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]
Herðubreið (Icelandic pronunciation: [ˈhɛrðʏˌpreiːθ] ⓘ, broad-shouldered) [3] is a tuya and composite volcano in the northern part of Vatnajökull National Park, Iceland. It is situated in the Highlands of Iceland at the east side of the Ódáðahraun ( [ˈouːˌtauːðaˌr̥œyːn] ) desert and close to Askja volcano.
It is a composite volcano of scoria resting on lava disc and tuff. The area around Mount Porndon is known as the stony rises. The area around Mount Porndon is known as the stony rises. Early settlers used the abundance of rock to build extensive stone fences in the surrounding area.
The Mount Meager massif is the most voluminous composite volcano in the Garibaldi chain and British Columbia, as well as the most recent to erupt. [43] It has a volume of 20 km 3 (4.8 cu mi) and consists of an eroded stratovolcano, ranging in composition from andesite to rhyodacite.
Most of the volcanoes in the Oregon Cascades are either scoria cones, small shield volcanoes, or lava fields, though the segment contains a number of basaltic andesite stratovolcanoes such as Mount McLoughlin. [7] Black Butte is one such stratovolcano [4] (also known as a composite volcano), [9] with a mafic (rich in magnesium and iron ...
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.

Osorno volcano in Chile is an example of a well-developed stratocone.. Stratocones are large cone-shaped volcanoes made up of lava flows, explosively erupted pyroclastic rocks, and igneous intrusives that are typically centered around a cylindrical vent.
