2022 Sumatra Earthquake
On 25 February 2022, a moment magnitude 6.2 earthquake struck West Sumatra, Indonesia at a depth of . Preceded by one foreshock and followed by over 200 aftershocks, the mainshock had an epicenter at the foot of Mount Talakmau in Pasaman Regency. The mainshock was the result of strike-slip faulting along a previously unidentified segment of the Great Sumatran Fault. At least 27 people died, 457 were injured, and 19,221 others were displaced. It inflicted Rp. 780 million worth of damages. The heaviest damage was recorded at three villages around Mount Talakmau. Landslides and flash floods caused additional damage and casualties. Tectonic setting The west coast of Sumatra is dominated by the Sunda megathrust; a long convergent boundary where the Australian Plate subducts beneath the Burma Plate and Sunda Plate at a rate of per year. The subduction zone offshore Sumatra was responsible for several large earthquakes in 2004 and 2005. The subduction plate interface can r ...

Indonesian Rupiah
The rupiah (Currency symbol, symbol: Rp; ISO 4217, currency code: IDR) is the official currency of Indonesia. It is issued and controlled by Bank Indonesia. The name "Rupee, rupiah" is derived from the Sanskrit word for silver, (). Sometimes, Indonesians also informally use the word ("silver" in Indonesian language, Indonesian) in referring to rupiah in coins. The rupiah is divided into 100 ''cent (currency), sen'', although high inflation has rendered all coins and banknotes denominated in obsolete. Introduced in 1946 by Indonesian nationalists Indonesian National Revolution, fighting for independence, the currency replaced Japanese government-issued currency in the Dutch East Indies, a version of the Netherlands Indies gulden, which had been introduced during the Japanese occupation of the Dutch East Indies, Japanese occupation in World War II. In its early years, the rupiah was used in conjunction with other currencies, including a new version of the gulden introduced by th ...

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 ...

Earth Observatory Of Singapore
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar energy i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The hyphen-minus is the most commonly used type of hyphen, widely used in digital documents. It is the only character that looks like a minus sign or a dash in many character sets such as ASCII or on most keyboards, so it is also used as such. The name "hyphen-minus" derives from the original ASCII standard, where it was called "hyphen(minus)". The character is referred to as a "hyphen", a "minus sign", or a "dash" according to the context where it is being used. Description In early monospaced font typewriters and character encodings, a single key/code was almost always used for hyphen, minus, various dashes, and strikethrough, since they all have a roughly similar appearance. The current Unicode Standard specifies distinct characters for a number of different dashes, an unambiguous minus sign ("Unicode minus") at code point U+2212, and various types of hyphen including the unambiguous "Unicode hyphen" at U+2010 and the hyphen-minus at U+002D. When a hyphen is called for, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1943 Alahan Panjang Earthquakes
The 1943 Alahan Panjang earthquakes occurred on June 8 and June 9 UTC (June 9, 1943, local time) in Sumatra, then under Japanese occupation. This was an earthquake doublet (the shocks occurred at the same location on consecutive days). The first mainshock occurred on June 8 at 20:42 UTC. It ruptured the Suliti segment of the Sumatran Fault Zone. The magnitude was given as 7.2, or 7.1. The second mainshock occurred on June 9 at 03:06 UTC. It ruptured the Sumani segment of the Sumatran Fault Zone and perhaps the northwestern part of the Suliti segment. The magnitude was given as 7.5, or 7.4. Alahan Panjang was damaged in the earthquakes. Right lateral offsets were reported near the town of Solok. Near the Sumani segment, earthquake doublets occurred repeatedly. Similar earthquake doublet nearby include the earthquakes in 1926 and 2007.

1933 Sumatra Earthquake
The 1933 Sumatra earthquake or Liwa earthquake occurred in West Lampung Regency, Lampung Province, Indonesia on June 25. The earthquake had an estimated surface-wave magnitude () of 7.7 occurring at a shallow depth of 20 km. It had an epicenter onshore, devastating the city of Liwa. At least 76 people were reported killed, although the death toll may have been in the thousands. Aftershocks followed, including one which was strong enough to cause additional fatalities. The mainshock also triggered a nearby volcanic eruption two weeks later, killing some people. Tectonic setting The west coast of Sumatra is dominated by the Sunda megathrust; a 5,500 km long convergent boundary where the Australian Plate subducts beneath the Burma Plate and Sunda Plate at a rate of per year. Convergence along this plate boundary is highly oblique, severely deforming the overriding Sunda Plate, where it is accommodated by strike-slip motion along the Great Sumatran fault. The Great S ...

1995 Kerinci Earthquake
The 1995 Kerinci earthquake struck near Sungai Penuh in Jambi Province on the island of Sumatra, Indonesia. It earthquake occurred at 01:18 WIB (UTC +7) local time on October 7. The earthquake measured 6.7 on the moment magnitude scale, and 6.9–7.0 on the surface wave magnitude scale. Between 84 and possibly even 100 people were killed in the earthquake. An extimated 4,000 buildings collapsed or were seriously damaged while a further 5,000 suffered some damage. Earthquake The earthquake was associated with shallow strike-slip faulting along the Great Sumatran Fault, instead of thrust mechanism associated with the Sunda Megathrust to the west coast. It ruptured the Siulak segment of the fault which was also involved in a magnitude 7.3 earthquake in 1909. This segment of the fault had been quiet for an unusually long period prior to the 1995 earthquake. Impact The damage occurred mainly in the valley linear to the Great Sumatran Fault. Serious damage was reported north of L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Padang
Padang () is the capital and largest city of the Indonesian province of West Sumatra. With a Census population of 1,015,000 as of 2022, it is the 16th most populous city in Indonesia and the most populous city on the west coast of Sumatra. The Padang metropolitan area is the third most populous metropolitan area in Sumatra with a population of over 1.4 million. Padang is widely known for its Minangkabau culture, cuisine, and sunset beaches. The city had historically been a trading center since the pre-colonial era, trading in pepper and gold. The Dutch made contact with the city in the mid 17th century, eventually constructing a fortress and taking over control of the city from the Pagaruyung Kingdom. Save for several interruptions of British rule, Padang remained part of the Dutch East Indies as one of its major cities until Indonesian independence. In 1906, Padang along with Palembang became the first populated places in Sumatra to achieve city status (''gemeente''). Hi ...
