Cone building and lava flow generation at fissure 8 continues
The Fissure 8 viewed from the north at 7:50 AM. The cone is roughly 50 m (165 ft) high at is peak, and a plume of sulfur dioxide and other volcanic gases rises as an orange tinge from the erupting lava fountains (hidden within the cone). Lava is still flowing out of the vent unabated as a full channel. To the left of the cone, a standing wave of lava can be seen in the channel.
Ocean entry is active along the length of the flow front
Several laze plumes rise along the ocean entry margin as break outs feed many small and large flows. The largest pāhoehoe breakout area is on the northern margin of the flow (furthest plume in this image).

A helicopter overflight video of the lower East Rift Zone on June 14, 2018, around 6:00 AM, shows lava fountaining at fissure 8 feeding channelized lava flows that flow into the ocean. Lava is still flowing out of fissure 8 unabated and the channel is full. At the start of the video, standing waves in the lava channel can be seen near the vent exit. The channel appears crust-free from vent to the bend around Kapoho Crater. A surface crust forms over the channel as it spreads out during its approach to the ocean. The overflight along the ocean entry is from north to south along the coastline. The ocean entry is active along the whole length - approximately 1 mile. Small litoral explosions are occurring and there are several plumes of laze.
Changes at Halema'uma'u over time
This is a comparison of photos taken from the same location in the Volcano House on May 19 and June 13, 2018. The focal length of the lens for each photo is almost the same. The photos show the enlargement of Halema‘uma‘u laterally and vertically. Note how much lower the rim is relative to the tree in the lower photo.
