This eight volcanoes in Indonesia are horrendous world

While we break for a while yes hal2 that smells of Korea and we are shifting to our beloved country is being hit by many calamities, ranging from Lapindo mud that has not yet completed n even many small mud semburan2 found again in the township residents, the tsunami in Mentawai, mountain Merapi etc.. Now aq want ngebahas about gunung2 eruption which is still troubling the people of Indonesia, one eruption of Mount Merapi which has claimed hundreds of casualties and even the gatekeeper of the mountain, too, died in a state of prostration ..
There are EIGHT volcano in Indonesia is world famous because of the eruptions. The eight volcanoes in Indonesia, among others: 


1 .. Kelud


Since the 15th century, Mount Kelut has claimed more than 15,000 people. Eruption was in 1586 claiming more than 10,000 inhabitants. A system to divert the lava flow has been made extensively in 1926 and still works to this day after the eruption in 1919 claimed thousands of lives due to cold lava flood swept settlements.
In the 20th century, Mount Kelut recorded eruption in 1901, 1919 (May 1), 1951, 1966, and 1990. In 2007 the mountain was again increased its activity. This pattern brings experts volcano on 15-year cycle for the eruption of this mountain.
 

2. Mount Merapi


Mount Merapi is the youngest in a collection of volcanoes in southern Java. The mountain is located in the subduction zone, where the Indo-Australian plate continues to move down the Eurasian Plate. The eruption in the area lasted from 400,000 years ago, and up to 10,000 years ago the type of eruption is effusive. After that, the eruptions become explosive, with viscous lava domes that give rise to lava.
Small eruptions occur every 2-3 years, and the larger about 10-15 years. Eruptions of Merapi, which impacts, among others, in the years 1006, 1786, 1822, 1872, and 1930. Major eruption in 1006 made the whole middle part of Java island shrouded in gray.
It is estimated, the eruption caused the ancient Mataram kingdom have moved to East Java. The explosion in 1930 destroyed 13 villages and killed 1400 people.



3. Mount Galunggung
Mount Galunggung ever recorded erupted in 1882 (VEI = 5). Early signs of eruption known in July 1822, where the water becomes turbid and muddy Cikunir. Results of the crater showed that the turbid water is hot and sometimes appear in the column of smoke from the crater.
Then on October 8, s.d. October 12, the eruption of reddish sand produces rain very hot, fine ash, hot clouds and lava. Lava flow moving toward the west following the river flows. This explosion killed 4011 people and destroyed 114 villages, with damage to the land to the east and south as far as 40 miles from the mountaintop.

4. Mount Agung
Gunung Agung is located in Bali, last erupted in 1963-64 and is still active, with a large and very deep crater which occasionally smoke and ash. From a distance, the mountain is visible cone, although inside there are large craters.
From the top of the mountain, it is possible to see the summit of Mount Rinjani in Lombok, although both mountains are frequently covered in cloud. On February 18, 1963, local residents heard a loud explosion and saw a cloud rising from the crater of Mount Agung.
On February 24, lava began flowing down the northern slopes of the mountain, eventually traveling seven miles in 20 days. On March 17, the volcano erupted, sending debris 8-10 km into the air and produce a large pyroclastic flow.
This current is much destroying villages, killing around 1500 people. A second eruption on May 16, causing the flow of heat clouds that killed more than 200 other residents.

5. Krakatoa
 
Krakatoa is a volcanic archipelago that are still active and located in the Sunda Strait between Java and Sumatra. This name was ever pinned on a volcanic peak over there (Krakatoa), which vanish because of the eruptions themselves on 26-27 August 1883.
The eruption was so powerful; hot clouds and the resulting tsunami killed about 36,000 people. Until December 26, 2004, this tsunami is that terdahsyat in Indian Ocean region. The sound explosion was heard up in Alice Springs, Australia and the island of Rodrigues near Africa, 4653 miles. Yield is estimated at 30,000 times the atomic bomb that was detonated in Hiroshima and Nagasaki at the end of World War II.
Krakatau eruption caused global climate change. The world was dark for two and a half days due to volcanic ash that covered the atmosphere. The sun was shining dim until next year. Scattering of dust visible in the sky Norway to New York.
The explosion of Krakatoa is actually still less than the eruption of Mount Toba and Tambora in Indonesia, Mount Tanpo in New Zealand and the Mount Katmal in Alaska. But the mountains are erupting deep in the human population is still very little.
Meanwhile, when Krakatoa erupted, the human population is dense enough, science and technology has evolved, the telegraph was invented, and submarine cable has been installed. Thus it can be said that it was information technology is growing and developing rapidly.
Noted that the eruption of Krakatoa was the first major disaster in the world after the invention of the submarine telegraph. Progress is, unfortunately, has not been matched by progress in the field of geology. The geologist was not even able to give an explanation of the eruption

6.
Maninjau
Maninjau caldera formed by volcanic eruptions is estimated to occur around 52,000 years ago. Deposits from the eruption have been found in radial distribution around Maninjau stretches up to 50 miles to the east, 75 km south-east, and west to the coast. Deposits are expected to be distributed over 8,500 km ² and has a volume of 220-250 km ³. This caldera has a length of 20 km and width of 8 km

7. Mount Tambora
 
Volcanic activity culminated in April 1815 when it erupted in a scale of seven on the Volcanic Explosivity Index. The eruption's largest eruption since the Lake Taupo eruption in the year 181.
Eruption was heard up to Sumatra island (more than 2,000 km). Volcanic ash fell in Kalimantan, Sulawesi, Java and Maluku. Volcanic eruption caused the death of up to no less than 71,000 people were killed by 11000-12000 directly as a result of the eruption.
Even some researchers estimate up to 92,000 people were killed, but this figure is questionable because it is based on estimates that are too high. Moreover, these volcanic eruptions cause climate change.
One year later (1816) is often referred to as the Year Without a Summer because of the drastic change of weather North America and Europe due to dust generated from this Tambora eruption. Due to drastic climate change is a lot of crop failure and livestock deaths in the Northern Hemisphere that caused the worst famine in the 19th century.
During an archaeological excavation in 2004, a team of archaeologists found the remains were buried by the eruption of culture in 1815 at a depth of 3 meters in pyroclastic deposits. Artifacts were found in the same position when the eruption occurred in 1815. Because of similar characteristics that is, the findings are often referred to as the Pompeii of the east


 8. Toba supervolcano

Volcanic eruption is the most powerful ever known on planet Earth. And nearly destroyed generations of mankind on planet Earth.
73,000 years ago from Supervolcano eruption in Indonesia nearly destroyed the entire human race. Few survived. And after Tsunami Volcano In Indonesia became active again and threatening humanity.
This eruption can not be compared with anything that has been experienced on earth since the time when humans could walk upright. Compared with the supervolcano Toba, Krakatau even that caused ten thousand deaths in 1883 is just a small burp.
Though Krakatau has explosive power equivalent to 150 megatons of TNT. For comparison: Hiroshima Nuclear Bomb explosions have only 0.015 megatons of explosive power, and verbally then the destruction of 10,000 times weaker than Krakatau.
As has been known to scientists, toba nearly exterminate mankind 73.00 years ago. At that time Neanderthal man inhabited the earth simultaneously with homo sapiens in Europe, as well as Homo erectus and Homo floresiensis in asia. It was very cold in europe, the last ice age is going well where deer, wild horses and giant deer are hunted.
Besides food herbivores, hairy mammoths and rhinos are also often the human food menu at Toba, with a diameter of 90 kilometers on the island now known by the name Sumatera.Meledak in the true sense.
Along with the huge tsunami waves, there are 2800 cubic kilometers of ash released, which spread throughout the atmosphere of our earth. Which may have reduced the number of human population to only about 5000 to 10,000 men only.
Manusia Sebenarnya today comes from a few thousand human survivors of a super volcano Toba eruption 73,000 years ago. Therefore Volcanoes in Indonesia responsible for the almost extinction of mankind.
And from 60 to 70 volcanoes which can ditemuai in the area (Indonesia) now. Some of them became active again in a few months or several weeks after the earthquake in dasarlaut in december 2004.
Although Toba is still far away and safe sleeping under a great ocean which bears the same name in North Sumatra. many people are afraid if one day the active volcano in the Gutters is located 300 kilometers south of the Toba eruption, could awaken a sleeping giant.
