Socompa is a 6,051-metre-high (19,852 ft) [b] [c] [27] composite volcano [4] consisting of a central cone and several lava domes; [28] it is the most voluminous conical volcano of the Central Volcanic Zone [29] and one of the highest edifices there, rising more than 2 kilometres (1.2 mi) above the surrounding terrain.

A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers of hardened lava and tephra. [1] Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions. [2] Some have collapsed summit craters called calderas. [3]
A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. [1] They may form due to changes in eruptive habit or in the location of the principal vent area on a particular volcano. [ 2 ]
Nevado Sajama ([neˈβaðo saˈxama]; Aymara: Chak Xaña) is an extinct volcano and the highest peak in Bolivia. The mountain is located in Sajama Province, in Oruro Department. It is situated in Sajama National Park and is a composite volcano consisting of a stratovolcano on top of several lava domes.
It consists mainly of volcanic rocks that form the largest remnant of a major composite volcanic field that covered most of the southern Rocky Mountains in the Middle Tertiary geologic time. [1] There are approximately fifteen calderas known in the San Juan Volcanic Fields; however, it is possible that there are two or even three more in the ...
Scott was the first of the composite volcanoes that created the Mazama complex, formed by a quick and active cone-building phase and becoming inactive long before the most recent eruption at Mazama. With time, eruptive activity moved to the west, creating the Applegate Peak and Garfield Peak cones on the southern flanks of the volcanic center.
The volcano formed during the Pleistocene epoch, about one million years ago, and since the most recent ice age, it has produced some of the largest and most explosive eruptions in the state. When continental ice sheets retreated from the region, Glacier Peak began to erupt regularly, erupting explosively five times in the past 3,000 years.
