Map shows lava flows erupted during 1983-present activity of Pu`u `O`o

Map shows lava flows erupted during 1983-present activity of Pu`u `O`o and Kupaianaha. Red colors, both dark and light, denote Mother's Day flow, which began erupting on May 12, 2002. Different shades of red indicate different stages of activity of Mother's Day flow. These different stages are still considered part of Mother's Day flow, because they all come from same tube system near base of Pu`u `O`o.
