Lava at Ka`ili`ili
|
Lava cascades over seacliff to enter the water at Ka`ili`ili, about
1 km west of Waha`ula. Entry is fed by east arm of PKK flow. |

Near Pu`u `O`o
|
|
| Left. Looking onto cones at MLK
vent area from south flank of Pu`u `O`o. 1052. Right. West
side of Pu`u `O`o, showing West Gap and the two cones silhouetted in
front of it. The black lava flows from the West Gap shield and were
erupted from the cones. 1401. |

Spatter cones and `a`a flows
|
|
| Left. Westward view into Pu`u
`O`o's crater, showing spatter cones that have grown during past
month. East Pond Vent is the nearest cluster of cones. Beehive is
farthest visible cone, standing tall. Cone at Drainhole, partly
silhouetted by fume, is visible between Beehive and East Pond Vent.
West Gap is wide notch in crater rim in background; fume hides the
cones there. 0834. Right. Closer view of cones. The two
nearest camera are at East Pond Vent. High cone with incandescent
top just right of center is at January Vent. Broad fuming
ridge above and right of January Vent is South Wall Complex. Small
cone just right of the complex is at Drainhole. Puka Nui Gap in
upper right. 0833. |
|
|
| Left. Cones at East Pond Vent.
Highest cone is 8-10 m high. These two cones are now visible from
Mountain View. 0839. Right. Cone cluster in MLK vent area at
south base of Pu`u `O`o. Cones are 5-8 m high. 1219. |
|
|
| Left. Two streams of lava in
east branch of PKK flow at mid-level on Pulama pali. Each stream
solidifies to `a`a, which forms levees and high flow fronts. 0848. Right.
Side view of lava streams in left image. 0856. |

West Highcastle ocean entry and feeding lobe
|
|
| Left. Small stream of lava--one
of only two today--flowing from front of West Highcastle delta into
the sea. 0713. Right. Small breakout from inflating PKK flow
feeding West Highcastle delta. Width of active lava, about 50 cm.

New ocean entry at East Lae`apuki
|
|
| Left. "Abandon hope, all ye who
enter here." Those immortal words that Dante put at the gates of
Hell in his poem, Inferno, are apt for this view. Glow reflects from
the walls of a crack into which lava pours at East Lae`apuki. Sea
cliff is at edge of shelf beyond glow. If anyone entered this crack,
hope would be abandoned ...quickly. 0559. Right. Another
entrance which well might bear Dante's inscription. Lava here is
pouring down sea cliff into water (out of view), with glow reflected
from steam and from end of crack in left image. 0604. |
|
|
| Left. Top of lava falls at East
Lae`apuki ocean entry. Looking west, with slopes of Pulama pali in
background. 0643. Right. Lava falls down sea cliff at East
Lae`apuki. Height of cliff, about 12 m. 0641. |
|
|
| Left. Base of lava falls in
images above. 0633. Right. Another view of base of lava
falls. 0638. |
|
|
| Left. Falling arrows of lava.
0647. Right. Trickle of lava builds puddle below,
temporarily out of harm's way from the surf. 0648. |
|
|
| Left. Shadow halfway up sea
cliff gives two-tone appearance to early alpen glow shortly after
dawn. 0654. Right. Sluggish lava trying to resist gravity
and failing. 0656. |
|
|
| Left. The trickles of lava are
slowing as flux lessens and crust grows to hide the liquid. 0701. Right.
Alpen glow shadows give depth to image, which shows how crusted
drapery hangs out away from sea cliff. This happened because the
cliff was slightly overhung, so that the falling lava cooled and
developed crust completely around it. Such drapery is exceptionally
fragile and probably won't last long. 0711. |
|
|
| Left. Small, no, tiny, lava
delta forming at foot of sea cliff gives off plume of laze, mostly
steam. 0726. Right. Wide view of East Lae`apuki ocean entry
and the shoreline southwest of it. Holei Pali in distance.
Photographers' shadows as in Plato's cave. 0709. |

Four views of Pu`u `O`o from Pu`u Huluhulu
|
|
| Left. Early postdawn view of
Pu`u `O`o from top of Pu`u Huluhulu, an old, large spatter cone 10
km west-southwest of Pu`u `O`o. Several incandescent vents are
visible in Pu`u `O`o's crater. Three incandescent vents are outside
the crater in the Puka Nui-MLK vent area. 0613. Right.
Profile of Pu`u `O`o better shown in this image, taken 5 minutes
after the first. The incandescent PKK vent is also visible, to far
right well south of Pu`u `O`o. 0618. |
|
|
| Left. A little color in the
sunrise only two minutes later. 0620. Right. Murk is
starting to build, but most vents and their spatter cones on Pu`u
`O`o are still visible. 0625. |

East side of East Lae`apuki ocean entry
|
|
| Left. East Lae`apuki ocean
entry, with faint glow from West Highcastle entry in distance. Large
view shows headlights of car on Holei Pali, near skyline directly
above new delta. The two growing East Lae`apuki lava deltas are
visible. The nearest is the the largest and oldest; it began on
February 20. The other, smaller, delta appears as a far lobe of the
near delta and probably will become so with continued growth. See
right image for scale. 0629. Right. Tighter view of
East Lae`apuki lava delta, with photographer standing on top of sea
cliff for scale. Note the fan that is building outward from the sea
cliff, down which the two-channeled flow is moving. Contrast these
two images with the last ones posted below on February 21 to see
growth of lava delta; all four images were taken from nearly the
same place. 0634. |

Pu`u `O`o to the ocean
|
|
| Left. Three spatter cones at
June 25 vent, with south flank of Pu`u `O`o in foreground. Middle
cone is spitting Pele's Tears, visible in large image. 1252. Right.
Margin of lava stream in east branch of PKK flow on Pulama pali.
This flow has a crust of `a`a but a relatively fluid interior. Width
of view, about 8 m. 1015. |
|
|
| Left. Aerial view of East
Lae`apuki ocean entry. The two small deltas forming on February 23
have merged to form one small delta. A couple of lava trickles are
visible on sea cliff in large view. Height of cliff, 12-15 m. 0844. Right.
Three plumes of laze, mainly steam but containing dilute
hydrochloric acid and tiny bits of glass, rise from front of
Ka`ili`ili lava delta. This entry was the most active today. 0845. |
|
|
| Left. Lava pours into the sea
off the front and side of the eastern delta of the East Lae`apuki
ocean entry. 0636. Right. Large view of right lava stream in
left image. 0637. Both images taken from same places as the two
images above. |
|
|
| Left. Looking down onto east
delta from top of sea cliff just east of main cascades. Right image
gives context. This double stream is the one shown in first two
images above. 0644. Right. Wider view of east delta, with
West Highcastle (laze plume visible) and points beyond in
background. 0645. |
|
|
| Left. Nearly full Snow Moon
above east delta at East Lae`apuki in predawn darkness. 0605. Right.
Moon is starting to disappear over horizon, and dawn is coming on.

Map of flows from Pu`u `O`o: 2 February 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 early February 2005. Yellow shade indicates
currently active Kuhio (PKK) flow, active most of the time from March 20, 2004 through
present (February 1, 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 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.
