Welcome to Indonesia Archipelago

The archipelago of Indonesia consists of more than 13,000 islands, spread over an area that is similar in size to that of the continental United States. It is the country with the greatest number and density of active volcanoes.

Most volcanoes in Indonesia belong to the Sunda Volcanic Arc, streching over 3,000 kilometers from NW Sumatra to the Banda Sea. This volcanic arc results from the subduction of Indian Ocean crust beneath the Asian Plate and includes 76% of the region's volcanoes. To the NNW, the basaltic volcanism of the Andaman Islands results from short spreading centers, and to the east the Banda Arc reflects Pacific Ocean crust subducted westward. North of this arc, the tectonic setting is much more complex: several fragments of plates are converging  to form multiple subduction zones, mainly oriented N-S. These produce the Sulawesi-Sangihe volcanoes on the west and Haimahera on the east of the collision zone.

Indonesia leads the world in many volcano statistics. It has the largest number of historically active volcanoes (76), its total of 1,171 dated eruptions is only narrowly exceeded by Japan's 1,274, although not much is know about the volcanic activity in the time before European colonialists arrived from the 15th century on. Indonesia has suffered the highest numbers of eruptions producing fatalities, damage to arable land, mudflows, tsunamis, domes, and pyroclastic flows. Four-fifths of Indonesian volcanoes with dated eruptions have erupted in this century.

Two of the most devastating volcanic eruptinos in historic time took place in Indonesia: the enormous eruption of Tambora in 1815,- the largest known eruption of the world during historical times,- had such far-reaching effects on the climate that for instance Europe was to experience 1816 as the year without summer. In 1883, the disastrous eruption of Krakatau carved itself deeply into the collective memory of mankind. The eruption of Krakatau was followed by severe tsunamis that killed about 30-40,000 people.

In 1920, a volcano survey was established by the Dutch-led government, leading to much improved volcano monitoring and reporting. The Volcanological Survey of Indonesia (VSI) now operates a network of 64 volcano observatories continuously monitoring 59 volcanoes.

Krakatoa or Krakatau

The legendary Krakatau lies about 60 km from Carita Beach. Today only a small part of the origin volcano remains, but when Krakatau blew itself apart in 1883, in one of the world’s greatest and the most catastrophic eruptions, the effects were recorded far beyond Sunda strait and it achieved instant and lasting infamy. For centuries Krakatau had been a familiar nautical landmark for much of the world’s maritime traffic  which was funneled through the narrow Sunda Strait. The volcano had been dormant since 1680 and was widely regarded as extinct but from may through to early August in 1883 passing ship reported moderate activity, by 26 August Krakatau was raging and explosions become more and more violent. At 10 am on 27 August Krakatau erupted with the biggest bang ever recorded on earth. On the island Rodriguez more than 4600 km to the SW, police chief reported hearing booming of “ heavy guns from eastward’; in Alice Spring, 3500 km to the SE , Resident also reported hearing strange explosions from the NW. With its cataclysmic explosion, Krakatau sent up a recorded column of ash 80 km high and threw to air nearly 20 cubic km of rock. Ash felt on Singapore 840 km to the North and on ships as far as 600 km away; the darkness covered Sunda Strait from 10 am on 27 until dawn the next day. Giant tsunamis more than 40 meters high swept over the nearby shores of Java and Sumatra; and the sea wave’s passage was recorded far from Krakatau reaching Aden in 12 hrs over a distance ‘ traveled by good steamer in 12 days. Coastal java and Sumatra were devastated; 165 villages were destroyed and more than 40.000 people killed. The following days telegram sent to Singapore from Batavia (160 km east Krakatau) reported odd details such as’ fish dizzy and caught with glee by native’! Three months later the dust thrown into the atmosphere caused such vivid sunsets in USA that fire engines were being called out to quench the apparent fires and for three years it continued to circle the earth, creating strange  and spectacular sunset.

Ujung Kulon National Park

The park's 120.551 hectares are divided into 76.214 ha of land and 44.337 ha of surrounding reef and sea. It can roughly be separated into three areas: the triangular shaped Ujung kulon Peninsula, the Gunung Honje Range to the east of the peninsula's isthmus and the island of Panaitan to the northwest. The highest points in the park are the 620 meters Gunung Honje, the Gunung Payung Range peaks of up to 500 meters and Panaitan Island 's Gunung Raksa at 320 meters. In the central section of the Peninsula is a large region of wilderness known as the Talanca Plateau which reaches 140 meters above sea level, however most consist of low rolling terrain seldom more than 50 meters above sea level.The park surrounded by unusually warm water, seldom varying from between 29C to 30C. The coastlines of the park are molded by the sea around them, battered by Indian Ocean; the long sandy beaches of the south coast are backed by dunes, lagoons and forest broken by rocky outcrops  a wild and wind swept shore line.The west coast's reef-lined shore has cliffs, promontories and towering sea-stacks along sand and boulder beaches overhung by forest, creating the most spectacular coastline in the park.On the north coast, the sheltered tropical straits lap upon beaches of white sands and coral banks with islands, estuaries, swamps and forest lined shores.Along each coastline is variety of seascape which in all their diversity, offer a wide range of absorbing shoreline experiences

Baduy Tribe

The Baduy  who call themselves Kanekes, are a traditional community living in the western part of the Indonesian province of Banten, near Rangkasbitung.Ethnically the Baduys belong to the Sundanese ethnic group. Their racial, physical and linguistic traits bear much resemblance to the rest of the Sundanese people; however, the difference is in their way of life. Baduy people resist foreign influences and vigorously preserve their ancient way of life, while modern Sundanese are more open to foreign influences and a majority are Muslims.

The Baduy are divided into two sub-groups; the Baduy Dalam (Inner Baduy), and the Baduy Luar (Outer Baduy). No foreigners were allowed to meet the Inner Baduy, though the Outer Baduy do foster some limited contacts with the outside world. The origin of the word Baduy may come from the term "Bedouin", although other sources claim the source is a name of a local river.The religion of the Baduy is known as Agama Sunda Wiwitan, a combination of traditional beliefs and Hinduism. However, due to lack of interaction with the outside world, their religion is more related to Kejawen Animism, though they still retain many elements of Hindu-Buddhist religion influences, like the terms they use to define things and objects, and the rituals in their religious activities.

Sunda Strait Tsunami

The Volcanological Survey of Indonesia (PVMBG) recorded a dramatic increase in activity of Anak Krakatau. On 22 December, from 12.00 to 18.00 local time, a total of 423 eruptions were recorded by the agency. The danger level of the volcano was increased to Level 2. Authorities warned people not to conduct any activities within two kilometres (1.2 mi) of the volcano.
On 22 December 2018, at 21:03 local time (14:03 UTC), Anak Krakatau erupted and damaged local seismographic equipment, though a nearby seismographic station detected continuous tremors. The eruption caused the collapse of the southwest portion of the volcano, which triggered a tsunami. Officials stated that approximately 64 hectares (160 acres) of the volcano had collapsed into the ocean. The collapse caused the height of the volcano to be reduced from 338 to 110 metres (1,109 to 361 ft).
The Meteorology, Climatology, and Geophysical Agency (BMKG) detected a tsunami around 21:27 local time (14:27 UTC) at the western coast of Banten, even though the agency had not detected any preceding tectonic events. The Indonesian National Agency for Disaster Countermeasure (BNPB) spokesman Sutopo Purwo Nugroho said, "Dozens of buildings were destroyed by the wave, which hit beaches in Lampung and Banten about 21:30 local time (14:30 UTC) on Saturday."[8] According to The Jakarta Post, authorities said that the tsunami "may have been triggered by an abnormal tidal surge due to a full Moon and an underwater landslide following the eruption of Anak Krakatau." The Agency initially refused to label the event as a tsunami, claiming that it was a "normal" high tide and that no tsunami had occurred on the coast of Banten.
Previously, BMKG had issued a high wave warning for the waters of the strait. Tide gauges measured the tsunami at around 90 centimetres (35 in) in Serang and 30 centimetres (12 in) in Lampung, on top of the two-metre (6 ft 7 in) high tide.[18] While Indonesia possesses a tsunami warning system for tsunamis caused by earthquakes, there is none for volcanic tsunamis. Hence there were no early warnings. On 23 December, satellite data and helicopter footage confirmed that the southwest sector of the volcano had collapsed, which triggered the tsunami, and that the main volcanic conduit was erupting from underwater, producing Surtseyan-style activity.
The waves struck about 312.75 kilometres (194.33 mi) of coastline with various heights. In Carita, the waves reportedly struck with a height of at least two metres (6 ft 7 in), while in Tanjung Lesung a height of more than five metres (16 ft) was reported. Further surveys conducted on 31 December by the Ministry of Maritime Affairs and Fisheries, with assistance from Tohoku University and Chuo University, revealed that the tsunami struck the coastline of Banten and Lampung at a height of 13 metres (43 ft).
