Map of flows from Pu`u `O`o: 25 July 2005

Map shows lava flows erupted during 1983-present activity of Pu`u `O`o and Kupaianaha (see large map).

Yellow, brown, and red colors indicate lava flows erupted from October 2003 to July 2005. Yellow shade indicates currently active Kuhio (PKK) flow, active most of the time from March 20, 2004 through the present (late July 2005). The east and west branches (arms) of the PKK flow, once widely separated, began to merge and overlap on coastal flat in March 2005. The east branch feeds the East Kamoamoa ocean entry and probably the East Lae`apuki entry as well. The west branch remains active, with intermittent breakouts on Pulama pali.

The brown shade denotes Martin Luther King (MLK ) flows, which first erupted in January 2004 from flank vents on the south slope of Pu`u `O`o. Since then, several more vents have formed in the MLK area, and they ontinue to erupt intermittently.

Red indicates the Mother's Day/Banana flow, which was last active in September 2004. Short flows from the crater, West Gap, and Puka Nui vents are also shown in red. In recent months, only the Puka Nui vent has produced infrequent, small flows.
