In the lower East Rift Zone, lava enters the ocean along a broad flow front
Having crusted over about 0.5 miles upchannel from the ocean entry, lava oozes from the flow’s molten interior to enter the sea along a broad flow front on the northern (Kapoho) side of the flow.
Lava enters the sea along the Kapoho coastline, building a delta that is now over 555 acres in size.
Lava builds levees along the channel margins, in Kīlauea Volcano’s lower East Rift Zone
Lava, from small overflows, cools and congeals along the banks of the lava channel to build lava levees.
This image of the lava levee and perched lava channel were taken during the morning helicopter overflight of the lower East Rift Zone, in the vicinity of Luana and Kahukai streets, in the Leilani Estates subdivision. The lava levee is the rampart in the middle of the image with small spillovers and lava crusts visible on the levee walls. The active lava channel is the silver-colored flow with lines of visible incandescence in the upper part of the image.
Flow advances northward near ocean entry

At Four Corners, a low lavafall
Near the Kapoho Crater, in the area called Four Corners, the lava channel makes a 90-degree bend. After lava exits the bend, it makes a short drop to form a lavafall.
A side channel makes a short surface diversion before rejoining the existing channel.
