Kilauea

4 January 2001

Shiny new pahoehoe emplaced during the last week extends across the lower end of Royal Gardens subdivision, from Prince Street on the far right past Royal Street at center. The pahoehoe is overriding flows from last spring and summer.

Left: Active `a`a channels course down the steep face of Pulama pali, as seen in this aerial image. The forest on the west (left) side of the flows has been shaved back in the last two weeks by active surface flows on the pali. Most of the lava in this view is less than three weeks old. Right: Pahoehoe toes encroach on a 1985 `a`a flow emplaced during Pu`u `O`o's glory days from 1983 to 1986, when high fountains produced thick `a`a flows.

Sluggish pahoehoe advances into forest above Pulama pali, setting fires at the front of the flow. Most of the lava is crusted over and so is not incandescent. Sunshine reflects off earlier pahoehoe covering the coastal flat in the distance below the pali.

Left: Looking west into the crater of Pu`u `O`o. The heavy fume column rises from vents in the eastern part of the crater. Part of the July 2000 pit--source of recent glow in the crater--can barely be seen along the lower right edge of the fume column. Right: Looking east into the crater through the west gap. The high point on Pu`u `O`o is just hidden by fume in upper right. Nearest fume plume rises from the episode 55 pit and is blown northward by kona wind.

The narrow west flow on coastal flat, shiny in contrast to surrounding older pahoehoe, has moved far seaward in the past week and is now about 800 m from the coast. If it continues, it will reach the sea just west of Kamokuna.

Left: Pahoehoe fed from the 1920-foot breakout point, moving southeastward for some time, has turned south and is moving through forest just west of Royal Gardens subdivision. Smoke in center of image rises from flow front. Pu`u `O`o fumes in upper left, and Mauna Kea rises dimly in upper center. Right: Same flow as in left image, but looking downstream. Coastal flat is in the distance.

Map of lava flows on south coastal part of Kilauea Volcano as of January 2001

Large map Map shows lava flows (red) active from mid-December 2000 through 23 January 2001 above and on Pulama pali and on the coastal plain. Flows re-entered the sea just west of Kamokuna on January 21, 2001. Most of the recent flows are fed from the 1920-foot breakout point, at the northwest tip of the large red area. The east arm of the 1920 breakout is the narrow sliver headed south on the pali. The eastern branch of the main flow points east at the base of the pali, invading lower Royal Gardens. The western branch is the one entering the ocean. Note flows erupted earlier from Pu`u `O`o and Kupaianaha.
