Updated Noon - Wednesday, August 1, 2018
USGS Lavaca to NE of PGV lost to fire damage; CORRECTION new cam will take a long time.

Fissure 8 continues feeding a perched channel to Kapoho 8 miles away. Some crusting is seen within cinder cone that is being recirculated like the surface at Halema'uma' lava lake used to. Strombolian explosions still occasionally occurring and tossing spatter above cone on SW side at times. Surges are occurring 1-2 hrs following summit collapse events. Along with surges, pulses cause channel levels to vary. Lava depth along the channel varies. The upper channel runs deeper than braids by Noni Farms above coastal lava pooling W of Kapoho Crater. Channel above and below Green Mountain (Kapoho Crater) is unstable (changeable) & prone to overflowing, overplaying, with sections of narrowing, crusting and ponding. Pond above Grn Mnt is mainly to the N side of the main flow and crusted as are sections of the upper channel. Emissions high, massive plume.

COASTAL FLOW FIELDS: N to S ~4+ miles. The main lava channel is open where it wraps W around Green Mountain. From there the main channel is crusted, swings SE to Kalea (Ahalanui area). Lava also moving beneath the flow field crust, feeding minor Kapoho ocean entry and a westward coastal flow field front just SE of Green Mountain. Flow field stalled N, slow/stalled S; minor W ooze out SE of Kapoho Crater. Pohoiki flow field stalled 150 yds from boat ramp & inside park where boat park. It has glowing spots indicating it is being fed by fresh lava beneath the crust and may begin expansion. Pohoiki area flows ~15 ft deep.

OCEAN ENTRY: Lava delta N - S is ~4 miles with a large laze plume. Delta's N margin stalled. The main channel is entering the ocean in multiple fingers along S margin at Warm Ponds area (Kalea) with a broad ocean entry front over a mile long extending S and slightly N. From Kalea (Ahalanui area) growing delta extends ~150+ yds. Lava is still reaching the Pohoiki delta where Shacks/Bowls were. The Pohoiki ocean entries still 1/10th mi NE from bay and boat ramp. Delta at Shacks/Bowls extends ~500+ yds E (seaward) from where the washed out road was and slowly/stalled S, minor expansion N. Kapoho Bay has a minor entry. At Kapoho Bay several flow lobes have advanced underwater from delta ~1/4+ mile seaward to depths of ~328+ft but delta appears stalled.

VOLCANO SUMMIT AREA: Heightened seismicity & collapse events due to inward slumping of Halemaʻumaʻu rim & walls from summit subsidence continues. Hwy 11 thru Park reduced speed. Crews are using ground-penetrating radar to assess the tarmac roadbed. Crews back & Hwy 11 one lane. Driving is vigilant for damages in roads, stay on pavement. After EQ check utility connections.
