volcano

Definition of volcano in English English dictionary: A vent or fissure on the surface of a planet (usually in a mountainous form) with a magma chamber attached to the mantle of a planet or moon, periodically erupting forth lava and volcanic gases onto the surface; A vent in the Earth's crust caused by molten rock coming to the surface and being ejected, sometimes violently; (Vol-cane-oh) n an opening in the earth's crust through which molten rock, ash, and gases are ejected; is a naturally occurring vent or fissure at Earth's surface through which erupt molten, solid, and gaseous materials Volcanic eruptions inject large quantities of dust, gas, and aerosols into the atmosphere and can thus cause temporary climatic cooling; a fissure in the earth's crust (or in the surface of some other planet) through which molten lava and gases erupt; The solid structure created when lava, gases, and hot particles escape to the Earth's surface through vents Volcanoes are usually conical A volcano is "active" when it is erupting or has erupted recently Volcanoes that have not erupted recently but are considered likely to erupt in the future are said to be "dormant " A volcano that has not erupted for a long time and is not expected to erupt in the future is "extinct "; A volcano is a mountain from which hot melted rock, gas, steam, and ash from inside the earth sometimes burst. The volcano erupted last year killing about 600 people. volcanoes volcanos a mountain with a large hole at the top, through which lava (=very hot liquid rock) is sometimes forced out. Vent in the crust of the Earth from which molten rock, debris, and steam issue. Volcanoes are commonly divided into two broad types. Fissure volcanoes occur along fractures in the crust and may extend for many miles; lava is ejected relatively quietly and continuously and forms enormous plains or plateaus of volcanic rock. Central volcanoes have a single vertical lava pipe and tend to develop a conical profile; lava flows from the throat and follows the easiest path downhill. Often in these volcanoes highly viscous lava clogs the throat, causing a pressure buildup that is relieved only by violent explosion and eruption. Such eruptions may completely remove the top of the cone and occasionally also part of its interior.

Volcano Islands: Group of three small volcanic islands, western Pacific Ocean, southern of Bonin Islands, Japan. After they were visited by Japanese fishermen and sulfur miners in 1887, the three islands of Kita Iwo, Iwo Jima (the largest), and Minami Iwo were claimed by Japan in 1891. After World War II, Japan retained residual sovereignty over the islands, but the U.S. administered them from 1951 until their return to Japan in 1968
volcano islands: a group of Japanese Islands in the northwesternern Pacific Ocean north of the Marianas
active volcano: A volcano that currently vents lava or gases etc, or has the capability of doing so
dormant volcano: A volcano that has not erupted for a considerable length of time, but is still capable of erupting
extinct volcano: A volcano that is thought to be incapable of further eruptions
mud volcano: A conical structure formed by the eruption of rock fragments and wet mud along with hot gases
shield volcano: A large volcano, with shallow-sloping sides and a flattened dome, formed of successive eruptions of free-flowing lava; a lava dome

Mayon Volcano: or Mount Mayon Active volcano, southeastern Luzon, Philippines. One of the world's most perfect volcanic cones, it has a base 80 mi (130 km) in circumference and rises to 7,943 ft (2,421 m). It is popular with climbers and campers and is the centre of Mayon Volcano National Park, which occupies 21 sq mi (55 sq km). It has erupted more than 30 times since 1616; an eruption in 1993 killed 75 people. Its most destructive eruption was in 1814, when the town of Cagsawa was buried

It is flanked by Chachani and Pichupichu volcanoes and rises to 19,098 ft (5,821 m) above sea level, towering over the city of Arequipa. Its pristine snowcapped cone is thought to have had religious significance for the Incas, and it has inspired legends and poetry. Now dormant, it last erupted during an earthquake in 1600
Sunset Crater Volcano National Monument: Preserve, north-central Arizona, U.S. Established in 1930, the monument covers 5 sq mi (13 sq km) and contains the brilliant-hued cinder cone of an extinct volcano that erupted 1064.
