Flank volcano
Flank volcanoes (also known as " adventitious volcanoes " or " parasitic volcanoes " ) are mostly smaller volcanic cones that sit on the flanks of a volcano and are created by eccentric eruptions of the main volcano. Volcanoes edge formed along usually so-called eruption columns that are up in the magma chamber reaching fault zones of the earth's crust on which the magma can ascend to the surface.
The largest volcano in Europe, Mount Etna in Sicily , has more than 300 flank volcanoes, which typically follow the main fault zones that run radially from the crater terrace to the northeast and south.
