Auquihuato
Mountain in Peru
From Wikipedia, the free encyclopedia
Auquihuato[1][2] (possibly from Quechua, awki: prince, watu: prediction, fortuneteller)[3][4] is a cinder cone in the Andes of Peru, 4,980 metres (16,339 ft) high.[1] It is situated in the Ayacucho Region, Paucar del Sara Sara Province, on the border of the districts Colta and Oyolo.[5] Auquihuato lies northeast of Sara Sara volcano.[2]

Geology
Context
Auquihuato is surrounded by a Pliocene volcanic plateau,[6] the cone formed on the plateau's southern margin. Sara Sara lies 30 kilometres (19 mi) southwest,[1] and Firura lies 10 kilometres (6.2 mi) farther east. Auquihuato lies east of the main volcanic arc and is aligned with several other volcanic centres in a northwest-southeast line.[7]
Volcano
Auquihuato is c. 400 metres (1,300 ft) high and a lava flow extends southward from the cone, reaching a length of 12 kilometres (7.5 mi). The lava flow has a pahoehoe texture[6] and a thickness of 50 metres (160 ft).[8] It has well developed levees.[1]
Activity
The stratovolcano developed during the Pleistocene and Holocene.[8] The noticeable lava flow is of Holocene age[6] but no radiometric dating is available[6] and no historical eruptions are known. The Geophysical Institute of Peru began to monitor the geodesy of the system in 2019[8] and it is considered a low-hazard volcano.[9]
Ground deformation has been observed by InSAR observation, centered 7 kilometres (4.3 mi) southeast of Auquihuato and with a circular shape. The ground deformation may be caused by changes in the pressure within the volcano's magma system, at depths probably exceeding 1 kilometre (0.62 mi), but an origin in a hydrothermal system is also possible.[6] Volcano-tectonic earthquakes have been recorded.[8]
