Collapse of Kīlauea's caldera floor has exposed South Sulphur Bank, prominent in the mid-19th century but covered as lava flows filled the caldera. The flat top of the white deposit shows how high the caldera fill reached. As the caldera floor dropped in mid-June 2018, South Sulphur Bank was again exposed. The height of the bank, now more than 65 m (213 ft), increases about 2.5 m (9 ft) with each collapse event at Kīlauea's summit. On the caldera floor, white patches lie along spatter ramparts formed in 1971 and 1974.

In Kīlauea Volcano's lower East Rift Zone, the Unmanned Aircraft Systems (UAS) team frequently works into the overnight hours, flying aircraft (also referred to as drones) that hover over the lava channel to collect data used to calculate lava velocity. The team also looks for significant channel overflows. The bright white area is the moon obscured by clouds.

Fissure 8 on Kīlauea's lower East Rift Zone continues to erupt, feeding a channel that carries lava to the coast. This aerial image captured during HVO's early morning overflight, shows the erupting vent (center) and near-vent part of the channel.

The main ocean entry, as observed early this morning, was located a few hundred meters (yards) northeast of the southern flow margin, which remains about 500 m (0.3 mi) from the boat ramp at the Isaac Hale Park.
