Chichontepec
San Vicente (also known as Chichontepec or Las Chiches) is a stratovolcano in central El Salvador. It is located next to the town of San Vicente (hence the name) and is the second highest volcano in El Salvador. In the indigenous language Nahuat, Chichontepec means ''the mountain of the two breasts'', because its double summit resembles a woman's bosom. The volcano has two craters, one located in each summit, although not exactly at the top. Dense vegetation covers both summits. Numerous hot springs and fumaroles are found on the northern and western flanks of the volcano. To the northeast, at 820 metres in a ravine of 180 metres longitude, there are fumaroles—fountains of clear and muddy water or small volcanoes of mud. The last significant eruption occurred more than 1,700 years ago. The volcano may have had a very long history of repeated, and sometimes violent, eruptions, and at least once a large section of the volcano collapsed in a massive landslide. On August 9, 19 ...

San Vicente, El Salvador
San Vicente () is a municipality in the San Vicente department of El Salvador. It was founded by 50 Spanish families in 1635 under the Tempisque tree, which is still standing today. Historic sites One point of interest is the Tower of San Vicente, designed by French Architect Eugenio Basilio Crepiat (the Spanish version of his name), located at the center of the city in Cañas Park. It was damaged by an earthquake in 2001. Repairs have since been made, and the tower is once again the hub of many festivities. Another point of interest is water complex "Amapulapa" which is a water park that has multiple pools a water cascade and multiple restaurants and bars. The city has several local festivals, which take place at Cañas Park. Among these are the gastronomic festivals, which are usually held every month. Religion San Vicente is also the seat of the Roman Catholic Diocese of San Vicente The Diocese of San Vicente ( la, Dioecesis Sancti Vincentii) is a Latin Church ecclesiastical ...

Hot Spring
A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through faults to hot rock deep in the Earth's crust. In either case, the ultimate source of the heat is radioactive decay of naturally occurring radioactive elements in the Earth's mantle, the layer beneath the crust. Hot spring water often contains large amounts of dissolved minerals. The chemistry of hot springs ranges from acid sulfate springs with a pH as low as 0.8, to alkaline chloride springs saturated with silica, to bicarbonate springs saturated with carbon dioxide and carbonate minerals. Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had its ...

Aviateca Flight 901
Aviateca Flight 901 was a Boeing 737-200 (registration N125GU) that crashed into the San Vicente volcano in El Salvador on approach to the airport on 9 August 1995. The accident killed all 65 passengers and crew on board. It was the deadliest aviation disaster to occur in El Salvador. Accident Aviateca Flight 901 took off on a nighttime flight from La Aurora International Airport in Guatemala City, Guatemala, to El Salvador International Airport in San Salvador, El Salvador. There were 58 passengers and 7 crew on board. The flight crew consisted of 39-year-old Captain Axel Byron Herrera, 36-year-old First Officer Victor Francesco Salguero, three Flight Attendants and two Aviateca staffers. After a 20-minute flight the crew of Flight 901 contacted air traffic control at their destination, El Salvador International Airport. The controller informed them that there was a thunderstorm with heavy rain over the airport and instructed them to fly over the storm and start their ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California.

Fumarole
A fumarole (or fumerole) is a vent in the surface of the Earth or other rocky planet from which hot volcanic gases and vapors are emitted, without any accompanying liquids or solids. Fumaroles are characteristic of the late stages of volcanic activity, but fumarole activity can also precede a volcanic eruption and has been used for eruption prediction. Most fumaroles die down within a few days or weeks of the end of an eruption, but a few are persistent, lasting for decades or longer. An area containing fumaroles is known as a fumarole field. The predominant vapor emitted by fumaroles is steam, formed by the circulation of groundwater through heated rock. This is typically accompanied by volcanic gases given off by magma cooling deep below the surface. These volcanic gases include sulfur compounds, such as various sulfur oxides and hydrogen sulfide, and sometimes hydrogen chloride, hydrogen fluoride, and other gases. A fumarole that emits significant sulfur compounds is some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breast
The breast is one of two prominences located on the upper ventral region of a primate's torso. Both females and males develop breasts from the same embryological tissues. In females, it serves as the mammary gland, which produces and secretes milk to feed infants. Subcutaneous fat covers and envelops a network of ducts that converge on the nipple, and these tissues give the breast its size and shape. At the ends of the ducts are lobules, or clusters of alveoli, where milk is produced and stored in response to hormonal signals. During pregnancy, the breast responds to a complex interaction of hormones, including estrogens, progesterone, and prolactin, that mediate the completion of its development, namely lobuloalveolar maturation, in preparation of lactation and breastfeeding. Humans are the only animals with permanent breasts. At puberty, estrogens, in conjunction with growth hormone, cause permanent breast growth in female humans. This happens only to a much lesser ...

Volcanic Crater
A volcanic crater is an approximately circular depression in the ground caused by Volcano, volcanic activity. It is typically a bowl-shaped feature containing one or more vents. During Types of volcanic eruptions, volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava. A volcanic crater can be of large dimensions, and sometimes of great depth. During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera. Geomorphology In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form. Other volcanic craters may be found on the flanks of volcanoe ...

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] |
Double Summit
A double summit, double peak, twin summit, or twin peak refers to a mountain or hill that has two summits, separated by a col or saddle. One well-known double summit is Austria’s highest mountain, the Großglockner, where the main summit of the Großglockner is separated from that of the Kleinglockner by the Glocknerscharte col in the area of a geological fault. Other double summits have resulted from geological folding. For example, on Mont Withrow in British Columbia, resistant sandstones form the limbs of the double summit, whilst the softer rock in the core of the fold was eroded.{{cite web , url=http://gsc.nrcan.gc.ca/natmap/cf/intro_e.php , title=Mt.
