Map of flows from Pu`u `O`o: 19 December 2005

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

Yellow, brown, and red colors indicate lava flows erupted from October 2003 to December 16, 2005. Yellow indicates the currently active Kuhio (PKK) flow, active most of the time from March 20, 2004 to the present. The east and west arms of the PKK flow, once widely separated, began to merge and overlap on the coastal flat in March 2005. The east arm feeds the East Lae`apuki ocean entry. Activity on the west arm declined through mid-August, and the last surface flow on that arm was observed on August 21. The recent (November-December 2005) breakouts on Pulama pali described as "eastern" and "western" are all on the east arm of the PKK flow.

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 continue to erupt intermittently.

Red indicates the Mother's Day and Banana flows, 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.
