Krakatoa
Krakatoa (), also transcribed (), is a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The caldera is part of a volcanic island group (Krakatoa archipelago) comprising four islands. Two, Lang and Verlaten, are remnants of a previous volcanic edifice destroyed in eruptions long before the famous 1883 eruption; another, Rakata, is the remnant of a much larger island destroyed in the 1883 eruption. In 1927, a fourth island, Anak Krakatoa, or "Child of Krakatoa", emerged from the caldera formed in 1883. There has been new eruptive activity since the late 20th century, with a large collapse causing a deadly tsunami in December 2018. Historical significance The most notable eruptions of Krakatoa culminated in a series of massive explosions over 26–27 August 1883, which were among the most violent volcanic events in recorded history. With an estimated Volcanic Explosivity Index (VEI) of 6, the eruption was equivalen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1883 Eruption Of Krakatoa
The 1883 eruption of Krakatoa ( id, Letusan Krakatau 1883) in the Sunda Strait occurred from 20 May until 21 October 1883, peaking in the late morning hours of 27 August when over 70% of the island of Krakatoa and its surrounding archipelago were destroyed as it collapsed into a caldera. The eruption was one of the deadliest and most destructive volcanic events in recorded history. The explosion was heard away in Perth, Western Australia, and Rodrigues near Mauritius, away. The sound wave is recorded to have travelled around the globe seven times. At least 36,417 deaths are attributed to the eruption and the tsunamis it created. Significant additional effects were also felt around the world in the days and weeks after the volcano's eruption. Additional seismic activity was reported until February 1884, but any reports after October 1883 were dismissed by Rogier Verbeek's subsequent investigation into the eruption. Early phase In the years before the 1883 eruption, seismic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anak Krakatau
Anak Krakatoa ( id, Anak Krakatau)English translation and common name: ''Child of Krakatoa'' is a volcanic island in Indonesia. On 29 December 1927, Anak Krakatoa first emerged from the caldera formed in 1883 by the explosive volcanic eruption that destroyed the island of Krakatoa. There has been sporadic eruptive activity at the site since the late 20th century, culminating with a large underwater collapse of the volcano that caused a deadly Tsunami in December 2018. There has been subsequent activity since. Due to its young age, the island is one of several in the area that are of interest to, and the subject of extensive study by, volcanologists. History Background After the cataclysmic eruption of Krakatoa in 1883, Krakatoa Island lost approximately two-thirds of its body on the northwest side, obliterating the peaks of Perbuwatan and Danan, and leaving only the southern half of the island, including the Rakata volcano, as the last remnant of the original island.

Krakatoa Archipelago
The Krakatoa Archipelago is a small uninhabited archipelago of volcanic islands formed by the Krakatoa stratovolcano located in the Sunda Strait, nestled between the much larger islands of Java and Sumatra. As of 2018, the archipelago consists of four main islands: Verlaten (aka Sertung), Lang (aka Rakata Kecil, or Panjang), Rakata, and the currently volcanically active Anak Krakatoa. Together, the islands are a part of the Indonesian island arc system, created by the northeastward subduction of the Indo-Australian Plate. As part of a dynamic volcanic system, the islands have been continuously reshaped throughout recorded history, most notably in the 1883 eruption of Krakatoa. Politically, the Krakatoa Archipelago lies entirely within Lampung province of Indonesia, and forms a part of Ujung Kulon National Park. Geology Krakatoa is an active stratovolcano located in Indonesia, and lying on the far western rim of the Pacific Ring of Fire. Krakatoa is a notably powerful volc ...

Rakata
Rakata ( ), also called Greater Krakatau, is a partially collapsed stratovolcano on the Indonesian island of Krakatoa ( id, Krakatau) in the Sunda Strait between the islands of Sumatra and Java. Standing tall, it was the largest and southernmost of three volcanoes that formed the island Krakatoa (the others being Danan (volcano) and Perboewatan) and the only one not totally destroyed in the 1883 eruption. Rakata is the last remnant of the original island prior to its destruction. However, Rakata did lose its northern half in that eruption, leaving just its southern half. The exposed cliff is quite striking visually, partially of a large exposed dike terminating in a large lenticular extrusion at the middle of the almost vertical cliff. The feature has been called "the Eye of Krakatoa." Etymology Because the words ''Rakata'' and ''Krakatau'' are the same in Indonesian, both names are used interchangeably, leading to confusion in languages which distinguish between the two wor ...

2018 Sunda Strait Tsunami
The 2018 Sunda strait tsunami (Indonesian language, Indonesian: ''Tsunami Selat Sunda 2018'') occurred on 22 December 2018 at around 21:38 local time after large parts of the southwestern side of Anak Krakatoa collapsed onto its caldera. The landslide spawned a massive tsunami wave that struck multiple coastal regions in Banten and Lampung, including the popular tourist destination of Anyer. Lack of warnings on the arrival of the tsunami, coinciding with the Christmas and New Year Public holidays in Indonesia, holiday season in the nation, and night time setting in the area contributed to the large loss of life. With 426 deaths, the tsunami was the deadliest volcanic tsunami in recorded history in Indonesia since the 1883 eruption of Krakatoa, 1883 Sunda Strait tsunami, which originated from the same island.Benazir, Comfort, L.K., Luthfi, M, Supasri, A, Syamsidik.

Verlaten Island
Verlaten Island (Dutch: "Abandoned", "Deserted" or "Forsaken"; modern Indonesian: Sertung) is an island that was likely created in the 535 Eruption of Krakatoa. It is located in the Sunda Strait in Indonesia, between Java and Sumatra. It is part of the Krakatoa Archipelago, above the famous Krakatoa volcano. Other than some minor collapse in the southeast (closest to the main island of Krakatoa), Verlaten suffered little damage in the 1883 eruption. Instead, it grew almost 3 times in area due to pumice fall, although most of the gain was quickly eroded away. Form Verlaten is a rather low island with a hill in the middle. After the 1883 eruption, Verlaten developed a low spit of land to the north-east with a brackish Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater.

Sunda Strait
The Sunda Strait ( id, Selat Sunda) is the strait between the Indonesian islands of Java island, Java and Sumatra. It connects the Java Sea with the Indian Ocean. Etymology The strait takes its name from the Sunda Kingdom, which ruled the western portion of Java (an area covering the present day West Java, Jakarta, Banten, and some of western Central Java) from 669 to around 1579."Sunda Islands". Concise Dictionary of World Place-Names. John Everett-Heath. Oxford University Press 2005. Oxford Reference Online. Oxford University Press. The name also alludes to the Sundanese people native to West Java and Banten, as distinct from the Javanese people, who live mostly in Central and East Java. Geography Extending in a roughly southwest/northeast orientation, with a minimum width of at its northeastern end between Cape Tua on Sumatra and Cape Pujat on Java, the strait is part of the Java Sea. It is essentially triangular in shape, with two large bays on its northern side. It is al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lampung
Lampung (Lampung: ), officially the Province of Lampung ( id, Provinsi Lampung) is a province of Indonesia. It is located on the southern tip of the island of Sumatra. It has a short border with the province of Bengkulu to the northwest, and a longer border with the province of South Sumatra to the north. It is the original home of the Lampung people, who speak their own language, and possess their own written script. Its capital is Bandar Lampung. The province covers a land area of 35,376 sq.km and had a population of 7,608,405 at the 2010 census, 9,007,848 at the 2020 census, and 9,081,792 according to the official estimates for mid 2021,with three-quarters of that being descendants of Javanese, Madurese, and Balinese migrants. These migrants came from more densely populated islands, in search of available land, as well as being part of the national government's Indonesian transmigration program, of which Lampung was one of the earliest and most significant transmigrati ...

Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give ...

Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...
