The lava lake at Kīlauea's summit remains high, probably 45-50 m (150-165 ft) below the floor of Halema‘uma‘u crater. This view, looking toward the southwest, shows the lava ledge on the rarely seen southern side of the pit. The spattering is at the point where the circulating lava lake sinks back down.

A closer view of the spattering at the point of downwelling. From the position of the Halema‘uma‘u webcam at the visitor overlook, the spattering looks like it might be at the base of the crater wall. This photo shows that the spattering is actually 60-70 m (200-230 ft) out from the wall, toward the center of the pit.

The small lava lake in the pit on the northeastern side of the Pu‘u ‘Ō‘ō crater floor remains active as well. Lava rises at the right side of the lake (west) and sinks where the heavy fume is rising at the left side (east).

The lava lake at Kīlauea's summit was about 46 m (150 ft) below the floor of Halema‘uma‘u crater today—the highest it has reached.

Advancing surface flows reached the base of the Pūlama pali over the past few days, burning through one of the few remaining forested kipuka in the abandoned Royal Gardens subdivision. The white line marks the outline of the active flows.

Shaded relief is taken from airborne LiDAR data. Snowfields are not labeled except for Palmer, which is a recognized feature. It is not a glacier although it is labeled such on some maps.

The breakout from the upper flow field that began earlier this month is still active, with flows currently moving through the upper portion of the mostly-buried Royal Gardens subdivision. On the left is a conventional photograph, and on the right is a view with a thermal camera covering a similar area.

The lava pond in the northeast portion of Pu‘u ‘Ō‘ō crater remains active, with persistent spattering at the pond margins and a slowly migrating lava surface. A time-lapse camera mounted on a tripod on the rim (left edge of photo) provides a sense of scale.

A small skylight has been open for several weeks on the upper tube system, just southeast of Pu‘u ‘Ō‘ō, providing a view of the lava stream within the lava tube. The lava rushing through the tube here is supplying the active surface flows shown in the image above this one.

Flows remain active above the pali, near the top of the mostly-buried Royal Gardens subdivision. The slowly advancing pāhoehoe toes had a silver appearance in the bright sun today.

A lava pond, about 30 m (100 ft) wide, has been active for several months within a collapse pit in the northeast portion of the floor of Pu‘u ‘Ō‘ō crater. This thermal camera image shows the lava pond within the pit, as viewed from the east rim of Pu‘u ‘Ō‘ō.
