The June 26 breakout remains active at the flow front, which can be distinguished by the light silver color at the bottom-center of the photo. The flow has been slowly advancing along the eastern margin of the main episode 61g flow field, and this afternoon was approximately 1 km (0.6 miles) from the base of the pali and 2.2 km (1.4 miles) from the emergency access road. The breakout has developed a lava tube on the pali based on the areas of concentrated degassing on the pali (center) and above.
A zoomed in view of the Kamokuna lava delta reveals several crack systems parallel to the sea cliff which suggests instability of the delta. Over the past few weeks, flows on the delta have built up the surface near the base of the cliff creating a slope seaward.
This image shows a comparison of a normal photograph (left) with a thermal image (right) of the lava delta. The cracks spanning the delta, and the warm water plumes extending out from the entry point, are evident in the thermal image. A circular area of discolored water is cool in the thermal image, and may represent a zone of upwelling of deeper water to the surface.
