Highcastle lobe and broken bench

Destruction of eastern part of Highcastle bench, resulting from sudden collapse on morning of August 18. Images taken from same place. Left. August 14. Right. August 19.

Highcastle lobe bears down on small kipuka of Chain of Craters Road--the only such kipuka remaining between Wilipe`a and Kapa`ahu. Left. This tongue lapped against roadway (foreground) but had stalled at 0545.  Right. At 0615:47, photographers look at place where lava gushed out 7 minutes earlier. Gush is shown in following seven images.

Gushing breakout starting at 0608:10 from upper center of image.

0608:33. Breakout now has two or three sources.

0608:41. Crust between separate sources is tearing away as lava pours from inflated flow.

0608:49. Disrupted crust is being torn apart, but leading edge of breakout is starting to cool noticeably.

0609:00. Crust is now in two pieces, and surface of cooling lava itself is being torn (left side).

0609:20. Breakout is past its prime, and crust forms on most of lava. Tattered older crust hangs in there.

Steps leading down from Chain of Craters Road to visitor overlook at Highcastle. Stone wall above borders roadway. Left. Narrow flow wormed its way down several steps yesterday, stopping as supply of lava ended. Right. Head-on view of the tiny stair-climber.
Lava spills down and along Highcastle stairs at 0842, Kilauea volcano, Hawai`i

0842. Something there is that doesn't love a stairway. Lava this morning again used the stairs for awhile but then took a faster route alongside. Note flowing lava in upper right of large view. This flow hadn't started down the embankment at 0630. It is well on its way to the top of the sea cliff only several meters away.

Stone wall at visitor overlook below stairs at Highcastle kept lava from pouring over sea cliff yesterday. Flow inflated against wall and would have overtopped it if supply continued.

Early morning at Highcastle Stairs

Spigots of lava off front of Highcastle Stairs bench, Kilauea volcano, Hawai`i
| med | large |

Spigots are turned on, and lava pours into ocean off front of Highcastle Stairs bench. Each spigot is mouth of small lava tube within bench. See images below for location. 0525.

Two early dawn views of Highcastle Stairs bench, viewed from west. Two main falls carry lava onto bench, where most sinks beneath crust. Spigots at seaward edge of bench are places where lava spills from interior of bench. Left. Entire bench at 0538. Right. Front of bench and wave lit by glow at 0539. Coastline heads for Lae`apuki, site of entry in late 1999-early 2000.

Left. Highcastle Stairs bench at daybreak at 0558, viewed from west. Compare with image directly above. Note decreased surface activity in only 20 minutes; such waxing and waning is typical of most benches. Right. Highcastle Stairs bench viewed from east at 0608. Note lava pouring from bench into water, not visible from west. For scale, figures on top of sea cliff are barely visible behind steam cloud in large view.

Top of eastern lava cascade sending lava onto bench. Same falls as in image on right above. 0617. Black sand beach just west of bench dates from time of Lae`apuki entry farther east in 1999-2000.

Eastern part of Highcastle bench continues to be modified by collapse and erosion. Much was removed by collapse on August 18 (see images below on August 19). Later minor collapse, and wave erosion, reduced beach still farther, as these images, taken from same place, show. Left. August 19. Right. August 22.

| med | large |
Left. Looking west along coast. Broad Highcastle lobe (center and upper left) has three obvious benches. Largest is Highcastle Stairs (left center), with western part of Highcastle bench and nearby Visitor Entry "bench" (actually a flow on a black sand beach, not a true bench) along coast to left. West Highcastle lobe is across black 1995 flows and forms bench near left side of image, at far end of larger, darker 1995 bench. Across another kipuka of 1995 flows is Wilipe`a lobe, with pavement of Chain of Craters Road in extreme upper left. Right. Head-on view of Highcastle lobe and its three ocean entries (shiny areas below sea cliff), from left to right, Visitor Entry "bench," western part of Highcastle bench, and Highcastle Stairs bench. Eastern part of Highcastle bench, at and just east of small point, collapsed and eroded away on August 18-20. Small kipuka of 1995 flow just inland of west end of Highcastle Stairs bench is along buried Chain of Craters Road. In background is Paliuli (mostly in cloud shadow) with shiny, active lobes of Mother's Day flow visible along west and east sides of flow just above pali. West lobe fed lava Niagara earlier in day shown in image below.

A series of cascades about 125 m wide pours down Paliuli at 0429. Howling wind shook tripod to blur  image. Feeding flow visible on slope to left above Paliuli. Viewed from end of pavement on Chain of Craters Road.

Right. Same breakout as that to left, showing its advance along and beneath crust of older inflated flow forming high tumulus. 0638.
