Photos of East Rift Zone, July 8
The U.S. Geological Survey released these pictures from an overflight taken Sunday morning, July 8, 2018.
Early morning helicopter overflight: no significant change at Fissure 8, channel and ocean entry
Fissure 8 (lower right) and open lava channel leading to the northeast. Geologists noted small lava-level fluctuations in the open channel overnight, which indicates intermittent variations in lava discharge from Fissure 8.
An increase in lava levels was noted about 1.5 hours after the collapse-explosion event at the volcano’s summit at 2:55 a.m. Evidence of a couple of recent, short-lived channel overflows were observed early this morning, but they had not reached the edge of the flow field.
Braided section of the lava channel located “downstream” between about 2.2 to 3.7 miles from Fissure 8 (upper right).
The width of the two channels in the middle center is about 1,065 feet.
View of the partially filled Kapoho Crater (center) and the open lava channel where it makes a 90-degree turn around the crater. The open channel no longer directly enters the ocean.
Clearly, lava moves into and through the molten core of the thick ‘a‘ā flow across a broad area from both the sides and end of the channel.
Lava still oozes from the northern edge of the ‘a‘ā flow near the lighthouse at Cape Kumukahi (upper right).
Smoke from burning vegetation marks location of lava oozeouts.
Multiple ocean entries were active this early morning, each contributing to the prominent “laze” plume above the area.
Lava moves from the open channel through the molten core of the broad ‘a‘ā flow field to the ocean.
