A long line of lava fountains several tens of meters high rise along a NE-flank fissure of Hawaii's Mauna Loa volcano on March 25, 1984. The fissure-fed eruption began within the Mokuaweoweo summit caldera and on the upper SW flank and then was concentrated on the NE flank. Single discrete segments of the eruptive fissure are offset, forming an en-echelon pattern. Activity commonly migrates along a fissure during the course of an eruption. Cinder cones may form where eruptive activity becomes localized at one or more points.
