Volcanic Field

A volcanic field is an area of Earth crust prone to localized volcanic activity, typically made up of a cluster of as many as around a hundred individual volcanoes, often cinder cones, that share a common source of magma, along with lava flows in some cases. A field may be monogenetic, meaning each volcano within it erupts only once before a new one forms elsewhere in the field, or polygenetic, meaning individual volcanoes can erupt repeatedly. Geologists have not settled on a strict definition of how many volcanoes or what spatial arrangement is required for an area to count as a volcanic field, so the term is applied somewhat flexibly across different volcanic regions.
