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]
Mount Katmai (Russian: Катмай) is a large active stratovolcano (composite volcano) on the Alaska Peninsula in southern Alaska, located within Katmai National Park and Preserve. It is about 6.3 miles (10 km) in diameter with a central lake-filled caldera about two by three miles (3.2 by 4.8 km) in size, formed during the Novarupta eruption ...

Block flows, lava flows, lava domes and some ignimbrites of pumiceous composition form this composite volcano. [3] More than six lava domes and two major cones are part of this system and surrounded by a pyroclastic apron, [ 4 ] which covers a surface area of 300 square kilometres (120 sq mi) and is formed from many pyroclastic flows with a ...
