El Salvador
El Salvador (; , meaning " The Saviour"), officially the Republic of El Salvador ( es, República de El Salvador), is a country in Central America. It is bordered on the northeast by Honduras, on the northwest by Guatemala, and on the south by the Pacific Ocean. El Salvador's capital and largest city is San Salvador. The country's population in 2022 is estimated to be 6.5 million. Among the Mesoamerican nations that historically controlled the region are the Lenca (after 600 AD), the Mayans, and then the Cuzcatlecs. Archaeological monuments also suggest an early Olmec presence around the first millennium BC. In the beginning of the 16th century, the Spanish Empire conquered the Central American territory, incorporating it into the Viceroyalty of New Spain ruled from Mexico City. However the Viceroyalty of Mexico had little to no influence in the daily affairs of the isthmus, which was colonized in 1524. In 1609, the area was declared the Captaincy General of Guatemala by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caribbean Basin
In Geography, the Caribbean Basin is generally defined as the area running from Florida westward along the Gulf coast, then south along the Mexican coast through Central America and then eastward across the northern coast of South America. This region includes the islands of the archipelago of the West Indies. Bermuda is also included within the region even though it is in the west-central Atlantic, due to its common cultural history created by European colonization of the region, and in most of the region by the presence of a significant group of African descent. History The Caribbean basin as a region may be said to have its origins in the migrations of the Caribs from the Orinoco Valley in modern Venezuela into the Caribbean Sea beginning around 1200, which created an intercommunicating zone that connected places as far north as Puerto Rico, Hispaniola (modern Haiti and the Dominican Republic) and Jamaica to the mid reaches of the Orinoco River. The Spanish entered the reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Ana Volcano
The Santa Ana Volcano or Ilamatepec ( es, volcán de Santa Ana) is a large stratovolcano located in the Santa Ana department of El Salvador. At above sea level, it is the highest volcano in the country. It is located immediately west of Coatepeque Caldera. The volcano was the inspiration for one of the active volcanoes in Antoine de Saint-Exupéry's famous French novella (The Little Prince), based on his life with his Salvadoran wife Consuelo de Saint Exupéry, who was The Rose in the story. Geography The summit of Santa Ana features four nested calderas and volcanic craters, with the innermost containing a small crater lake. Collapse of the summit during the late Pleistocene (inferring from underlying soil samples, the upper age limit is no more than 57,000 years ago) produced a massive debris avalanche that reached the Pacific Ocean, forming the Acajutla Peninsula. Subsequent eruptions have largely rebuilt the edifice. There have been numerous historical eruptions s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Izalco (volcano)
Izalco is an active stratovolcano on the side of the Santa Ana Volcano, which is located in western El Salvador. It is situated on the southern flank of the Santa Ana volcano. Izalco erupted almost continuously from 1770 (when it formed) to 1958 earning it the nickname of "Lighthouse of the Pacific", and experienced a flank eruption in 1966. During an eruption in 1926, the village of Matazano was buried and 56 people were killed. The volcano erupted on highly arable land which was used for the production of coffee, cacao, and sugar cane. Geology and mineralogy The lava historically erupted from Izalco consists of Vesicular texture, vesicular Vitrophyre, vitrophyric olivine basalts. Izalco's formation was preceded by fumarole, fumorolic activity in 1658, before Izalco was born in 1770. Today, Izalco experiences only fumarolic activity in the form of rainwater seeping into the volcano and contacting hot rocks, rather than steam emissions from underground gases. The fumarole de ...

1986 San Salvador Earthquake
The 1986 San Salvador earthquake occurred at on October 10 with a moment magnitude of 5.7 and a maximum Mercalli intensity of IX (''Violent''). The shock caused considerable damage to El Salvador's capital city of San Salvador and surrounding areas, including neighboring Honduras and Guatemala. Earthquake The 1986 San Salvador earthquake occurred within the upper crust of the Caribbean Plate along the Central American volcanic chain. It was a result of left-lateral strike slip faulting perpendicular to the Central American volcanic chain. The earthquake also caused landslides located in the San Salvador area. Damage and response The earthquake caused between 1,000 and 1,500 deaths, 10,000 injuries, and left 200,000 homeless. 5] Shallow shocks directly under San Salvador caused the destruction of multiple structures. San Salvador's children's hospital, a marketplace, many restaurants and buildings, and shanty towns were significantly damaged or destroyed. In response, then ...

1982 El Salvador Earthquake
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

San Andreas Fault
The San Andreas Fault is a continental transform fault that extends roughly through California. It forms the tectonics, tectonic boundary between the Pacific Plate and the North American Plate, and its motion is Fault (geology)#Strike-slip faults, right-lateral strike-slip (horizontal). The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. The slip rate along the fault ranges from /yr. It was formed by a transform boundary. The fault was identified in 1895 by Professor Andrew Lawson of University of California, Berkeley, UC Berkeley, who discovered the northern zone. It is often described as having been named after San Andreas Lake, a small body of water that was formed in a valley between the two plates. However, according to some of his reports from 1895 and 1908, Lawson actually named it after the surrounding San Andreas Valley. Following the 1906 San Francisco earthquake, Lawson concluded that the fault extende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American Plate
The North American Plate is a tectonic plate covering most of North America, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores. With an area of , it is the Earth's second largest tectonic plate, behind the Pacific Plate (which borders the plate to the west). It extends eastward to the Mid-Atlantic Ridge and westward to the Chersky Range in eastern Siberia. The plate includes both continental and oceanic crust. The interior of the main continental landmass includes an extensive granitic core called a craton. Along most of the edges of this craton are fragments of crustal material called terranes, which are accreted to the craton by tectonic actions over a long span of time. It is thought that much of North America west of the Rocky Mountains is composed of such terranes. Boundaries The southern boundary with the Cocos Plate to the west and the Caribbean Plate to the east is a transform fault, represented by the Swan Islands Transform Fault unde ...

Geyser
A geyser (, ) is a spring characterized by an intermittent discharge of water ejected turbulently and accompanied by steam. As a fairly rare phenomenon, the formation of geysers is due to particular hydrogeological conditions that exist only in a few places on Earth. Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma. Generally, surface water works its way down to an average depth of around where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent (a hydrothermal explosion). A geyser's eruptive activity may change or cease due to ongoing mineral deposition within the geyser plumbing, exchange of functions with nearby hot springs, earthquake influences, and human intervention. Like many other natural phenomena, geysers are not unique to Earth. Jet-like eruptions, often referred to as cryoge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle America Trench
The Middle America Trench is a major subduction zone, an oceanic trench in the eastern Pacific Ocean off the southwestern coast of Middle America, stretching from central Mexico to Costa Rica. The trench is 1,700 miles (2,750 km) long and is 21,880 feet (6,669 m) at its deepest point. The trench is the boundary between the Rivera, Cocos, and Nazca plates on one side and the North American and Caribbean plates on the other. It is the 18th-deepest trench in the world. Many large earthquakes have occurred in the area of the Middle America Trench. Division The Middle America Trench can be divided into a northern and a southern section. The division, however, is not the same in its seaward side and its landward side. In the seaward side, the northern section, called the Acapulco Trench, runs from Jalisco to the Tehuantepec Ridge, and the southern section, called the Guatemala Trench, runs from the Tehuantepec Ridge to the Cocos Ridge. On the landward side, the division is dem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...
