Mocho-Choshuenco (Pronounced: ) is a glacier covered compound stratovolcano in the Andes of Los Ríos Region, Chile. It is made of the twin volcanoes Choshuenco in the northwest and the Mocho in the southeast. The highest parts of the volcano are part of the Mocho-Choshuenco National Reserve while the eastern slopes are partly inside the Huilo-Huilo Natural Reserve. Choshuenco, located on the northwest rim of the 4 km wide caldera, is of late glacial age. It has a heavily eroded crater and is currently dormant. Mocho is an andesitic-dacitic volcano placed above the caldera.〔 Some parasitic craters and cinder cones are located on the southwest and northeast flanks of the stratovolcano. Mocho has its earliest certainly recorded eruption in 1759, older eruptions reported are uncertain due to the usage of different names and inexact maps. The northern foothills of Mocho-Choshuenco are surrounded by an arc of rivers and lakes formed by Fui, Enco and Llanquihue River, and Pirihueico, Panguipulli and Riñihue Lakes. The Fui River has high degree of underground infiltration, such that in some years the Huilo-Huilo Falls may dry out completely. As consequence of this infiltration a large aquifer〔(Cuenca del río Valdivia )〕 is situated beneath Mocho-Choshuenco. The southern and eastern slopes drain to Pillanleufú River which flows south along the Liquiñe-Ofqui Fault to Maihue Lake. ==Name== The two volcanoes have had several historical names such as Valdivia, used by Juan Ignacio Molina in 1795, and Panguipulli and Lajara, which Pedro Amadeo Pissis identified in 1875 as Choshuenco and Mocho respectively because only Choshuenco is visible from Panguipulli Lake. Other historical spellings and names for the volcanoes include Choshuenco-Pillán, Rauco, Penguipulli, Reñihue and Riñihue.〔(Volcán Mocho-Choshuenco )〕〔 The current name for the volcano is composed the by the Spanish word ''mocho'' and the native Mapudungun word ''choshuenco'' (pronounced ''choswenko''). ''Mocho'' means short cut and refers to the headless or edgeless shape of Mocho's volcanic cone. The word ''choshuenco'' may be a corruption of the ''chodhuen'' and ''co'' which means yellow earth and water respectively. Another possible etymology is ''chod-hue'' and ''co'' which would mean place where there is water to dye yellow.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mocho-Choshuenco」の詳細全文を読む スポンサード リンク
