Iquique Nuestro
Iquique () is a port city and commune in northern Chile, capital of both the Iquique Province and Tarapacá Region. It lies on the Pacific coast, west of the Pampa del Tamarugal, which is part of the Atacama Desert. It has a population of 191,468 according to the 2017 census. It is also the main commune of Greater Iquique. The city developed during the heyday of the saltpetre mining in the Atacama Desert in the 19th century. Once a Peruvian city with a large Chilean population, it was conquered by Chile in the War of the Pacific (1879–1883). Today it is one of only two free ports of Chile, the other one being Punta Arenas, in the country's far south. History Although the city was founded in the 16th century, there is evidence of habitation in the area by the Chango people as early as 7,000 BC. During colonial times, Iquique was part of the Viceroyalty of Peru as much of South America was at the time, and remained part of Peruvian territory until the end of the 19th century. I ...

Potassium Nitrate
Potassium nitrate is a chemical compound with the chemical formula . This alkali metal nitrate salt is also known as Indian saltpetre (large deposits of which were historically mined in India). It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or ''nitre'' in the UK). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or ''saltpetre'' in the UK). Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color. Etymology Potassium nitrate, because of its early and global use and production, has many names. Hebrew and Egyptian words for it had the consonants n-t-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2014 Iquique Earthquake
The 2014 Iquique earthquake struck off the coast of Chile on 1 April, with a moment magnitude of 8.2, at 20:46 local time (23:46 UTC). The epicenter of the earthquake was approximately northwest of Iquique. The mainshock was preceded by a number of moderate to large shocks and was followed by a large number of moderate to very large aftershocks, including a M7.7 event on 3 April. The megathrust earthquake triggered a tsunami of up to that hit Iquique at 21:05 local time (00:05 UTC, 2 April). Similar-sized tsunamis were also reported to have hit the coasts of Pisagua and Arica. Geology A number of mid-sized quakes struck the same area in the preceding weeks. These quakes and the main tremor are associated with the boundary of the Nazca Plate and the South American Plate. Earthquake There was a cluster of earthquakes starting from the one occurring on 16 March with a magnitude of 6.7, and a large earthquake had been expected. The 8.2 earthquake was smaller than what wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2005 Tarapacá Earthquake
The 2005 Tarapacá earthquake occurred on June 13 at 22:44:33 UTC (18:44:33 local time). Its epicenter was located near Mamiña, in northern Chile about 125 km east-northeast of Iquique, affecting the Tarapacá Region and adjacent parts of Bolivia. It had a magnitude of 7.8 and a maximum felt intensity of VII (''Very strong'') on the Mercalli intensity scale. Tectonic setting Chile lies above the destructive plate boundary, where the Nazca Plate is being subducted beneath the South American Plate. In the Tarapacá region the plates converge at a rate of 78 mm per year. This boundary is associated with many large earthquakes, both along the plate interface and within the downgoing slab (Nazca Plate). Earthquake The earthquake was an intermediate-depth event, with a hypocentral depth of 115.6 km. The focal mechanism shows that this was a normal fault event, within the subducted Nazca Plate. Finite-fault modelling of the earthquake suggests that the fault plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1877 Iquique Earthquake
The 1877 Iquique earthquake occurred at 21:16 local time on 9 May (0:59 on 10 May UTC). It had a magnitude of 8.5 on the surface wave magnitude scale. Other estimates of its magnitude have been as high as 8.9 and 9.0 (based on the size of the tsunami). It had a maximum intensity of XI (Extreme) on the Mercalli intensity scale and triggered a devastating tsunami. A total of 2,385 people died, mainly in Fiji. Historical context Affected areas in what was then part of Bolivia, but is now the Antofagasta region of Chile, had during this period been subject to the Atacama border dispute between the two countries. Under the 1874 boundary treaty between Bolivia and Chile, the border between the two nations as of 1877 followed the 24th parallel south. The terms of that treaty required that Bolivia not levy taxes on Chilean companies mining nitrates between the 23rd and 24th parallels (including the city of Antofagasta) for 25 years, except for agreed duties to be shared betwee ...

1868 Arica Earthquake
The 1868 Arica earthquake occurred on 13 August 1868, near Arica, then part of Peru, now part of Chile, at 21:30 UTC. It had an estimated magnitude between 8.5 and 9.3. A tsunami (or multiple tsunamis) in the Pacific Ocean was produced by the earthquake, which was recorded in Hawaii, Japan, Australia, and New Zealand. Tectonic setting The earthquake occurred along the boundary between the Nazca Plate and the South American Plate. The earthquake was likely a result of thrust-faulting, caused by the subduction of the Nazca plate beneath the South American plate. The coasts of Peru and Chile have a history of great megathrust earthquakes originating from this plate boundary, such as the 1960 Valdivia earthquake and the 2010 Chile earthquake. Damage The earthquake caused almost complete destruction in the southern part of Peru, including Arica, Tacna, Moquegua, Mollendo, Ilo, Iquique, Torata and Arequipa, resulting in an estimated 25,000 casualties, and many shipwrecks.

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Nitrate
Sodium nitrate is the chemical compound with the formula . This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter. Sodium nitrate is a white deliquescent solid very soluble in water. It is a readily available source of the nitrate anion (NO3−), which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnics, smoke bombs and other explosives, glass and pottery enamels, food preservatives (esp. meats), and solid rocket propellant. It has been mined extensively for these purposes. History The first shipment of saltpeter to Europe arrived in England from Peru in 1820 or 1825, right after that country's independence from Spain, but did not find any buyers and was dumped at sea in order to avoid customs toll.Friedrich Georg Wieck, ' ...

Viceroyalty Of Peru
The Viceroyalty of Peru ( es, Virreinato del Perú, links=no) was a Spanish imperial provincial administrative district, created in 1542, that originally contained modern-day Peru and most of the Spanish Empire in South America, governed from the capital of Lima. The Viceroyalty of Peru was officially called the Kingdom of Peru. Peru was one of the two Spanish Viceroyalties in the Americas from the sixteenth to the eighteenth centuries. The Spanish did not resist the Portuguese expansion of Brazil across the meridian established by the Treaty of Tordesillas. The treaty was rendered meaningless between 1580 and 1640 while Spain controlled Portugal. The creation during the 18th century of Viceroyalties of New Granada and Río de la Plata (at the expense of Peru's territory) reduced the importance of Lima and shifted the lucrative Andean trade to Buenos Aires, while the fall of the mining and textile production accelerated the progressive decay of the Viceroyalty of Peru.

Changos
The Changos, also known as Camanchacos or Camanchangos, are an indigenous people or group of peoples who inhabited a long stretch of the Pacific coast from southern Peru to north-central Chile, including the coast of the Atacama desert. Although much of the customs and culture of the Chango people have disappeared and in many cases they have been considered extinct, in Chile they are legally recognized as an original indigenous people since 2020, and about 4,725 people self-declare that they belong to this ethnic group. History Definition and context of the Changos The culture originated in the 8,000-year-old Chinchorro tradition. Due to a combination of conquest and integration into other cultures and ethnicities, the Chango culture is now considered extinct. However, in Chile they are legally recognized as an original indigenous people since 2020, and about 4,725 people self-declare that they belong to this ethnic grou The Changos were not a distinct tribe or ethnic group; ra ...
