Apoyeque
Apoyeque is a pyroclastic shield, located in the Chiltepe Peninsula Natural Reserve in Nicaragua. It has a 2.8-km wide, 400-m-deep, lake-filled caldera. Geography Apoyeque is a volcanic complex that formed and occupies the Chiltepe Peninsula. It is part of the Chiltepe pyroclastic shield volcano, one of three ignimbrite shields on the Nicaraguan volcanic front. The lake at its center, Apoyeque lake ( Spanish: ''Laguna de Apoyeque'', also called ''Laguna de Apoyaque'',), its shore 100 meters below the peak of the caldera, at its bottom reaches down to sea level. Apoyeque, as well as the entire Chiltepe peninsula are part of the Managua administrative region, in close proximity to city of Managua, Nicaragua's capital. Immediately southeast of Apoyeque peak is the 2.5 × 3 kilometer-wide lake-filled Xiloá (Jiloá) maar, a part of the Apoyeque complex. Volcanology The last eruption of Apoyeque, in about 50 BC (+/- 100 years), was one of the largest explosions known in history, ...

Chiltepe Peninsula Natural Reserve
Chiltepe Peninsula Natural Reserve ( Spanish: ''Reserva Natural Península de Chiltepe'') is a nature reserve in Nicaragua. It is one of the 78 reserves which are officially under protection in the country. Located on the south shore of Lake Managua, it is 15 kilometers Northwest of Managua, the capital, and consequently a popular destination for visitors from the city. The peninsula was formed by Apoyeque Apoyeque is a pyroclastic shield, located in the Chiltepe Peninsula Natural Reserve in Nicaragua. It has a 2.8-km wide, 400-m-deep, lake-filled caldera.

Pyroclastic Shield
In volcanology, a pyroclastic shield or ignimbrite shield is an uncommon type of shield volcano. Unlike most shield volcanoes, pyroclastic shields are formed mostly of pyroclastic and highly explosive eruptions rather than relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano. They typically display low-angle flank slopes and often have a central caldera caused by large eruptions. Lava is commonly extruded after explosive activity has ended. The paucity of associated Plinian fall deposits indicates that pyroclastic shields are characterized by low Plinian columns. Pyroclastic shields are commonly known to form in the Central Andes of South America, as well as in Melanesia (the island of Bougainville alone has two). There are also pyroclastic shields in Africa, such as Emi Koussi in Chad.

Maar
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma). A maar characteristically fills with water to form a relatively shallow crater lake which may also be called a maar. The name comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany. Notes: * According to German Wikipedia's ''"Maar"'' article, in 1544 in his book ''Cosmographia'', Sebastian Münster (1488–1552) first applied the word "maar" (as ''Marh'') to the Ulmener Maar and the Laacher See. See: Sebastian Münster, ''Cosmographia'' (Basel, Switzerland: Heinrich Petri, 1544)p. 341. From p. 341: ''"Item zwen namhafftiger seen seind in der Eyfel / einer bey de schloß Ulmen / und ein ander bey dem Closter züm Laich / die seind sere tieff / habe kein ynflüß aber vil außflüß / die nennet man Marh unnd seind fischreich."''

Nicaragua
Nicaragua (; ), officially the Republic of Nicaragua (), is the largest country in Central America, bordered by Honduras to the north, the Caribbean to the east, Costa Rica to the south, and the Pacific Ocean to the west. Managua is the country's capital and largest city. , it was estimated to be the second largest city in Central America. Nicaragua's multiethnic population of six million includes people of mestizo, indigenous, European and African heritage. The main language is Spanish. Indigenous tribes on the Mosquito Coast speak their own languages and English. Originally inhabited by various indigenous cultures since ancient times, the region was conquered by the Spanish Empire in the 16th century. Nicaragua gained independence from Spain in 1821. The Mosquito Coast followed a different historical path, being colonized by the English in the 17th century and later coming under British rule. It became an autonomous territory of Nicaragua in 1860 and its northernmost part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISS038-E-35123 Apoyeque Volcano
The International Space Station (ISS) is the largest Modular design, modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), European Space Agency, ESA (Europe), and Canadian Space Agency, CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which Scientific research on the International Space Station, scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars.
