Sabancaya

Stratovolkan · Peru · 5960 m

The Sabancaya volcanic complex consists of Sabancaya volcano proper (foreground), the older 6288-m-high Ampato volcano (background), and 6025-m Hualca Hualca volcano. Sabancaya, viewed here from the NE, is constructed on the saddle between the two older volcanoes. It is the youngest of the three Holocene volcanic centers and the only one to have erupted in historical time. An extensive 15-km-wide apron of trachytic and dacitic lava flows surrounds the 5967-m-high volcano. Records of historical eruptions date back to 1750.

Sabancaya, located in the saddle NE of Ampato and SE of Hualca Hualca volcanoes, is the youngest of these volcanic centers and the only one to have erupted in historical time. The oldest of the three, Nevado Hualca Hualca, is of probable late-Pliocene to early Pleistocene age. The name Sabancaya (meaning "tongue of fire" in the Quechua language) first appeared in records in 1595 CE, suggesting activity prior to that date. Holocene activity has consisted of Plinian eruptions followed by emission of voluminous andesitic and dacitic lava flows, which form an extensive apron around the volcano on all sides but the south. Records of observed eruptions date back to 1750 CE.

Ringkasan Wikipedia

Ringkasan Inggris

Sabancaya is an active stratovolcano in the Andes of southern Peru, about 70 kilometres (43 mi) northwest of Arequipa. It is considered part of the Central Volcanic Zone of the Andes, one of the three distinct volcanic belts of the Andes. The Central Volcanic Zone includes a number of volcanoes, some of which, like Huaynaputina, have had large eruptions, and others, such as Sabancaya and Ubinas, have been active in historical time. Sabancaya forms a volcanic complex together with Hualca Hualca to the north and Ampato to the south and has erupted andesite and dacite. It is covered by a small ice cap, which leads to a risk of lahars during eruptions.
