Lava Update | July 16, 2018

Kilauea’s eruptive activity persists on its lower east rift zone, as fissure 8 continues to discharge an extraordinary volume of lava, estimated to be in the neighborhood of 100 cubic meters of lava per second. Although we’ve observed fluctuations in levels within the channelized flow, there has not been a noticeable decline in output from the vent. That being said, although levels appear to be “normal”, one of the channels in the braided section has been drained of lava, more than likely a result of a blockage. Downstream, the channelized ‘a‘a flow continues to push material onto the coastal plain, but the ocean entries seem to be a little subdued as compared to a couple days ago. Could the lava be accumulating beneath the ‘a‘a field’s surface? Only time will tell. And for the moment, southward expansion toward Pohoiki has stalled. See the latest photos below.

The discharge channel from fissure 8 rages with swift flowing lava, feeding into the perched channel within the Leilani Estates subdivision.
Southward expansion of the flow field at Ahalanui has stalled for the moment, but the concentrated entry point remains active, generating a robust plume of laze.
A section of the braided channels has been drained of molten material, but the remaining river continues to feed the ‘a‘a flow on the coastal plain and the ocean entry.

Fissure 8 continues to effuse lava at a rapid rate, feeding the 8 mile long channelized flow to the sea.

The ocean entry at Ahalanui continues to pour into the sea, generating a robust plume, but its southward expansion seems to have stalled for the moment, and remains approximately a 1/2 mile from Pohoiki.
The ocean entry at Kapoho remains active with multiple fingers of lava entering the sea.
The tiny island that formed off of the Kapoho coast has transitioned into a peninsula, and continues to bleed a small amount of lava.

  1. Incredible. The big view shots are very useful to see as much of the eight mile flow as possible. It’s incredible that it stays molten for the entire journey to the sea. How long do you think it takes a given piece of lava to go from the crater to the sea? How fast is it moving? Thanks.
