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, satellitic cone or lateral cone) is the cone-shaped accumulation of volcanic material not part of the central vent of a volcano.
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 ...
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]
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 Flourmill Volcanoes, also known as The Flourmills, are a small volcano range near the west boundary of Wells Gray Provincial Park in east-central British Columbia, Canada. Located north of Mahood Lake and west of the Clearwater River , they form part of the Wells Gray-Clearwater volcanic field .
A cinder cone (or scoria cone [1]) is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. [ 2 ] [ 3 ] The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent.
A monogenetic volcanic field is a type of volcanic field consisting of a group of small monogenetic volcanoes, each of which erupts only once, as opposed to polygenetic volcanoes, which erupt repeatedly over a period of time. The small monogenetic volcanoes of these fields are the most common subaerial volcanic landform.
