A volcano that is composed of alternating layers of lava and pyroclastic material, along with abundant dikes and sills. Viscous, intermediate lava may flow from a central vent. Example: Mt. Fuji in Japan.

coined in German (von Seebach, 1866), from strato- + volcano. So called for its layered structure.

steep volcano made of hardened lava, rock, and ash. Also known as a composite volcano.

A volcano composed of both lava flows and pyroclastic material. Also called "Composite" volcanoes. Common at convergent boundaries. Excellent examples in the U.S. include Mt. St. Hel [..]

A steep-sided volcano built by lava flows and tephra deposits. (Also called composite volcano.)

a volcano composed of interlayered lava flows and pyroclastic deposits (i.e., erupted rock fragments). They are typically andesite volcanoes, and look like inverted cones (such as Ngauruhoe and Taranaki/Egmont). Also known as a stratocone

A relatively long-lived volcano built up of both lava

A relatively long-lived volcano built up of both lava flows and pyroclastic material.

A volcano with a composite cone, formed by layers of lava and pyroclastics. Most large continental volcanoes are this type. Examples include Mt. Rainier and Mt. St. Helens.

a volcano composed of alternating layers of volcanic ash, lava, and rocks ejected by previous eruptions. Stratovolcanoes are typically steep-sloped and conical.

(vulcanology) A tall conical volcano, composed of layers (or strata) of hardened lava, tephra and ash.
