Indonesia travel : Krakatau can be reach from West Java or Kalianda in the Sumatran coast, Lampung 06
Krakatoa, or Krakatau (Indonesian: Krakatau), is a volcanic island situated in the Sunda Strait between the islands of Java and Sumatra in Indonesia. The name is also used for the surrounding island group comprising the remnants of a much larger island of three volcanic peaks which was obliterated in a cataclysmic 1883 eruption, unleashing huge tsunamis (killing more than 36,000 people) and destroying over two-thirds of the island. The explosion is considered to be the loudest sound ever heard in modern history, with reports of it being heard up to 3,000 miles (4,800 km) from its point of origin. The shock waves from the explosion were recorded on barographs around the globe.
In 1927 a new island, Anak Krakatau, or "Child of Krakatoa", emerged from the caldera formed in 1883 and is the current location of eruptive activity.
The most notable eruptions of Krakatoa culminated in a series of massive explosions over August 26–27, 1883, which were among the most violent volcanic events in recorded history.
With an estimated Volcanic Explosivity Index (VEI) of 6, the eruption was equivalent to 200 megatons of TNT (840 PJ) —about 13,000 times the nuclear yield of the Little Boy bomb (13 to 16 kt) that devastated Hiroshima, Japan, during World War II, and four times the yield of Tsar Bomba (50 Mt), the most powerful nuclear device ever detonated.
The 1883 eruption ejected approximately 25 cubic kilometers (6 cubic miles) of rock. The cataclysmic explosion was heard 4,800 kilometers (3,000 miles) away in Alice Springs, as well as on the island of Rodrigues near Mauritius, 4,653 kilometers (2,891 miles) to the west.
According to the official records of the Dutch East Indies colony, 165 villages and towns were destroyed near Krakatoa, and 132 were seriously damaged. At least 36,417 people died, and many more thousands were injured, mostly from the tsunamis that followed the explosion. The eruption destroyed two-thirds of the island of Krakatoa.
Eruptions in the area since 1927 have built a new island at the same location, named Anak Krakatau (which is Indonesian for "Child of Krakatoa"). Periodic eruptions have continued since, with recent eruptions in 2009, 2010, 2011, and 2012. As of late 2011, this island has a radius of roughly 2 kilometers (1.2 mi), and a high point of about 324 meters (1,063 ft) above sea level, growing 5 meters (16 ft) each year.
Although there are earlier descriptions of an island in the Sunda Strait with a "pointed mountain," the earliest mention of Krakatoa by name in the western world was on a 1611 map by Lucas Janszoon Waghenaer, who labeled the island "Pulo Carcata" (pulo is the Sundanese word for "island"). About two dozen variants have been found, including Crackatouw, Cracatoa, and Krakatao (in an older Portuguese-based spelling). The first known appearance of the spelling Krakatau was by Wouter Schouten, who passed by "the high tree-covered island of Krakatau" in October 1658.
The origin of the Indonesian name Krakatau is uncertain. The Smithsonian Institution's Global Volcanism Program cites the Indonesian name, Krakatau, as the correct name, but says that Krakatoa is often employed. While Krakatoa is more common in the English-speaking world, the Indonesian Krakatau tends to be favored by others, including geologists.
A large part of the 1947 children's novel The Twenty-One Balloons by William Pene du Bois takes place on Krakatoa, where several families have established a wealthy and fanciful colony based on fictional diamond mines on the island.
Krakatoa has been featured as a subject and a part of the story in various television and film dramas. In the 1953 film Fair Wind to Java, an American sea captain and a pirate leader race one another to recover a fortune in diamonds hidden on Krakatoa, which begins its final eruption as they search the island for the treasure. The island was a prominent part of the plot of '"Crack of Doom," an episode of the Irwin Allen television series The Time Tunnel in 1966. It was also featured as the main part of the story line in the 1969 film, Krakatoa, East of Java (re-titled Volcano in a re-release in the 1970s), which depicts an effort to salvage a priceless cargo of pearls located perilously close to the erupting volcano. An Indonesian martial arts action film, Krakatau (1977), starring Dicky Zulkarnaen and Advent Bangun, also set their story around the mountain. In more recent years, it has been the subject of a 2006 television drama, Krakatoa: Volcano of Destruction and again in 2008 as Krakatoa.
