The Misti is an active volcano (5,822 meters high), located near the southern city of Arequipa. With its ever-covered snow peak, El Misti is Peru's most famous volcano. Located between the volcanoes Chachani (6,075 m) and Pichu Pichu (5,669 m), the Misti is known as the 'gentleman'.
The colonial buildings of the city are built with the volcanic material of the volcano.
The volcano is also known for its symmetrical cone and consists mainly of andesite (outflow rock). It was formed about 12,000 years ago atop a previously erupted Pleistocene volcano. The current caldera measures 1.5 by 2 km.
One of the last major eruptions occurred in the 15th century
