After collapse, which took place piecemeal during the time between 0133 and 0255 this morning. Note rocky debris washed onto delta by waves generated during the collapse. 0944 August 27.
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 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.
Map shows vents, lava flows, and other features near Pu`u `O`o frequently referred to in updates. These features change often, but this map should help those viewers lost in the terminology. The cones in West Gap are just outside the boundary of the crater--the oval-shaped depression containing the seven numbered vents (now down to 6, as Humble Vent has been buried by a mound of lava flows erupted from Dave's Pit/Vent in March. Red color denotes flows--the Mother's Day flows--erupted since May 12, 2002. Light orange color indicates episode-55 flows erupted between March 1997 and August 2002 (exclusive of Mother's Day flows). Darker orange represents MLK flows; yellow, PKK flow; purple, Puka Nui flow. Vents for these sets of flows shown by indicated symbols. Gray shows flows of earlier episodes.
