East Pond Vent to the sea

East Pond Vent cone, Pu`u `O`o, Kilauea volcano, Hawai`i
Sloshing lava in pond of East Pond Vent, Pu`u `O`o, Kilauea volcano, Hawai`i
| med | large |
Left. Spatter cone built around East Pond Vent. Pond of lava itself is in crater between the two flanks of the cone. 1312. Right. Splashing and spattering lava pond at East Pond Vent. Escaping gas breaks crust on pond--visible to right of lava--and bursts out as large bubbles that break in the air. Foreground shows fresh spatter on ground from recent larger events than than shown. 1317.
Aerial view of active arm of west branch of PKK flow on coastal flat, Kilauea volcano, Hawai`i
Aerial view of three ocean entries, Kilauea volcano, Hawai`i
| med | large |
Left. Active arm (shiny) of west branch of PKK flow at base of Pulama pali. This arm has broadened substantially in past week. 1507. Right. All three ocean entries are visible in this aerial view looking east-northeast. Largest plume of laze comes from East Lae`apuki entry, where a moderate-size lava delta is growing. Thin bluish plume comes from small entry at East Kamoamoa, just east of point in upper left. Barely visible is a tiny wispy cloud coming from Kamoamoa entry, between East Lae`apuki and East Kamoamoa. Discolored water is visible just off both of the small entries as well as the East Lae`apuki lava delta. 1503.

Lava on the surface

Left. Small breakout in west branch of PKK flow at about the 300-foot elevation above Paliuli. Laze plume rises in distance from East Lae`apuki lava delta. 1002. Right. Lava emerges from small tube in pahoehoe along PKK flow. 1204.

Paliuli and lava inside flow

Aerial view of lava just starting to drop over Paliuli, Kilauea volcano, Hawai`i
Lava in small tube in flow with `a`a crust, Kilauea volcano, Hawai`i
| med | large |
Left. Aerial view of active part of west branch of PKK flow just starting to drop over Paliuli. Incandescence indicates spot where lava is moving over the crest of the pali. Two older, but still young, fingers have reached the base of Paliuli in the past week. Pulama pali is in background. 1248. Right. Lava in tube inside flow with `a`a crust. It is often mistakenly claimed that lava tubes form only in flows with pahoehoe crust. In reality, tubes form in basaltic lava flows before they become either pahoehoe or `a`a, because those terms apply only to solid crust, not liquid lava. 1257

East Lae`apuki and Pu`u `O`o

Aerial view of East Lae`apuki lava delta, showing cracks, Kilauea volcano, Hawai`i
| med | large |
Left. Aerial view looking west of East Lae`apuki lava delta. Smooth surface is most recent lava flows. Note fan of flows reaching onto delta from upper right, the site of the feeding tube. Delta is about 190 m wide perpendicular to shoreline. 0954. Right. Closer and more nearly vertical view of delta, showing linear cracks parallel to shoreline. These cracks did not take part in small collapse on evening of June 27 but could fail at any time. 0954.
New spatter cones forming in East Pond Vent, Pu`u `O`o, Kilauea volcano, Hawai`i
Sloshing lava at MLK vent, Kilauea volcano, Hawai`i
| med | large |
Left. Two vents on floor of East Pond Vent, in crater of Pu`u `O`o. Each vent spatters from time to time. The falling spatter accumulates around the vents to form two new spatter cones. 1134. Right. Aerial view, looking northeast, of pit at MLK vent near southwest base of Pu`u `O`o (upper left). Vigorous sloshing from underneath east wall of pit is building new spatter cone (hidden from view by fume) on crusted floor of the vent. 0944.

Map of flows from Pu`u `O`o: 16 May 2005

Map of lava flows on south coastal part of Kilauea Volcano, May 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 mid May 2005. Yellow shade indicates currently active Kuhio (PKK) flow, active most of the time from March 20, 2004 through present (May 2005). Its large eastern arm feeds the Ka`ili`ili ocean entry. Its western arm once supplied lava to Lae`apuki, but now the west branch of that arm carries lava to the West Highcastle entry. The middle arm of the PKK flow has not amounted to much and hangs high on Pulama pali between the western and eastern arms.

Brown shade denotes MLK flows, which first erupted in January 2004, and, in brief spurts, subsequently.

Red indicates the Mother's Day/Banana flow, which is no longer active. Short flows from the crater, West Gap, and Puka Nui vents are also shown in red. Only the Puka Nui vent is currently producing infrequent, small flows.

New vents opened at the southern base of Pu`u `O`o on January 19, 2004 and fed Martin Luther King (MLK) flows, which remained active until March 5, 2004. Since then, several more vents have formed in the MLK area and continue to erupt intermittently. On March 20, 2004 the Kuhio (PKK) flow originated from two vents, about 250 m south of base of Pu`u `O`o. This flow has been continuously active since July 26, 2004.

The Banana flow developed from breakouts from the Mother's Day lava tube, centered near the former Banana Tree kipuka. The breakouts become prominent in the middle of April and lava started down Pulama pali shortly thereafter. The Banana flow fed an ocean entry from the end of May through the beginning of August. This flow stagnated early in September 2004, and Mother's Day tube died late in 2004.

 

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.
