View of the ocean entry (lower left) from this morning's overflight. Lava was entering the ocean across a broad area primarily on the north part of the lava delta.

Near the coast, the northern margin of the lava flow field is still oozing fresh lava at several points in the area of Kapoho Beach Lots. Smoke marks locations where lava is burning vegetation.

Night view of the lava channel toward fissure 8 under a nearly full moon. This image was taken from an observation point near the right-hand bend in the channel where it turns southward around Kapoho Crater.

Continued eruption at Fissure 8 feeds the voluminous lava channel to the ocean as seen during this morning's overflight of the lava-flow field.

Overflows from the perched lava channel are seen as incandescent (glowing) fingers moving down the sides of the channel (left side of photo). Fissure 8 lava fountain in photo center.

A small overflow from the lava channel (left side of image) captured by an Unmanned Aircraft System (UAS). Small overflows on both sides of the channel occurred shortly after midnight in the uppermost part of channel. None of these overflows extended past the existing flow field.

Lava continues to enter the sea along the southern Kapoho coastline. Lava enters the ocean primarily through an open channel, but also along a 1-km (0.6 mi) wide area. Also visible in the image (center right) is an area at the northern margin of the flow field that is oozing fresh lava at several points in the area of Kapoho Beach Lots.

Lava from fissure 8 is entering the sea this morning on the southern portion of the flow front primarily through the open channel, but also along this 1 km (0.6 mi) wide area with multiple laze plumes from smaller oozing lobes.

A UAS mission on June 24, 2018, filmed details of the dramatic changes occurring within Halema‘uma‘u crater at Kīlauea's summit since explosive eruptions of ash and gas and ongoing wall collapse began in mid-May. Clearly visible are the steep crater walls that continue to slump inward and downward with ongoing subsidence at Kīlauea's summit.

Southward facing view of the point at which the fissure 8 lava channel bifurcates.

North facing view of the 1 km (0.6 mi) long ocean entry with multiple lobes of lava flowing into the sea.

Lava within the braided portion of the fissure 8 channel is flowing within its banks. View looking downstream toward the sunrise over the ocean entry.

After 100 years of restricted tidal activity to support agricultural use and salt harvesting, the tidal marshes around San Francisco Bay, like this one at Bair Island, are steadily rebuilding, returning to a stunning mosaic of marsh, mudflat, and channels.

Recent explosive events haven't produced significant ash plumes from the summit, but downwind communities may still experience ashfall when previously erupted ash is remobilized. On authorized permission from Hawai‘i Volcanoes National Park, our Unmanned Aircraft Systems crew is conducting gas measurements at Pu‘u ‘Ō‘ō.

Comparison of photographs taken on June 13 and 26 from near Keanakāko'i Crater overlook in Hawai'i Volcanoes National Park shows a subsidence scarp that formed as the Kīlauea Crater floor subsided. Scientists estimate the dramatic dropping of the crater floor in this area occurred sometime between June 23 and 26. The view is to the west.

USGS Hawaiian Volcano Observatory geology field crews maintain watch over the eruptive activity in the lower East Rift Zone and at Kīlauea's summit. Here, a geologist documents the behavior of lava as it exits the Fissure 8 cone. Lava enters the upper channel traveling as fast as 30 km/hour (18 mi/hour).

This animated gif shows the fissure 8 tephra (cinder and spatter) cone morphology changes between June 15 and 24, 2018. During this time a shoulder grew on the channel side of the cone as the vent shifted from being two distinct fountains to three, then to a single source of voluminous roiling.
