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.

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 ...

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] |
Tsunami Warning System
A tsunami warning system (TWS) is used to detect tsunamis in advance and issue the warnings to prevent loss of life and damage to property. It is made up of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to permit evacuation of the coastal areas. There are two distinct types of tsunami warning systems: international and regional. When operating, seismic alerts are used to instigate the watches and warnings; then, data from observed sea level height (either shore-based tide gauges or DART buoys) are used to verify the existence of a tsunami. Other systems have been proposed to augment the warning procedures; for example, it has been suggested that the duration and frequency content of t-wave energy (which is earthquake energy trapped in the ocean SOFAR channel) is indicative of an earthquake's tsunami potential. History and forecasting The first rudimentary system to alert communities of an im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Time In Indonesia
The Indonesian Archipelago geographically stretches across four time zones from UTC+06:00 in Aceh to UTC+09:00 in Papua. However, the Indonesian government recognises only three time zones in its territory, namely: *Western Indonesia Time (WIB) — seven hours ahead ( UTC+07:00) of the Coordinated Universal Time (UTC); *Central Indonesia Time (WITA) — eight hours ahead ( UTC+08:00) of UTC; *Eastern Indonesia Time (WIT) — nine hours ahead ( UTC+09:00) of UTC. The boundary between the Western and Central time zones was established as a line running north between Java and Bali through the provincial boundaries of West and Central Kalimantan. The border between the Central and Eastern time zones runs north from the eastern tip of Indonesian Timor to the eastern tip of Sulawesi. Daylight saving time (DST) is no longer observed anywhere in Indonesia. Current usage In Indonesia Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania b ...

Eruptions
Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three different types of eruptions: * Magmatic eruptions are the most well-observed type of eruption. They involve the decompression of gas within magma that propels it forward. * Phreatic eruptions are driven by the superheating of steam due to the close proximity of magma. This type exhibits no magmatic release, instead causing the granulation of existing rock. * Phreatomagmatic eruptions are driven by the direct interaction of magma and water, as opposed to phreatic eruptio ...
