Kohola ocean entry is on its way
|

|
Left. General view of new Kohola ocean
entry, looking east from Ka Lae`apuki, of cascades and new flow coating
beach. Sea cliff is about 10 m high. Wispy glow near center right edge is
from steam at water's edge. 0533. Right. Easternmost stream
falls to base of sea cliff, forming incandescent talus cone. Sea cliff is
illuminated by the freely falling lava. 0540. |
|

|
Left. Steam generated by entry of lava
into water reflects incandescence and appears reddish. 0548. Right.
View at daybreak of Kohola entry and, in center, laze plume at West
Highcastle, 1.8 km away. 0627. |
|

|
Left. Breakout within flow feeding
Kohola entry, steam from which rises above sea cliff in upper left. 0642. Right.

Lava at Kohola ocean entry
|

|
Left. Rosy view of some cascades and
lava flow on beach at Kohola ocean entry. Photo taken from vantage point
farther west than that used for first image yesterday; that point was near
site of nearest cascade. Width of covered beach is 30-50 m. 0527. Right.
Photo taken from same place as image to left, but in daylight. Photographer
works near point of nearest cascade in left image, which stopped flowing
just after left image was taken. Photographer is at site of most of
yesterday's images. 0635. |
|

|
Left. Most actual ocean entries are taking place at southwest end of covered
beach, as this image shows. 0628. Right. Detail of largest
breakout feeding lava into water (near right of image). Flow is about 7 m
long. 0636. |
|

|
Left. Photographer on top of sea cliff
engrossed in lava cascade while small flow breaks out nearby. Small surface
breakouts are common in this flow above the cliff. 0644. Right.
Detail of flow ignored by photographer. 0645. |
|

|
Left. Cascade down sea cliff, and
channeled flow it feeds across covered beach. This is what photographer in
upper left image was filming. Cascade is 8-10 m high, and channeled flow
reaches 20-30 m out from base of cascade. 0646 Right.
Detail of channeled flow from farther west. 0651. |
|

|
Left. Looking west along sea cliff at
Kohola. Main cascade shown above is prominent. Cascade shown in first image
today has resumed as a lava falls (left of center). Person on top of cliff
gives scale. 0650. Right. East end of Kohola entry, showing lava
flow sneaking eastward across black sand beach. Large image shows
incandescence through steam. Person atop distant cliff gives scale. 0656. |

West end of Kohola ocean entry
|

|
Left. Cascade and lava falls, 8 m
high, over sea cliff at west end of Kohola ocean entry. Soon after this
image was taken, a gush destroyed upper part of cascade, but the wound was
quickly healed and the cascade-falls continued to play for more than 1.5 hr
thereafter. 0523. Right. Lower part of same falls, but one
hour later. Note that drapery and a stalactite-like mass is forming like
candle wax from dribble left of main falls. Note too the fan or pedestal
starting to build at base of falls. 0630. |
|

|
Left. Photographer silhouetted by glow
from lava falls shown above and burned out in this image. 0544. Right.
Gushing lava at top of cascade. Width of upper stream, about 4 m. Lava
gushed out suddenly and fed broad cascade and falls, which, over a few
minutes, settled back down to the size shown above. 0554. |
|

|
Left. Lobe of lava moving along west
edge of flow reached top of sea cliff and began plunging to beach below.
This image was taken several minutes after the falls began. Liquid lava is
2-4 m wide. 0605. Right. Two lava falls at Kohola. Distant is that
shown above. Close is that shown to left. 0621. |
|

|
Left. Bottom of main lava falls,
showing pedestal of crust developed by neighboring falls. Height of falls
shown, about 3 m. 0623. Right. Close-up of base of falls, showing
pedestal and grotto behind. 0642. |
|

|
Left. Photographer shooting main
cascade and falls soon after daybreak. 0641. Right. Looking
northeast along sea cliff, showing main cascade-falls and, through steam in
distance, three other, smaller, cascades (visible best in large image).
Small lava delta forms rightmost point below cliff. 0644. |

Breakouts on new lava delta
|

|
Left. Breakout on gentle surface of
Kohola lava delta, near its western end, viewed from top of sea cliff.
Ocean is just to right off image. Length of flow, about 7 m. 0553. Right.
Breakout traveling down lava fan created across old sea cliff (right),
slowing, and spreading out on gently sloping surface of central part of
Kohola lava delta. Length of flow, about 20 m. 0626. |

Two views of breakout above Chain of Craters Road
|

|
Left. Lava is flowing out of tumulus
that photographer stands on. Lava was apparently stored in tumulus before
breaking out suddenly. People on tumulus could feel it cracking and
shifting as it drained. Location is about 950 m above Chain of Craters Road
along west margin of Kohola flow. Right. View upstream of slowing
breakout, moving from under its own crust. |
25 February 2003
Lava toes 175 m above Chain of Craters Road
|

|
Left. As saggy as sea lions flaked out
on a beach, elongate toes of lava ooze from Kohola flow and enjoy sunrise.
Width of view, about 6 m. 0627. Right. More elongate toes on gentle
slope of breakout. Width of view, about 6 m. 0630. |
|

|
Left. Small breakouts move away from
tumulus in old flow. Note fire in bushy tree on tumulus. Same set of lava
toes as in images above. 0633. Right. Near view of flat toe moving
across quite flat surface. Note that lava at moving front of toe is
emerging from base and cooling as it rises. Flaming grass at front of
another toe. Width of view, about 2 m. 0640. |
|

|
Left. Spreading crust atop toe shown
in right image above. Spreading is toward lower right, as shown by shape of
wrinkles, and is pulling folded crust away from "stable" crust along
incandescent zone. Width of view, about 1 m. 0640. Right. Moving
lava toe split by, and now enveloping, clump of grass. Note ash from burned
grass on crust of toe. Width of view, about 1.5 m. 0644. |
|

|
Left. Ground-level view of lava oozing
from under crust at front of small toe. Width of view, about 50 cm. 0646. Right.
Two toes of lava meeting at burning grass clump, with small shrub just
catching fire. Width of view, about 1.5 m. 0650. |
28 February 2003
Over the top of a tumulus
|

|
Left. Lava pours down flank of
4-m-high tumulus in old (>600 year) flow. Lava comes from interior of
Kohola flow, which banked against north side of tumulus, inflated over the
top, and now spills down steep south side. Width of view, 6 m. 0523. Right.
Fourteen minutes later, new stream pours from interior of inflated flow
down flank of tumulus. View looks into mouth of inflated flow, partly
evacuated by lava spilling out. Crust on inflated flow can be considered as
roof of partly filled lava tube. Width of stream, about 1 m. 0537. |
18 February 2003
|
February 18, 2003; 0524. Cascade and lava falls
on west edge of Kohola ocean entry, falling over sea cliff about 8 m high.
Turn down your sound; lots of wind noise.
|
|
February 18, 2003; 0549. Part of broad cascade
and falls that suddenly gushed from under crust at top of sea cliff. Turn
down your sound; lots of wind noise.
|
|
February 18, 2003; 0602. Base of lava cascade and
construction of mound on beach below sea cliff. Turn down your sound;
lots of wind noise.

Map of flows from Pu`u `O`o: 17 February 2003

Map shows lava flows erupted during the 1983-present activity of Pu`u `O`o
and Kupaianaha (see
large map). The most recent--and ongoing--activity has produced the lender,
dark red flow along western edge of flow field. This flow entered the sea late
on Valentine's Day to form the Kohola ocean entry. Lava is actively widening the
flow on February 17, and the western arm is nearing the Chain of Craters Road.
Visitors now can drive to Holei Sea Arch, 1.1 km from the Kohola flow, and walk
to see the new flow. The new flow is part of the Mother's Day flow, which began
erupting on May 12, 2002.. Lava from the Mother's Day flow (broad red flow on west side of flow field)
reached the sea at West Highcastle early on July 19, at Wilipe`a early on
July 21, and at Highcastle on August 8. From near the southwest base of Pu`u `O`o, the
Mother's Day flow passes along the west side of the flow field and into the
forest, where it started a large wildfire in May that continued into late July. By June 10,
the Mother's Day flow had reached the base
of Paliuli, the steep slope and cliff below Pulama pali and just above the
coastal flat. At the base of Paliuli, the Mother's Day flow abruptly spread
laterally in a series of small budding flows to cover an area nearly 2 km
wide, gradually moving seaward until the West Highcastle and Wilipe`a lobes
finally reached the ocean and started building benches. Activity at West
Highcastle ended in early August, but entry began soon thereafter at Highcastle,
eventually burying tiny kipuka of the Chain of Craters Road. The Wilipe`a entry
died away slowly and had ended by mid-August. Highcastle and neighboring
Highcastle Stairs entries ended on about August 23. For a time there were no
active entries. Then Wilipe`a was reactivated on September 3 but stopped in
December. West Highcastle likewise renewed its activity on September
16-17, died away during the night of September 18-19, and returned soon
thereafter to continue to time of mapping. East arm of Mother's Day flow
branched from Highcastle lobe in late October and sent three fingers into ocean
at Highcastle on November 15, West Lae`apuki on November 19, and Lae`apuki on
November 20. The Lae`apuki entries had stopped by November 29. If this sounds
like a soap opera, the truth is even more confusing than the simplified version
of activity given here.
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.
