Early morning view of the open lava channelbeginning about 5 km (3.1 miles) from Fissure 8.

Lava continues to erupt at a high rate from Fissure 8 and flow within the established channel to the ocean. No channel overflows were observed during this morning's overflight.

Halema'uma'u crater at 8:30 a.m., view is toward the south. Several benches are clearly visible within the crater.

USGS Hydrologic Technician Kammy Durham measuring discharge of Elk Creek near Rapid City, SD (streamgage 06407500), to capture peak flow after heavy rains during the week of June 18, 2018. The flow at this streamgage was 81 cubic feet per second on June 21, 2018.

USGS Hydrologic Technician Kammy Durham measuring discharge of Spring Creek near Keystone, SD (streamgage 06407500), to capture peak flow after heavy rains during the week of June 18, 2018. The flow at this streamgage was 69 cubic feet per second on June 21, 2018.

Early morning view of the ocean entry. The lava fountain from fissure 8 is visible behind the laze plume rising from the entry point. The open lava flowchannel is visible just beyond the solidified darker flows in the foreground.

Fissure 8 continues building a tephra cone and producing a robust channelized lava flow on Kīlauea Volcano's Lower East Rift Zone.

The USGS UAS (unoccupied aircraft system) team took this photograph of Halema‘uma‘u Crater from the Kīlauea Overlook on this morning. They are preparing for a flight to map further subsidence at the summit.

At a wide point in the channelized lava flow, a ropy crust has formed over the more fluid lava below.

On June 20, 2018, hydrologic technician Kammy Durham measured a discharge of 209 cubic feet per second on Whitewood Creek above Whitewood, SD (streamgage 06436180) after the watershed received about 2 inches of rain the previous evening. Streams in the Black Hills of western South Dakota can rise and fall quickly in response to rain.

Geologist makes early morning observations of the lava fountain and channelized flow at fissure 8 in Leilani Estates.

Fissure 8 lava fountains reached as high as about 50 m (164 ft) during the past day.

A temporary GPS station (with radio telemetry for continuous measurement) was installed this week on the Kīlauea caldera floor to track the ongoing subsidence of the summit area. The data will help to characterize the extent and rate of the subsidence.

View of the southern edge of the growing Halema‘uma‘u crater (middle right) during yesterday's helicopter-assisted work at Kīlauea's summit. The once-popular parking lot (closed since 2008) that provided access to Halema‘uma‘u is no longer—the parking lot fell into the crater this past week as more and more of the Kīlauea Crater floor slides into Halema‘uma‘u.

Lava from fissure 8 travels about 13 km (8 mi) to the ocean in an open channel. Lava remains incandescent (glowing orange) throughout its journey. The ocean entry is at upper right.

Small streams of lava enter the ocean across a broad area, shown by the multiple white steam and laze plumes. Lava has added about 380 acres of new land into the sea.
