Pulama pali continues to fume as tube-fed lava travels below
the surface on the way to the active ocean entry.
|
The skylight at the 270-foot elevation is dark. The lava stream is
blocked and cannot be seen from here.

Above Left: Tube walls in the skylight at the 250-foot elevation are
incandescent, but crust has formed over most of the lava, dimming its
brightness. Above Right: Cracks along the tube system below the 250-foot skylight reveal
incandescence. Left: Cracks along the tube system below the 250-foot skylight display sulfur deposits on the surface and
incandescent lava beneath.

Santa and Surface Flows 11:00 am

One breakout is visible on the coastal plain just below the base of Pulama pali.
A vigorous pahoehoe flow fans out
toward the east, covering a pre-September `a`a flow.

During today's overflight a curious sleigh was seen on the flow field. Upon landing, our scientific
research team discovered that Santa Claus and Merry Christmas were vacationing on the Big Island,
fed up with the endless joking of elves. The team's interview and photos bring two new
findings to light. First, Santa Claus is Hawaiian. Second, he doesn't laugh all the time.
The latter is understandable, considering the rock hammer that Ms. Christmas was wielding.

Left: The flow stagnated
by early evening, 280 m southeast of the
250-foot elevation skylight, at about the 180-foot elevation. It is
2.4 km from the coast and covers 3.9 ha. In
most places the breakout is about 1 m thick. Right: By early
evening no budding lava toes were visible anywhere. The flow ponded
against topographic obstructions along most of its margin. This may have
added to the fairly abrupt change in status from active to completely inactive.

Above Left: The Kamokuna ocean entry has a relatively
large steam plume, mainly coming from closely spaced entry points at the
center of the bench. Another smaller, isolated
plume is at the eastern part of the bench. Above Right:
Two prominent lava-entry points are on the bench. One
is indicated by visible lava near the eastern edge. Left:
The visibility around the crater of Pu`u `O`o is better than usual.

Map of flows from Pu`u `O`o to the ocean; September 2000

Large
map. Map shows lava flows (red) active in September 2000 above and on Pulama
pali and on the coastal
plain, as well as flows erupted earlier from
Pu`u `O`o and Kupaianaha. The
eastern part of the active flow field (orange) extended to the Royal Gardens private
access road on January 11 and entered the sea near Waha`ula on February 3-14,
2000. That flow stopped in mid-August. A new flow (red) descended Pulama
pali
and crossed the coastal plain in
September, and lava is now entering the sea at Kamokuna, an area about 1.5 km
west-southwest of Waha`ula.
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.
