Ubinas

About Ubinas in brief

Ubinas is an active stratovolcano in the Moquegua Region of southern Peru. It rises 5,672 metres above sea level and is part of the Central Volcanic Zone of the Andes. The volcano’s summit is cut by a 1.4-kilometre-wide and 150-metre-deep caldera, which itself contains a smaller crater. Below the summit, Ubinas has the shape of an upwards-steepening cone with a prominent notch on the southern side. The gently sloping lower part is also known as U binas I and the steeper upper part as UbinAs II. The name Ubin as means “to stuff” or “to fill” in Quechua. In Aymara, hupi means “murmur” and hupina is the genitive of “hupi” The volcano is monitored by the Peruvian geological service INGEMMET, which has published a volcano hazard map and regular volcanic activity reports. It has a history of small to moderate explosive eruptions as well as a few larger eruptions, such as in 1667, along with persistent degassing and ash emissions. Among the recent eruptions was the 2006–2007 event, which produced eruption columns and led to ash fall in the region, resulting in health issues and evacuations. During the most recent activity, from 2013 to 2017, a lava flow formed inside the crater, and further ash falls led to renewed evacuations of surrounding towns.

Glacial valleys at the foot of the volcano indicate that glaciers developed on the region during the last glacial maximum. Other volcanic cones all show signs of heavy erosion by heavy glaciation by glaciation. The volcanoes Ampato, Casiri, Chachani, Coropuna, and Sara Sara are dormant. Four lava domes cover the terrain north and east of U Binas, and some lava flows and some ash flows cover the ground around the volcano. Four out of the seven volcanoes are related to the volcano and may be related to crop crop and crop-growing activities around it. The most active volcanoes in Peru are El Misti, Huaynaputina, Sabancaya, Ticsani, Tutupaca, and Yucamane. Peruvian volcanoes include Stratovolcanoes, which are typically active for less than 500,000 years, long-lived clusters of lava dome, and monogenetic volcanic fields. The Central Volcanoic Zone is 1,500 kilometres long, and 69 of its volcanoes have been active in the Holocene epoch. It is one of four volcanic belts in theAndes; the others are the Northern VolCANic Zone, the Southern Volcanics Zone, and the Austral VolcanIC Zone. The Volcano is located in the General Sánchez Cerro Province, MoquEGua Region, 60 kilometres east of Arequipa in the Per Peru Western Cordillera.
