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.

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.

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.

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.

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.

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.

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.

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.
