Cinder Cone

Dictionary.png
Cinder Cone:
Cinder cones, also known as scoria or spatter cones, are a relatively simple type of volcano consisting of a steep conical pile of volcanic ash and tephra. They exhibit a lower profile than stratovolcanoes (usually rising no more than a thousand feet above the surrounding topography), and typically have a bowl-shaped depression at their summits. They form primarily from the eruption of pyroclastic ejecta and are commonly encountered on the flanks of stratovolcanoes, shield volcanoes, and calderas.

Topographic Features

List of topographic features commonly encountered in geothermal resource areas:
Schematic representation of the internal structure of a typical cinder cone.[1]


"Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most cinder cones have a bowl-shaped crater at the summit and rarely rise more than a thousand feet or so above their surroundings. Cinder cones are numerous in western North America as well as throughout other volcanic terrains of the world."[1]
