Rift Zone

A rift zone is an elongate system of crustal fractures associated with an area that has undergone extension (ground has spread apart). On the great shield volcanoes in Hawaii, a rift zone consists of many different features associated with the rise and eruption of magma from narrow dikes, including eruptive fissures, cinder and spatter cones, spatter ramparts, pit craters, lava flows, ground cracks, and normal faults.
