Pichu Pichu is an inactive eroded volcano in the Andes of Peru, with seven summits; the highest reaches a height of 5,664 metres (18,583 ft). It lies east of the city Arequipa and together with its neighbours Misti and Chachani is part of the Central Volcanic Zone of the Andes. Pichu Pichu was active many millions of years ago, producing ignimbrites and lava flows with andesitic composition. During the last two million years, a gigantic landslide descended the western side of the volcano and left a large scar that runs north to south. Pichu Pichu bore glaciers during the last glacial maximum, which left moraines and other glacial landforms after they retreated.

Arequipa, also known by its nicknames of Ciudad Blanca and León del Sur, is a city in Peru and the capital of the eponymous province and department. It is the seat of the Constitutional Court of Peru and often dubbed the "legal capital of Peru". It is the second most populated city in Peru, after the capital Lima, with an urban population of 1,296,278 inhabitants according to the 2017 national census.
