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

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.

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

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

This thermal map shows the fissure system and lava flows as of 6 am on Thursday, June 21. The fountain at Fissure 8 remains active, with the lava flow entering the ocean at Kapoho. Very small, short flows have been active near the Fissure 6 and Fissure 16/18 area. The black and white area is the extent of the thermal map.

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.

HVO geologist measures 260 degrees C (500 degrees F) along ground cracks near fissure 10 in Leilani Estates. Geologists routinely make temperature measurements to track changes throughout the fissure complex in the lower East Rift Zone.

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

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.

Sluggish pāhoehoe briefly spills over a section the levee along the well-established lava channel. Such overflows generally travel short distances measured in meters (yards).

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.

Fissure 8 lava fountains obscured by a longer exposure photograph taken early morning on June 18. The incandescent spots along a horizontal line mark the edge of the lava channel. A tongue of incandescent lava leads down to the right - a small overflow from the channel margin.

This thermal map shows the fissure system and lava flows as of 6 am on Saturday, June 19. The fountain at Fissure 8 remains active, with the lava flow entering the ocean at Kapoho.The channel is very full and is overflowing to produce short pahoehoe lava flows that overtop the levees.

Fissure 8 vigor increased overnight June 18-19 with lava fountains reaching up to 60 m (200 ft). Spatter built up the cone to the east and into the channel. In this photograph, spatter lands on the east cone and flows downward.

The northern channel margin of the fissure 8 lava flow. Small hill in the distance is the site of our PGcam. Overflows from the channel can be seen producing shiny black to silver pahoehoe flows (incandescent red breakout visible in center of photo). These flows are building up the channel margins and making the levees more robust.
