Parícutin
Parícutin (or Volcán de Parícutin, also accented Paricutín) is a cinder cone volcano located in the Mexican state of Michoacán, near the city of Uruapan and about west of Mexico City. The volcano surged suddenly from the cornfield of local farmer Dionisio Pulido in 1943, attracting both popular and scientific attention. Paricutín presented the first occasion for modern science to document the full life cycle of an eruption of this type. During the volcano's nine years of activity, scientists sketched and mapped it and took thousands of samples and photographs. By 1952, the eruption had left a cone and significantly damaged an area of more than with the ejection of stone, volcanic ash and lava. Three people were killed, two towns were completely evacuated and buried by lava, and three others were heavily affected. Hundreds of people had to permanently relocate, and two new towns were created to accommodate their migration. Although the larger region still remains highly ...

Nuevo San Juan Parangaricutiro
Nuevo San Juan Parangaricutiro or Parangaricutirimícuaro is a small village in the Mexican state of Michoacán near the Parícutin volcano. It is the municipal seat for the municipality of Nuevo Parangaricutiro. The city is called ''Nuevo'' (Spanish for "new") because the original San Juan Parangaricutiro was destroyed during the formation of the Parícutin volcano in 1943.Mexican volcanoes, Parícutin from the describing the destruction of both San Juan and Parícutin.

El Jorullo
El Jorullo is a cinder cone volcano in Michoacán, central Mexico, on the southwest slope of the central plateau, 33 miles (53 kilometers) southeast of Uruapan in an area known as the Michoacán-Guanajuato volcanic field. It is about 6 miles (10 km) east-northeast of La Huacana. Its current elevation is . El Jorullo has four smaller cinder cones which have grown from its flanks. The vents of El Jorullo are aligned in a northeast to southwest direction. Lava from these vents cover nine square km around the volcano. Later eruptions produced lavas that had higher silica contents making them thicker than the earlier basalts and basaltic andesite lavas. El Jorullo's crater is about 1,300 by 1,640 feet (400 by 500 m) wide and 490 feet (150 m) deep. El Jorullo is one of two known volcanoes to have developed in Mexico in recent history. The second, born about 183 years later, was named Parícutin after a nearby village that it eventually destroyed. P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pico De Tancítaro
Pico de Tancítaro, also known as Volcán Tancítaro, is a volcanic mountain in Mexico. It is located in Tancítaro municipality in Michoacán state. It is the highest peak in Michoacán. Geology Pico de Tancítaro is an andesitic- dacitic stratovolcano. It was active from 800,000 to 237,000 years ago, and is currently believed to be extinct. It is part of the much larger Michoacán–Guanajuato volcanic field. Portions of the volcanic field are still active. Parícutin is a young volcano located 11 km northeast of Pico de Tancítaro. It first erupted in 1943 and remained active and grew in size until 1952. Ecology Plant communities on the mountain include pine-oak forest, open pine forest, and montane mesophyll or cloud forest, with alpine grasslands, known as Zacatonal, at higher elevations."El Área de Protección de Flora y Fauna Pico de Tancítaro, proveedora de agua de al menos a 82 comunidades".

Michoacán
Michoacán, formally Michoacán de Ocampo (; Purépecha: ), officially the Free and Sovereign State of Michoacán de Ocampo ( es, Estado Libre y Soberano de Michoacán de Ocampo), is one of the 32 states which comprise the Federal Entities of Mexico. The state is divided into 113 municipalities and its capital city is Morelia (formerly called Valladolid). The city was named after José María Morelos, a native of the city and one of the main heroes of the Mexican War of Independence. Michoacán is located in Western Mexico, and has a stretch of coastline on the Pacific Ocean to the southwest. It is bordered by the states of Colima and Jalisco to the west and northwest, Guanajuato to the north, Querétaro to the northeast, the State of México to the east, and Guerrero to the southeast. The name Michoacán is from Nahuatl: ''Michhuahcān'' from ''michhuah'' ("possessor of fish") and -''cān'' (place of) and means "place of the fishermen" referring to those who fish on ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trans-Mexican Volcanic Belt
The Trans-Mexican Volcanic Belt ( es, Eje Volcánico Transversal), also known as the Transvolcanic Belt and locally as the (''Snowy Mountain Range''), is an active volcanic belt that covers central-southern Mexico. Several of its highest peaks have snow all year long, and during clear weather, they are visible to a large percentage of those who live on the many high plateaus from which these volcanoes rise. History The Trans-Mexican Volcanic Belt spans across Central-Southern Mexico from the Pacific Ocean to the Gulf of Mexico between 18°30'N and 21°30'N, resting on the southern edge of the North American Plate. This approximately 1000 kilometer long, 90–230 km broad structure is an east–west, active, continental volcanic arc; encompassing an area of approximately 160,000 km2. Over several million years, the subduction of the Rivera and Cocos plates beneath the North American Plate along the northern end of the Middle America Trench formed the Trans-Mexican Vol ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic pla ...

Seven Natural Wonders Of The World
Various lists of the Wonders of the World have been compiled from antiquity to the present day, in order to catalogue the world's most spectacular natural features and human-built structures. The Seven Wonders of the Ancient World is the oldest known list of this type, documenting the most remarkable man-made creations of classical antiquity; it was based on guidebooks popular among Hellenic sightseers and as such only includes works located around the Mediterranean rim and in the ancient Near East. The number seven was chosen because the Greeks believed it represented perfection and plenty, and because it reflected the number of planets known in ancient times (five) plus the Sun and Moon. Seven Wonders of the Ancient World The Greek historian Herodotus (484 – c. 425 BC) and the scholar Callimachus of Cyrene (c. 305–240 BC), at the Museum of Alexandria, made early lists of seven wonders. These lists have not survived, however, except as references in other writings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano (1997 Film)
''Volcano'' is a 1997 American disaster film directed by Mick Jackson and produced by Neal H. Moritz and Andrew Z. Davis. The film stars Tommy Lee Jones, Anne Heche, Don Cheadle, and Keith David and tells the story of an effort to divert the path of a dangerous lava flow through the streets of Los Angeles following the formation of a volcano at the La Brea Tar Pits. The storyline was conceived from a screenplay written by Jerome Armstrong and Billy Ray, and was inspired by the 1943 formation of the Parícutin volcano in Mexico. ''Volcano'' was released by 20th Century Fox in the United States on April 25, 1997. It received mixed reviews from critics and grossed $122 million worldwide on a $90 million budget. Plot In downtown Los Angeles, an earthquake strikes. Mike Roark, the new director of the city's Office of Emergency Management, insists on coming to work to help out with the crisis even though he has been on vacation with his daughter Kelly.

Cocos Plate
The Cocos Plate is a young oceanic tectonic plate beneath the Pacific Ocean off the west coast of Central America, named for Cocos Island, which rides upon it. The Cocos Plate was created approximately 23 million years ago when the Farallon Plate broke into two pieces, which also created the Nazca Plate. The Cocos Plate also broke into two pieces, creating the small Rivera Plate. The Cocos Plate is bounded by several different plates. To the northeast it is bounded by the North American Plate and the Caribbean Plate. To the west it is bounded by the Pacific Plate and to the south by the Nazca Plate. __TOC__ Geology The Cocos Plate was created by sea floor spreading along the East Pacific Rise and the Cocos Ridge, specifically in a complicated area geologists call the Cocos-Nazca spreading system. From the rise the plate is pushed eastward and pushed or dragged (perhaps both) under the less dense Caribbean Plate, in the process called subduction. The subducted leading edge he ...
