to Hilo (Hilo) city of magma flow diameter bombs. June 1950, for a period of 23 days the vast magma from a 21 km (13 miles) southwest side crack down, destroyed a small village. 1975, 1984 peak occurred in large eruptions.Nbsp; maunaloa Volcano (Mauna Loa) is an active volcano,
Over the past 200 years, eruptions over 35 times. So far, the top of the hill there are also several pot-shaped crater and width up to 2700 m large caldera. November 1959, Mauna volcano erupted again, then boiling lava risked bubble from one up to a kilometer and a half of gap Jet out duration up to a month, the magmatic maximum height more than New York's Empire State building. March 1984, Mauna volcano erupted again, rare stockholmers, attracting tourists from around the world.4 the Vesuvius, Italy
Vesuvius
Vesuvius (Vesuvius)-the world's most famous volcano, located in one of Campania plain of Naples Bay.
In 1944 eruption formed. 2,000,000 more people living in the region and the Vesuvius slopes downward. Along the coast of Naples Bay industrial town in the northern foothills of distribution, as small agricultural center.After several centuries still occur after a series of earthquakes in the last 6 months and a gradual increase in strength, 1631, Dec. 16, taking a major eruption.
Hillside many villages were destroyed and about 3,000 deaths; lava flows to the sea, the sky is dark for a few days. 1631 years after volcanic eruption profile changes, volcanic activity continued. Volcanic activity can be observed in two stages: stationary and eruptive period. Rest period closed, eruptive period volcano crater opened almost continuously.Foothills around the vineyards and orchards, this estate wine called 「introduction Christ tears wine 」 (Lacrima Christi); ancient Pompeii there on the-jar 「introduction Vesuvio 」 (Vesuvinum).
Mountain height around the oak and chestnut hardwood forest. The northern slope of the hillside along the forest has been long soma to the peak. The chestnut trees on the West side length, altitude of 600 meters (2,000 ft) above are all over the cytisus plants of rugged plateau, a.d. 79 years the big eruption of the volcano has been filled in. Further to the above, the large cone of slopes and the inside of the cable-Masan almost barren hillside, in the Volcano still period is a green grass plants.Vesuvius in 1.2 years from time to time, the likes of eruption, the volcano is always a rising smoke rings, radiates sufficient to ignite a piece of paper.
Located at the foot of the orchards and vineyards, and on the slopes of the volcano is desolate and sinister. 20th century Vesuvius has changed 6 times a massive eruption.The most famous of the Vesuvius eruption occurred in a 79-year, Hector Herculaneum and Pompeii two town were destroyed.
Volcanic spray out black smoke, hot stones of volcanic ash raining down, toxic gases into the air. Pompeii only a quarter of the population survived, the others are not buried by volcanic ash, smoke is being, or were asphyxiated collapsed building pressure die.Saint Helens, vol. 5, (Mount St Helen 's, US)
Saint Helens, vol.
Located in Northwest Washington State, United States, the Cascade Mountains in the North.
2950 meters above sea level (1983). Hibernate 123 years after in 1980 and 27 March suddenly resurrected, 18 may, the most violent eruption plumes to the 2 million meters of height, volcano ash with air diffusion-4000 kilometres away, at distance of 800 km of the volcano has 1.8 cm thick. Volcano near river blocked, traffic diversion, many roads were buried. Lava flow caused by forest fires, surrounded by dozens of kilometers extinct. Because of the large number of mountain and snow melt, forming the Rapids, coupled with increased air flow of large amounts of water vapor in the air to condense, storm disaster to scour the formation of volcanic ash and mud torrent pours down from the hills have seriously undermined the farmland, forests along the way and all facilities. Volcanic eruptions, nearby terrain change significantly, the original volcanic cone top landslide, forming a long 3 km, width 1.5 km, depth of 125 m of new crater. This volcanic eruption caused 60 deaths, 390 square kilometers of land into a barren land, great losses, is the history of the United States, and is also on the Earth since the 20th century the largest volcanic eruptions. In recent years, it has its activities.nbsp;
In the 1980 eruption, Saint Helens, vol. shape shapely, peak is covered with snow, much like Japan's Mt. Fuji, Mt. Fuji, known as the United States, attracting many tourists. The eruption in 1980 marked the volcano from 1857 sleep wake up again after 123 years. Then after the unexpected change.
As a result of volcanic eruptions, for a longer period of time prior to the earthquake and volcanic eruption of steam, emergency work properly, and make better forecasts, St Helen's volcanic outbreak not caused more casualties.
Saint Helen, vol. dormant long than active phase, St. Helen's eruption experience tells us that don't looks like dead volcano lightly.6, Monte Etna volcano Etna

Etna volcano
Italy, Sicily, on the East coast of active volcanoes.
Its name comes from the Greek Atine (aithn, means 「introduction I burned 」). The highest volcano in Europe. Altitude 3,200 meters (10,000 ft) above, and other active volcanoes, its height is different each time change, such as 1865 20 century to 52 metres (170 ft). 1,600 square kilometers (600 sq miles). Base perimeter of about 150 kilometres (93 miles).nbsp;
The highest volcano in Europe. The most violent eruptions continued 1669, 4 months, down lava about 7.8 billion cubic meters. Undermine the very serious, Catania, near the city of 2 million people lost their lives. 1981: March 17, the eruption was over recent decades the most violent once buried dozens of hectares of forest and many vineyards, hundreds of houses were destroyed. Hillside vegetation distribution: minimum belt, full of fruit tree plantations; intermediate belt, beech, oak and pine trees; the highest band, sparse scattered shrubs and algae. The mountains have Memorial Monuments of Roman Emperor mountaineering.
7, Ecuador of Sangay National Park Sangay
Ecuador in Sangay
Sangay National Park is located in Central Ecuador Morona mdash; San Diego, Chimborazo and Tungurahua province.
Located near the equator, with an area of 2720 sq km. The Park is a world famous world active duration, the longest active volcanoes mdash mdash;; Sangay volcano. Altitude 5410 m Sangay volcano snowy, Highlands, from the peak to the foothills of nearly 4000 m of altitude before in this form the unique landscape of Ecuador. Because the entire Park is located near the equator, the Sun, the height above sea level around is also different, thus showing a different ecological spectacle, with many rare plants and animals.Rainforest growing up 30-40 meters of trees, tall and straight.
Volcanic ash stacked into a very fertile ground to make a very lush plants here. In addition to hard woody plants are Moss, Lichen, combs with round Corm and shaped like leaves of the Compositae.
