The Process of Mountain Erupts

Definition volcanic eruption, caused by magma sediment in the bowels of the earth, driven out by the high-pressure gas. From eruptions like these volcanoes are formed.
Eruptions of ash and rock that brought loud burst with a radius as far as 18 miles or more, while the lava could flood the area as far as 90 km radius. Volcanic eruptions can cause casualties and great property or thousands of miles away and even biases affect the climate of the earth is round. Results in the form of volcanic eruptions:

  1. Volcanic gases
  2. Lava Flow and Heat Sand and Stone
  3. Lava
  4. Ash eruption
  5. Heat clouds (pyroclastic)
Volcanic gases are gases released during volcanic eruptions that released include carbon monoxide (CO), Carbondioksida (CO2), Hydrogen Sulfide (H2S), sulfur dioxide (SO2) and nitrogen (NO2) which is harmful to humans.
Lava is a high-temperature liquid magma that flows to the surface through a volcanic crater. Thin lava flows away from its source is able to follow the river or the valley while the thick lava flows not far from its source.
Lahar is a danger to the public one of the tingla on the slopes of the volcano. Lahar is a flash flood on the slopes of the mountain that consists of a mixture of volcanic-sized lump of clay till. Known as the eruption and lava lava rain. Lava eruptions occurred when the volcano that has erupted crater lake, so the lake is hot water mixed with the eruption of material, while the rain lava eruptions occur due to material mixing with rain water around the peak.
Volcanic ash is a very fine material. Because wind impact can be felt hundreds of kilometers away. The impact of the ash respiratory problems, vision difficulties, pollution clean water sources, cause electrical storms, disrupt work and motor vehicle engines, damaging the roof, damaging fields, damaging infrastructure body.
Hot clouds can form pyroclastic flows, pyroclastic pyroclastic blast and fallout. Hot clouds of material flow is a major eruption cloud is hot, flowing down and eventually settle in and around the river of the valley. Blowing hot cloud is a cloud of small eruptions of hot material, blown by the wind speed reaches 90 km / h. Dropping hot cloud is a cloud of hot material large and small eruption that was brought up by the force of the eruption. Large material would fall around the peak, while the fine would fall in the tens, hundreds or even thousands of miles from the summit because of the influence of wind gusts. Hot clouds can cause severe burns to exposed body parts such as head, arms, neck or legs and also to not cause shortness of breathe.
Cause teradinya Mount erupts
  1. Increased volcanic seismicity
  2. Increased temperatures crater
  3. Increase in magnetic and electric waves, until the occurrence of deformation on the body mounts.
  4. Earth plates jostle each other and magma in the earth's crust is urging and encouraging the earth's surface and trigger the geological activity, volcanic, and tectonic.
  5. Due to the very high pressure, the magma pushes out (eruption) of the earth's surface as lava.
The process of mountain erupts
In some eruptions, huge clouds up into the mountain, and the river of lava flows on the flanks of the volcano. In another eruption, ash and red-hot coals of fire burst out of the top of the mountain, and chunks of the hot stones thrown high into the air. Most small eruptions have enormous power, so large that it can divide the mountain
Basically, a volcano is formed from magma, the molten rock deep within the earth. Magma is formed due to the heat in the Earth's interior temperature. At a certain depth, the temperature is very high heat so as to melt the rocks in the earth. When the molten rock, gas dihasilkanlah then mixed with magma. Most of the magma formed at depths of 60 to 160 km below the earth's surface. Others are formed at depths of 24 to 48 km
Magma containing gas, gradually rising to the surface because of its mass is lighter than solid rocks around him. When magma rises, the magma melts the rocks nearby, forming a large cabin at a depth of about 3 km from the surface. Magma chamber is what is shed (reservoir) where volcanic eruptions originating materials
Magma containing gas in magma cabin is in a condition under heavy pressure rocks that surround it. This pressure causes the magma erupts or melt conduit (channel) on the rocks brittle or cracked. Magma moves out through the channel leading to the surface. When magma close to the surface, the gas content in it regardless. Gas and magma burst together and form a hole called the main hole (central vent). Most of the magma and other volcanic material then gush out through this hole. After bursts of stops, crater (crater) that resemble bowls typically form on the top of the volcano. While there are major holes in the bottom of the crater

History of Kuta Beach


Kuta is a familiar name in the world of tourism in Bali. Who does not know the beauty of Kuta Beach Bali? The beach is always crowded every day of foreign and domestic travelers to enjoy the crashing waves of the famous.

Coconut trees will be seen along the sand beach as far as the eye could mememandang to the north that was stopped by the Ngurah Rai airport runway in the far west. Additionally sunset Kuta became the number one spot in Bali, with a view of the spectacular sunsets each day.At night, live Kuta nightlife. Western influences appear to make a lot of discos, dance clubs, and pubs. There are many restaurants serving Indonesian food, and various other international foods. As if this were not enough, there are also various Balinese dance performances are staged in Kuta every night. One of the best Kecak Dance performances can be found in Kuta. 
  
History of Kuta BeachFormerly, this place is a fishing village of Bali, but as time went on, this became a famous tourist area in Bali. It may be said, Kuta is now a gathering place for travelers from all over the world, because almost all the tourists who visit the island of Bali, definitely do not forget to also stop by to Kuta.Historically almost all the beaches in Bali formerly a turtle landings. Along with the time travel, only a few places that went to lay eggs, and one of which is Kuta Beach. Kuta Beach is not only visited by tourists but also visited by turtles to lay their eggs. It is very surprising to see the condition of Kuta Beach is packed with a lot of the hotel. Turtles were landed on Kuta Beach is timeless turtles (Lepidochelys olivacea).Attractions: Bali's Kuta Beach is a tourist attraction complete, the merger between historical and Tourism beaches make this attraction Kuta Beach is one tourist attraction is a mainstay in the province of Bali.

Prambanan Temple



Prambanan temple is the temple built by Sanjaya Dynasty kings in the ninth century. Invention of writing the name of the temple raises Pikatan opinion that this temple was built by Rakai Pikatan who later settled by the Rakai Balitung based on the stone inscription dated 856 AD "inscription Siwargrarha" as a political manifest to confirm his position as king in 856 AD besar.Prasasti Siwargrarha issued by Rakai pikatan unknown origin, are kept in the National Museum Jakarta.This inscription is beginning to attract attention after J.G. De Casparis successfully describe and discuss it. According Casparis there are 3 important things in the inscription, namely: His language is the oldest example dates to inscriptions written in ancient Javanese poetry; contents contain materials or historical events are very important from the mid-abas to IX M; It poses a description a detailed description of a "cluster of temples", something unique in Javanese epigraphy kuna.Dari interesting description above is a description of historical events and the cluster of temple construction. Historical event in question is a battle between Balaputeradewa of Sailendra family against family Rakai Pikatan of Sanjaya. Balaputeradewa defeated and fled to Sumatra. Consolidation of the royal family Rakai Pikatan it then becomes the beginning of a new period of development that needs to be formalized by a large group of temples.The description of the cluster of temple as it is called in the inscription Siwargrarha can be compared to the temple complex of Prambanan, the cluster of temple which was built around its center is lined walls and surrounded by a row of ancillary temples arranged bersap Prambanan.Disebutkan only found in the temple as well as ancillary temples in the shape and size.Another interesting point is 2 Apit temples, each one near the northern entrance of the cluster and selatan.Keterangan temple is located near the river are reminiscent of the cluster of temple Prambanan with Opak river to the west and if from the distance between the river and the cluster of temple Prambanan Opak and the possible diversion of the river flow deflection occurs between the villages of Klurak and punch. Thus, it seems that the description contained in the inscription on the cluster of temple Siwargrarha is more suited to the state of Prambanan temple.The transfer to the central Javanese kingdom of Mataram East terawatnya not result in the temples in the Prambanan, the condition is getting worse by the earthquake and the eruption of Mount Merapi several times which makes the Prambanan temple collapsed and left debris scattered stones. Prambanan temple is known back when a Dutchman named CALons visited Java in 1733 and reported on the ruins of the temple is overgrown shrubs.First attempt to save the temples of Prambanan performed by Ijzerman in 1885 by cleaning the cubicles of the ruins of stone temples. In 1902 building work began, led by Van Erp to the Shiva temple, Vishnu temple and Brahma temple. Attention to Prambanan temple continues to grow. In 1933 successfully developed experimental Brahma and Vishnu temples. After experiencing various barriers refurbishment completed by Indonesia, dated December 23, 1953 Shiva temple was completely refurbished and officially declared by the President Dr selasai. Ir. Sukarno.Prambanan temple restoration in the region continue to be implemented, including the restoration of the temple of Brahma and Vishnu temples. Brahma temple restoration began in 1977 and was completed and inaugurated by Prof Dr. Haryati Soebandio dated March 23, 1987. Vishnu temple restoration began in 1982 completed and officially opened by President Soeharto on 27 April 1991. Subsequent restoration activities conducted on the three temples in front of the temple of Shiva, Vishnu and Brahma temple besarta 4 color and 4 corner temples.

Lake Toba



Lake Toba is a volcanic lake with a length of 100 kilometers and 30 kilometers wide, located in North Sumatra Province, Indonesia. This lake is the largest lake in Indonesia and Southeast Asia. In the middle of this lake there is a volcanic island called the island. Lake Toba has long been an important tourist destination in North Sumatra and Nias Bukit Lawang, attract domestic and foreign tourists. Lake Toba is expected explosion occurred at about 73000-75000 years ago and an eruption (super volcano) the most recent. Bill Rose and Craig Chesner of Michigan Technological University estimate that the volcanic materials spewed out of the mountain as much as 2800 km ³, with 800 km ³ of rock overlies and 2,000 km ³ of volcanic ash which is expected in the wind to the west for 2 weeks. Volcanic dust in the wind has spread to half the earth, from China to South Africa. The explosion occurred during a week and throw the dust up to 10 km above sea level. This incident caused mass death and the extinction of some species also followed. According to some DNA evidence, this eruption also reduced the number of people to about 60% of the total human population of the earth at that time, which is about 60 million people. The eruption also caused the ice age, although experts are still debating. After the eruption, the caldera formed which was then filled with water and became what is now known as Lake Toba. Upward pressure by magma that has not come out cause the appearance of the island. International multidisciplinary research team, led by Dr. Michael Petraglia, said in a press conference in Oxford, the United States that has found a new archaeological site that is quite spectacular by geologists in the south and north India. At the site revealed how people survive, before and after volcanic eruptions (Supervolcano) in Toba 74,000 years ago, and evidence of life below the ash heap of Mount Toba. Though the source of the eruption within 3,000 miles, from the distribution of ashes. For seven years, experts from Oxford University is researching ecosystem project in India, to look for evidence of life and the lives they left behind equipment in a barren desert. Area with an area of ​​thousands of hectares of this was just the savanna (grassland). While the animal bones were scattered. The team concluded that a quite large area was covered with dust from this ancient volcanic eruptions. The spread of volcanic dust was very wide, are found almost all over the world. Supervolcano eruption comes from an ancient, namely Mount Toba. Allegations leading to Mount Toba, because it found evidence of molecular forms of volcanic ash in the same 2100 period. Since the caldera crater, now a lake Toba in Indonesia, up to 3000 miles, from the source of the eruption. In fact, surprisingly enough, it turns out that the spread of dust caught up to the North Pole. This is reminiscent of the experts, how powerful the super volcano Toba eruption at the time.

Mountains were snow-covered







Snow-covered mountains happened in the cold season to be precise after the area or this mountain was closed snow.
