Left. Aerial view looking west across Pu`u `O`o. Six fuming vents are, from front to back, East Pond Vent, January Vent, South Wall Complex, Drainhole, Beehive, and West Gap. 0913. Right. Looking down onto East Kamoamoa lava delta and small entry plume. The delta is 400 m long parallel to shoreline and extends 70 m seaward from old sea cliff. The delta has an area of about 2 ha. 0918.

Left. Aerial view looking southeastward across East Lae`apuki lava delta. Thick laze plumes rise from entry areas along front of delta. Foreground fume comes from skylights in PKK lava tube that feeds the delta. 0919. Right. Lava pouring from tube at eastern front of East Lae`apuki delta. Note small pocket beach, and steaming rocks stranded on the sand. 0927.

Left. Aerial view looking at East Lae`apuki lava delta. Large plume comes from cluster of entry points at apex of delta. These entries are nicely visible from points along Chain of Craters Road farther west. Whiffs of blue fume comes from cracks in roof of lava tube feeding the delta. 0932. Right. Three lava falls near tip of delta. Height of falls, about 3 m. 0955.

Maps of lava-flow field, Kilauea Volcano

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

Map of lava flows on south coastal part of Kilauea Volcano, 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 of Pu`u `O`o and vicinity as of 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.
