San Salvador (volcano)
The San Salvador Volcano (also known as Quezaltepeque or El Boquerón) is a stratovolcano situated northwest to the city of San Salvador. The crater has been nearly filled with a relatively newer edifice, the Boquerón volcano. San Salvador is adjacent to the volcano and the western section of the city actually lies among its slopes. Due to this close proximity, any geological activity of the volcano, whether eruptive or not, has the potential to result in catastrophic destruction and death to the city. Despite this, the volcano is iconic of the city, and several TV and radio antennas are situated on the El Picacho peaks and the crater of Boqueron. El Picacho, the prominent peak is the highest elevation (1,960 meters altitude). Boquerón edifice The main edifice, known as the Boquerón edifice, formed between 700 and 1,000 years ago, filling up a former caldera. The crescent-shaped ridge on the northeast side of the volcano is a remnant of the caldera rim. The lavas of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joya De Cerén
Joya de Cerén (''Jewel of Cerén'' in the Spanish language) is an archaeological site in La Libertad Department, El Salvador, featuring a pre-Columbian Maya farming village. The ancient Maya site of Joya de Cerén is located in the Zapotitán Valley, 36 kilometers northwest of San Salvador, El Salvador.Castellanos, p. 94. It is often referred to as the "Pompeii of the Americas", in comparison to the famed Ancient Roman ruins. This site is known for the excellent preservation of a Classic period settlement that was rapidly buried by the ashfall of an eruption of the Loma Caldera around AD 600. The relative abundance of paleoethnobotanical remains recovered at Joya de Cerén in comparison to other ancient Maya archaeological sites make Joya de Cerén particularly significant in the study of everyday life of ancient Maya agricultural communities. Of importance was the discovery of a manioc field, the first instance of manioc cultivation identified at a New World archaeological si ...

Nejapa
Nejapa is a municipality in the San Salvador department of El Salvador. Traditions Las Bolas De Fuego One of the major traditions of Nejapa is ''Las Bolas De Fuego'' ("Balls of Fire"), celebrated August 31st. The celebration has two origins, one historical and the other religious. The historical version explains that the local volcano El Playon erupted in November 1658 and forced the villagers of the old Nejapa village (known as Nixapa) to flee and settle at its current location. The religious version explains how Saint Jerome fought the Devil with Fire Balls. Participants engage in a planned fire-fight to commemorate the volcanic eruption in 1922. Although this is quite dangerous, few bad injuries have been reported. External linksAlcaldía Municipal de Nejapa [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1917 San Salvador Earthquake
The 1917 San Salvador earthquake occurred on June 7 at 18:55 local time near the Salvadoran capital. The hypocenter of the 6.7 was at a shallow depth of , and occurred along a shallow crustal fault near San Salvador. The earthquake caused significant destruction of the city and left approximately 1,050 dead. It was followed by an eruption on San Salvador that killed another 1,100. Only behind the earthquake of 1986, it is the second deadliest in El Salvador's history. Earthquake El Salvador lies atop the Chortis Block, near its western margin. It is bounded by the Motagua– Polochic Fault between the North American–Caribbean transform boundary. Along the western margin, at the Middle America Trench, the Cocos Plate subducts beneath it at /year. Subduction produces volcanism along the Central America Volcanic Arc (CAVA) which stretches from Costa Rica to Guatemala. Within the shallow crust of El Salvador, seismicity is associated with the El Salvador Fault Zone (ESFZ), a shea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Crater Lake
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the upper portion of the lake is contained only by its adjacent natural volcanic dam; continued leakage through or surface outflow ac ...

Cinder Cone
A cinder cone (or scoria cone) is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as either cinders, clinkers, or scoria around the vent to form a cone that often is symmetrical; with slopes between 30 and 40°; and a nearly circular ground plan. Most cinder cones have a bowl-shaped crater at the summit. Mechanics of eruption Cinder cones range in size from tens to hundreds of meters tall and often have a bowl-shaped crater at the summit. They are composed of loose pyroclastic material (cinder or scoria), which distinguishes them from ''spatter cones'', which are composed of agglomerated volcanic bombs. The pyroclastic material making up a cinder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
