Left. White plumes of laze blow seaward  from points along the front of the East Lae`apuki lava delta where lava is entering the water. The shiny part of the delta indicates hot solidified lava that partly fills the collapse scar formed on August 27 (see below). Blue fume comes from a skylight over the lava tube feeding lava into the delta. 0850. Right. Closer view of the collapse scar and the new part of the delta filling in the scar. 0854.

Left. Looking down on East Pond Vent. Roiling pool of lava is about 8 m below lip of vent. 0832. Right. Oblique view across crater of Pu`u `O`o. Nearest crags are relics of spatter cones at East Pond Vent. In distance, cones at January Vent, Drainhole, and Beehive are visible. 0837.

Left. Looking southwest across east end of East Lae`apuki lava delta. Note rocky debris strewn across surface of delta, the product of storm surges during the past week. 0852.  Right. Lava falling from southeastern part of East Lae`apuki delta. Falls are 3-4 m high. 0904.

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.

Map of Pu`u `O`o and vicinity: 24 August 2004

Map shows vents, lava flows, and other features near Pu`u `O`o frequently referred to in updates (see large map). 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.

Eruption-viewing opportunities change constantly, refer to the HVO home page for current information. Those readers planning a visit to Kilauea or Mauna Loa volcanoes can get much useful information from Hawai`i Volcanoes National Park.
