Sabancaya VulkanSchichtvulkan 5967 m / 19,577 ft
Peru, -15.78°S / -71.85°W Aktueller Status: nicht aktiv (1 von 5)
Typische Aktivität: explosive and effusive
Ausbrüche des Sabancaya: 2003, 2000, 1998, 1997, 1990-95, 1988, 1986, 1784, 1750, <1595(?) The stratovolcano is covered with several glaciers and located in the saddle between the older stratovolcanoes Ampato (6288 m) and Hualca Hualca (6025 m) and the only one of the group that has erupted in historic times. Sabancaya belongs to one of South America's volcanoes with the oldest recorded history of eruptions. Historic records of eruptions from Sabancaya date back to 1750, but its name already appears in written accounts from 1595 AD, suggesting that it had been active around or before that date as well. Beschreibung:Both Nevado Ampato and Nevado Sabancaya show only little erosion due to glacial cover, suggesting that much of their summit edifices are geologically young.Activity within the past 10,000 years consisted of explosive plinian eruptions followed by effusive eruptions of voluminous andesitic and dacitic lava flows. These flows surround the volcano on all sides except the north flank. |
