Parasitic cone

Flank volcanoes (also called " adventitious volcanoes " or " Parasitärvulkane " ) are usually smaller volcanic cone, which sit the flanks of a volcano and caused by eccentric outbursts of the main volcano. Flank volcanoes are formed mostly along the so-called eruption columns that are up in the magma chamber reaching fault zones of the earth's crust where the magma can ascend to the surface.

The Europe's biggest volcano, Mount Etna in Sicily, sitting on more than 300 flank volcanoes, typically follow the radially extending from the crater to the northeast and to the south the main fault zones.
