bali

Bali is an Indonesian island located at 8°25′23″S, 115°14′55″, the westernmost of the Lesser Sunda Islands, lying between Java to the west and Lombok to the east. It is one of the country's 33 provinces with the provincial capital at Denpasar towards the south of the island. The island is home to the vast majority of Indonesia's small Hindu minority. It is also the largest tourist destination in the country and is renowned for its highly developed arts, including dance, sculpture, painting, leather, metalworking and music.

Bali has been inhabited since early prehistoric times firstly by descendants of a prehistoric race who migrated through mainland Asia to the Indonesian archipelago, thought to have first settled in Bali around 3000 BC.[citation needed] Stone tools dating from this time have been found near the village of Cekik in the island's west.
Balinese culture was strongly influenced by Indian, and particularly Sanskrit, culture, in a process beginning around the 1st century AD. The name Balidwipa has been discovered from various inscriptions, including the Blanjong charter issued by Sri Kesari Warmadewa in 913 AD and mentioning Walidwipa. It was during this time that the complex irrigation system subak was developed to grow rice. Some religious and cultural traditions still in existence today can be traced back to this period. The Hindu Majapahit Empire (1293–1520 AD) on eastern Java founded a Balinese colony in 1343. When the empire declined, there was an exodus of intellectuals, artists, priests and musicians from Java to Bali in the 15th century.
The First European contact with Bali is thought to have been when Dutch explorer Cornelis de Houtman arrived in 1597, though a Portuguese ship had foundered off the Bukit Peninsula as early as 1585.[citation needed] Dutch rule over Bali came later, was more aggressively fought for, and they were never ultimately able to establish themselves as they had in other parts of Indonesia such as Java and Maluku.
In the 1840s, a presence in Bali was established, first in the island's north, by playing various distrustful Balinese realms against each other. The Dutch mounted large naval and ground assaults first against the Sanur region and then Denpasar. The Balinese were hopelessly overwhelmed in number and armament, but rather than face the humiliation of surrender, they mounted a final defensive but suicidal assault, or puputan. Despite Dutch demands for surrender, an estimated 4,000 Balinese marched to their death against the invaders. Afterwards the Dutch governors were able to exercise little influence over the island, and local control over religion and culture generally remained intact.
Japan occupied Bali during World War II during which time a Balinese military officer, Gusti Ngurah Rai, formed a Balinese 'freedom army'. Following Japan's Pacific surrender in August 1945, the Dutch promptly returned to Indonesia, including Bali, immediately to reinstate their pre-war colonial administration. This was resisted by the Balinese rebels now using Japanese weapons.
On 20 November 1946, the Battle of Marga was fought in Tabanan in central Bali. Colonel I Gusti Ngurah Rai, 29 years old, finally rallied his forces in east Bali at Marga Rana, where they made a suicide attack on the heavily armed Dutch. The Balinese battalion was entirely wiped out, breaking the last thread of Balinese military resistance. In 1946 the Dutch constituted Bali as one of the 13 administrative districts of the newly-proclaimed Republic of East Indonesia, a rival state to the Republic of Indonesia which was proclaimed and headed by Sukarno and Hatta. Bali was included in the ‘’Republic of the United States of Indonesia’’ when the Netherlands recognised Indonesian independence on Dec. 29, 1949. In 1950 Bali officially renounced the Dutch union and legally became a province within the Republic of Indonesia.
The 1963 eruption of Mount Agung killed thousands, created economic havoc and forced many displaced Balinese to be transmigrated to other parts of Indonesia.
In 1965, after a failed coup d'etat in Jakarta against the national government of Indonesia, Bali, along with other regions of Indonesia most notably Java, was the scene of widespread killings of (often falsely-accused) members and sympathizers of the Communist Party of Indonesia (PKI) by right-wing General Soeharto-sponsored militias. Possibly more than 100,000 Balinese were killed although the exact numbers are unknown to date and the events remain legally undisclosed.[2] Many unmarked but well known mass graves of victims are located around the island[citation needed].
On October 12, 2002, a car bomb attack in the tourist resort of Kuta killed 202 people, largely foreign tourists and injured a further 209. Further bombings occurred three years later in Kuta and nearby Jimbaran Bay.

Bali is famous for many forms of art, including painting, sculpture, woodcarving, handcrafts, and performing arts. Balinese gamelan music is highly developed and varied. The dances portray stories from Hindu epics such as the Ramayana. Famous Balinese dances include pendet, legong, baris, topeng, barong, and kecak (the monkey dance).
National education programs, mass media and tourism continue to change Balinese culture. Immigration from other parts of Indonesia, especially Java, is changing the ethnic composition of Bali's population.
The Hindu new year, Nyepi, is celebrated in the spring by a day of silence. On this day everyone stays at home and tourists are encouraged to remain in their hotels. On the preceding day large, colorful sculptures of ogoh-ogoh monsters are paraded and finally burned in the evening to drive away evil spirits. Other festivals throughout the year are specified by the Balinese pawukon calendrical system.

Prambanan

Prambanan is the largest Hindu temple compound in Indonesia, located in Central Java, approximately 18 km east of Yogyakarta.[1]
It was built around 850 CE by either Rakai Pikatan, king of the second Mataram dynasty, or Balitung Maha Sambu, during the Sanjaya Dynasty. Not long after its construction, the temple was abandoned and began to deteriorate. Reconstruction of the compound began in 1918. The main building was completed in around 1953. Much of the original stonework, which has often been stolen and reused at remote construction sites. A temple will only be rebuilt if at least 75% of the original stones are available, and therefore only the foundation walls of most of the smaller shrines are now visible and with no plans for reconstruction.
Today, the temple is a UNESCO World Heritage Site and is one of the largest Hindu temples in south-east Asia. It is characterised by its tall and pointed architecture, typical of Hindu temple architecture, and by the 47m high central building inside a large complex of individual temples.
The temple was damaged during the earthquake in Java in 2006. Early photos suggested that although the complex appears to be structurally intact, damage is significant, with large pieces of debris, including carvings, scattered over the ground. The temple has been closed to the public until damage can be fully assessed. The head of Yogyakarta Archaeological Conservation Agency stated that: "it will take months to identify the precise damage".[2] However, some weeks later in 2006 the site re-opened for visitors. The immediate surroundings of the Hindu temples remain off-limits for safety reason.

Borobudur

Borobudur is a ninth century Buddhist Mahayana monument in Central Java, Indonesia. The monument comprises six square platforms topped by three circular platforms, and is decorated with 2,672 relief panels and 504 Buddha statues.[1] A main dome is located at the center of the top platform, and is surrounded by seventy-two Buddha statues seated inside perforated stupa.
The monument is both a shrine to the Lord Buddha and a place for Buddhist pilgrimage. The journey for pilgrims begins at the base of the monument and follows a path circumambulating the monument while ascending to the top through the three levels of Buddhist cosmology, namely, Kamadhatu (the world of desire); Rupadhatu (the world of forms); and Arupadhatu (the world of formless). During the journey, the monument guides the pilgrims through a system of stairways and corridors with 1,460 narrative relief panels on the wall and the balustrades.
Evidence suggests Borobudur was abandoned following the fourteenth century decline of Buddhist and Hindu kingdoms in Java, and the Javanese conversion to Islam.[2] It was rediscovered in 1814 by Sir Thomas Raffles, the British ruler of Java. Borobudur has since been preserved through several restorations. The largest restoration project was undertaken between 1975 and 1982 by the Indonesian government and UNESCO, following which the monument was listed as a UNESCO World Heritage Site.[3] Borobudur is still used for pilgrimage, and once a year Buddhists in Indonesia celebrate Vesak at the monument. It is Indonesia's single most visited tourist attraction.[

Mount Semeru

Semeru also Gunung Semeru - is the tallest mountain on the island of Java and one of its most active volcanoes. Known also as Mahameru (Great Mountain), it is very steep and rises abruptly above the coastal plains of eastern Java. Maars containing crater lakes have formed along a line through the summit. Semeru lies at the south end of the Tengger Volcanic Complex.
Semeru's eruptive history is extensive. Since 1818, at least 55 eruptions have been recorded (10 of which resulted in fatalities) consisting of both lava flows and pyroclastic flows. Moderate explosive eruptions (VEI 2-3) have also been recorded with some regularity.
Semeru has been in a state of near-constant eruption from 1967 to the present. At times, small eruptions happen every 10 minutes or so.
Semeru is regularly climbed by tourists, usually starting from the village of Rano Pani to the north, but though non-technical it can be dangerous. Soe Hok Gie, an Indonesian political activist of the 1960s died in 1969 from inhaling poisonous gas while hiking on Mount Semeru.

Mount Merbabu

From Wikipedia, the free encyclopedia

Mount Merbabu (Indonesian: Gunung Merbabu) is a dormant stratovolcano in Central Java province on the Indonesian island of Java. Loosely translated, Gunung Merbabu could mean 'Mountain of Ash' from the Indonesian word babu. The active volcano Mount Merapi is directly adjacent on its south-east side, while the city of Salatiga is located on its northern foothills. A 1,500m high broad saddle lies between Merbabu and Merapi, the site of the village of Selo and highly fertile farming land.
There are two peaks; Syarif (3,119 m) and Kenteng Songo (3,145 m). Three U-shaped radial valleys extend from the Kenteng Songo summit in northwesterly, northeastly and southeastly directions.


Two known moderate eruptions occurred in 1560 and 1797 and were rated 2: Explosive, on the Volcanic Explosivity Index. An unconfirmed eruption may have occurred in 1570 [1]. Geologically recent eruptions originated from a North Northwest-South Southeast fissure system that cut across the summit and fed the large-volume lava flows from Kopeng and Kajor craters on the northern and southern flanks, respectively.
Merbabu can be climbed from several routes originating from the town of Kopeng on the north east sideside, and also from Selo on the southern side. A climb from Kopeng to Kenteng Songo takes between 8 and 10 hours.

Monitoring of merapi mountain

Mount Merapi is the site of a very active volcano monitoring program. Seismic monitoring began in 1924, with some of the volcano monitoring stations lasting until the present. The Babadan (north west location), Selo (in the saddle between Merbabu and Merapi), and Plawangan monitoring stations have been updated with equipment over the decades since establishment. During the 1950s and early 1960s some of the stations were starved of equipment and funds, but after the 1970s considerable improvement occurred with the supply of new equipment. Some of the pre-1930 observation posts were destroyed by the 1930 eruption, and newer posts were re-located. Similarly after the 1994 eruption, the Plawangan post and equipment were moved into Kaliurang as a response to the threat of danger to the Volcanological personnel at the higher point.
The eruption of 1930 was found to have been preceded by a large earthquake swarm. The network of 8 seismographs currently around the volcano allow volcanologists to accurately pinpoint the hypocentres of tremors and quakes.
A zone in which no quakes originate is found about 1.5 km below the summit, and is thought to be the location of the magma reservoir which feeds the eruptions.
Other measurements taken on the volcano include magnetic measurements and tilt measurements. Small changes in the local magnetic field have been found to coincide with eruptions, and tilt measurements reveal the inflation of the volcano caused when the magma chambers beneath it is filling up.
Lahars (a type of mudflow of pyroclastic material and water) are an important hazard on the mountain, and are caused by rain remobilizing pyroclastic flow deposits. Lahars can be detected seismically, as they cause a high-frequency seismic signal. Observations have found that about 50 mm of rain per hour is the threshold above which lahars are often generated.

2006 eruption of merapi

In April 2006, increased seismicity at more regular intervals and a detected bulge in the volcano's cone indicated that fresh eruptions were imminent. Authorities put the volcano's neighboring villages on high alert and local residents prepared for a likely evacuation. On April 19 smoke from the crater reached a height of 400 metres, compared to 75 metres the previous day. On April 23, after nine surface tremors and some 156 multifaced quakes signalled movements of magma, some 600 elderly and infant residents of the slopes were evacuated.[3]
By early May, active lava flows had begun. On May 11, with lava flow beginning to be constant, some 17,000 people were ordered to be evacuated from the area[4] and on May 13, Indonesian authorities raised the alert status to the highest level, ordering the immediate evacuation of all residents on the mountain.[5] Eruptions at the volcano are increasing in intensity, and some reports indicate that large explosions have begun.[6][7] Should pyroclastic flows occur, nearby villages will be at very high risk, but many villagers have defied the dangers posed by the volcano and returned to their villages, saying that they needed to tend their live-stock and crops.[8] On May 16 activity has calmed down but scientists are warning it still poses a threat.[9]
On May 27, a 6.2 magnitude earthquake struck roughly 30 miles southwest of Merapi, killing at least 5,000 and leaving at least 200,000 people homeless in the Yogyakarta region, heightening fears that Merapi will "blow".[10] The quake did not appear to be a long-period oscillation, a seismic disturbance class that is increasingly associated with major volcanic eruptions. A further 11,000 villagers were evacuated on June 6 as lava and superheated clouds of gas poured repeatedly down its upper slopes

1992 eruption of merapi

1992 saw an eruption begin at Mount Merapi which continued for the next ten years. During this time, a lava dome was extruded, growing by up to half a metre per day. In 1994, the dome reached the edge of the crater, and from then on, rockfall from the dome produced frequent pyroclastic flows. In late 1994 almost the entire dome collapsed, generating very large pyroclastic flows, which travelled several kilometres from the summit and killed 43 people.
Following the large eruption of November 1994, a new dome formed in the crater, and small explosive eruptions continued for several years, generating scores of lava avalanches and pyroclastic flows every day. Eruptions ended in late 2002

Geological history of merapi

Merapi is the youngest in a group of volcanoes in southern Java.It is situated at a subduction zone, where the Indo-Australian Plate is sliding beneath the Eurasian Plate. It is one of at least 129 active volcanoes in Indonesia, part of the Pacific Ring of Fire - a section of fault lines stretching from the Western Hemisphere through Japan and South East Asia.[1] Stratigraphic analysis reveals that eruptions in the Merapi area began about 400,000 years ago, and from then until about 10,000 years ago, eruptions were typically effusive, and the outflowing lava emitted was basaltic. Since then, eruptions have become more explosive, with viscous andesitic lavas often generating lava domes. Dome collapse has often generated pyroclastic flows, and larger explosions, which have resulted in eruption columns, have also generated pyroclastic flows through column collapse.
Typically, small eruptions occur every two to three years, and larger ones every 10-15 years or so. Notable eruptions, often causing many deaths, have occurred in 1006, 1786, 1822, 1872 (the most violent eruption in recent history), and 1930—when thirteen villages were destroyed and 1400 people killed by pyroclastic flows.
A very large eruption in 1006 is claimed to have covered all of central Java with ash. The volcanic devastation is claimed to have led to the collapse of the Hindu Kingdom of Mataram, however there is insufficient evidence from that era for this to be substantiated.
Merapi continues hold particular significance for the Javanese: it is one of four places where officials from the royal palaces of Yogyakarta and Solo make annual offerings to placate the ancient Javanese spirits.

Mount Merapi

Mount Merapi, Gunung Merapi in Indonesian language, is a conical volcano located on the border between Central Java and Yogyakarta, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. Its name means Mountain of Fire. It is very close to the city of Yogyakarta, and thousands of people live on the flanks of the volcano, with villages as high as 1700 m above sea level.
Several of its eruptions have caused fatalities. It was erupting from 1992 to 2002, and a particularly large explosion killed 43 people in 1994. It began erupting again in 2006, and scientists believe a large eruption is imminent. In light of the hazards it poses to populated areas, it has been designated a Decade Volcano.
