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] |

Phreatomagmatic Eruption
Phreatomagmatic eruptions are volcanic eruptions resulting from interaction between magma and water. They differ from exclusively magmatic eruptions and phreatic eruptions. Unlike phreatic eruptions, the products of phreatomagmatic eruptions contain juvenile (magmatic) clasts.Heiken, G. & Wohletz, K. 1985. Volcanic Ash. University of California Press, Berkeley It is common for a large explosive eruption to have magmatic and phreatomagmatic components. Mechanisms Several competing theories exist as to the exact mechanism of ash formation. The most common is the theory of explosive thermal contraction of particles under rapid cooling from contact with water. In many cases the water is supplied by the sea, for example with Surtsey. In other cases the water may be present in a lake or caldera-lake, for example Santorini, where the phreatomagmatic component of the Minoan eruption was a result of both a lake and later the sea. There have also been examples of interaction between magma a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyroclastic Cones
Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption. Types of volcanic cones include stratocones, spatter cones, tuff cones, and cinder cones. Stratocone Stratocones are large cone-shaped volcanoes made up of lava flows, explosively erupted pyroclastic rocks, and igneous intrusives that are typically centered around a cylindrical vent. Unlike shield volcanoes, they are characterized by a steep profile and periodic, often alternating, explosive eruptions and effusive eruptions. Some have collapsed craters called calderas. The central core of a stratocone is commonly dominated by a central core of intrusive rocks that range from around to over several kilometers in diameter. This central core is surrounded by multiple generations of lava fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcanoes Of Michoacán
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 plates slide p ...

Landforms Of Michoacán
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Volcanoes In Mexico
Types of volcanoes There are multiple types of volcanoes in Mexico. Volcanoes can be of different types such as cinder cone volcanoes, composite volcanoes, shield volcanoes, and lava domes. Each of these variations of volcanos forms in its own way. Cinder cone volcanoes are the simplest type of volcano. This volcano forms from particles of solidified lava that ejected from a single vent. When the lava is eruptive and blows into the air, it separates into small fragments that solidify and fall around the central vent to form an oval cone at the top of the volcano. “Composite volcanoes or stratovolcanoes, make up some of the world’s most memorable mountains: Mount Rainier, Mount Fuji, and Mount Cotopaxi.” These volcanoes are very steep sided and symmetrical, in a cone shape. They have a conduit system which allows the magma to flow from deep within the Earth’s surface. They have many vents within the volcano which allows the lava to break through the walls, which allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purépecha People
The Purépecha (endonym pua, P'urhepecha ) are a group of indigenous people centered in the northwestern region of Michoacán, Mexico, mainly in the area of the cities of Cherán and Pátzcuaro. They are also known by the pejorative "Tarascan", an exonym, applied by outsiders and not one they use for themselves. The Purépecha occupied most of Michoacán but also some of the lower valleys of both Guanajuato and Jalisco. Celaya, Acambaro, Cerano, and Yurirapundaro. Now, the Purépecha live mostly in the highlands of central Michoacán, around Lakes Patzcuaro and Cuitzeo. History Prehispanic history It was one of the major empires of the Pre-Columbian era. The capital city was Tzintzuntzan. Purépecha architecture is noted for step pyramids in the shape of the letter "T". Pre-Columbian Purépecha artisans made feather mosaics that extensively used hummingbird feathers, which were highly regarded as luxury goods throughout the region. During the Pre-Colonial era, the Pur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Puebla, Puebla
Puebla de Zaragoza (; nah, Cuetlaxcoapan), formally Heroica Puebla de Zaragoza, formerly Puebla de los Ángeles during colonial times, or known in English simply as Puebla, is the seat of Puebla Municipality. It is the capital and largest city of the state of Puebla, and the fourth largest city in Mexico, after Mexico City, Monterrey, and Guadalajara. A viceregal era planned city, it is located in the southern part of Central Mexico on the main route between Mexico City and Mexico's main Atlantic port, Veracruz—about east southeast of Mexico City and about west of Veracruz. The city was founded in 1531 in an area called Cuetlaxcoapan, which means "where serpents change their skin", between two of the main indigenous settlements at the time, Tlaxcala and Cholula. This valley was not populated in the 16th century, as in the pre-Hispanic period this area was primarily used for the "flower wars" between a number of populations. Due to its history and architectural styles rang ... [...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 ...
