Parasitic cone (in foreground) with larger main cone in background, at Piton de la Fournaise volcano on the island of Réunion. A parasitic cone (also adventive cone, satellite cone or lateral cone) is the cone-shaped accumulation of volcanic material not part of the central vent of a volcano. It forms from eruptions from fractures on the flank ...
A tuff cone, sometimes called an ash cone, is a small monogenetic volcanic cone produced by phreatic (hydrovolcanic) explosions directly associated with magma brought to the surface through a conduit from a deep-seated magma reservoir. They are characterized by high rims that have a maximum relief of 100–800 meters (330–2,620 ft) above the ...
There is no single standard definition for a volcano. It can be defined from individual vents, volcanic edifices or volcanic fields. Interior of ancient volcanoes may have been eroded, creating a new subsurface magma chamber as a separate volcano. Many contemporary volcanoes rise as young parasitic cones from flank vents or at a central crater ...

Oreum (Korean: 오름) refers to the around 360 small rising extinct volcanoes on Jeju Island, in Jeju Province, South Korea. [ 1 ] [ 2 ] They are commonly described as cinder cones or parasitic cones , and are often inside larger volcanic craters.
It is a typical parasitic cone and the mouth of a volcano has a girth of 300m, 40m in depth and 1,000m circumference around the crater. Viewed from the summit of the mountain north of crater, its external shape has a concentric circle and hollowed surface in the middle of crater respectively.
The erupted volcanic material (lava and tephra) that is deposited around the vent is known as a volcanic edifice, typically a volcanic cone or mountain. [ 2 ] [ 22 ] The most common perception of a volcano is of a conical mountain, spewing lava and poisonous gases from a crater at its summit; however, this describes just one of the many types ...
Mount Scott is a small stratovolcano and a so-called parasitic cone on the southeast flank of Crater Lake in southern Oregon. [4] [5] It is approximately 420,000 years old. [3] Its summit is the highest point within Crater Lake National Park, and the tenth highest peak in the Oregon Cascades. [6]
