Calbuco is a stratovolcano in southern Chile, located southeast of Llanquihue Lake and northwest of Chapo Lake, in the Los Lagos Region. In topography a summit is a point on a surface which is higher in Elevation than all points immediately adjacent to The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International A foot (plural feet or foot; symbol or abbreviation ft or sometimes &prime – the prime symbol) is a non-SI unit Chile, officially the Republic of Chile ( Spanish:) is a country in South America occupying a long and narrow Coastal strip wedged between the A mountain range is a chain of Mountains bordered by highlands or separated from other mountains by passes or valleys The Andes form the world's longest exposed Mountain range. They lie as a continuous chain of highland along the western coast of South America. A geographic coordinate system enables every location on the Earth to be specified in three coordinates using mainly a spherical coordinate system. Mountains can be characterized in several ways Some mountains are Volcanoes and can be characterized by the type of lava and eruptive history A stratovolcano, also called a composite volcano is a tall conical Volcano composed of many layers of hardened Lava, Tephra, and Volcanic The geologic time scale is a chronologic schema (or idealized Model) relating Stratigraphy to time that is used by Geologists and other The Pleistocene ('plaɪstəsin is the epoch from 18 million to 10000 years BP covering the world's recent period Plate tectonics and hotspots Divergent plate boundaries At the Year 1972 ( MCMLXXII) was a Leap year starting on Saturday (link will display full calendar of the Gregorian calendar.

Geography and demography The region has an area of 67013 km² and its population according to the 2002 INE Census was 1073135 with a population density The volcano and the surrounding area are protected within Llanquihue National Reserve. It is a very explosive andesite volcano that underwent edifice collapse in the late Pleistocene, producing a volcanic debris avalanche that reached the lake.

Calbuco has had at least 9 eruptions since 1837, with the latest one in 1972. One of the largest historical eruptions in southern Chile took place there in 1893-1894. Violent eruptions ejected 30-cm bombs to distances of 8 km from the crater, accompanied by voluminous hot lahars. A lahar is a type of Mudflow / Landslide composed of Pyroclastic material and Water that flows down from a Volcano, typically Strong explosions occurred in April 1917, and a lava dome formed in the crater accompanied by hot lahars. In Volcanology, a lava dome or plug dome is a roughly circular Mound -shaped protrusion resulting from the slow eruption of Felsic Lava Another short explosive eruption in January 1929 also included an apparent pyroclastic flow and a lava flow. A pyroclastic flow (also known as a pyroclastic density current) is a common and devastating result of some volcanic eruptions. Lava is molten rock expelled by a Volcano during an eruption When first expelled from a volcanic vent it is a Liquid at Temperatures The last major eruption of Calbuco, in 1961, sent ash columns 12-15 km high and produced plumes that dispersed mainly to the SE and two lava flows were also emitted. There was a minor, 4-hour eruption on August 26, 1972. Strong fumarolic emission from the main crater was observed on August 12, 1996.
