Overnight views show Fissure 8 lava roiling in the vent and feeding a pulsing channel

The field crew is at a high point overlooking the channel near where it makes a 90 degree turn around Kapoho Crater and flows south.

Frequent observations of the cone and channel are made throughout the day and night to track changes that could lead to signfiicant breakouts beyond the current flow field.

Lava has a brighter glow near the vent exit where it is more turbulent than in the downstream channel, which has portions of darker, cooled crust on its surface.

Lava within the Fissure 8 cone roils and churns where it eupts from the vent and flows rapidly down the well-established channel.

The lava channel from Fissure 8 jumped its banks near Kapoho Crater where the channel makes a 90 degree bend.

The flow within the channel was diverted around a constricted area and joined the channel again “downstream” to the south (left).

Near the coast, the northern margin of the flow field is still oozing pasty lava at several points in the area of Kapoho Agricultural and Beach Lots.
