The AA. present the geological and volcanic setting of the Misti volcano which encompasses 2 edifices : the old Misti stratovolcano and the young Misti stratocone. They analyze the stratigraphy and the chronology of its eruptive activity
, in particular over the past 100,000 years : 7 compound groups of deposits record the late Pleistocene eruptive of the modern Misti stratocone. Then, they aim to assess the volcanic hazards of future eruptions at Misti, based on mapping, recent eruptive deposits
, and models used on similar stratovolcanoes : 700,000 people in the Arequipa-Chiguata region are threatened by at least 4 types of volcanic hazards.
