Kīlauea Volcano — Remobilized Ash Plume
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.

Kīlauea Volcano —
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.

Subsidence of caldera floor impedes ability to transmit data

Fissure 8 tephra cone changes shape through time
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.

Kīlauea Volcano — Halema`uma`u Panoramic
This panorama of Kīlauea's summit caldera was made about 10 a.m. HST from the Keanakāko‘i overlook on the south side of the caldera. Halema‘uma‘u is visible steaming to the left, and the ongoing ground cracking is visible in the center of the image.

Kīlauea Volcano — Documenting Fissure 8 Activity
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).

Kīlauea summit subsides and produces frequent earthquakes
On June 23, 2018 at 4:32 p.m. HST after approximately 17 hours of elevated seismicity, a collapse explosion occurred at the summit if Kīlauea. The energy released by the event was equivalent to a magnitude 5.3 earthquake.

Kīlauea Volcano — Fissure 8 Fountain
At fissure 8, fountains provide a vigorous supply of lava that exits the cinder cone and drops over a spillway to enter a well-established lava channel that extends to the sea.

Kīlauea Volcano — Lava Flows from Fissure 8
View to the southwest, looking "up" the lava channel. Lava flows from Fissure 8 (not pictured) through the open channel about 13 km (8 mi) to the ocean. Lava remains incandescent (glowing orange) along the entire length of the channel with sections of cooled lava (black) on the surface.

Kīlauea Volcano — Ocean Entry
Lava is entering the sea on the southern side of the entry area primarily through the open channel, but also along a 1 km (0.6 mi) wide area. The entry areas are marked by billowing laze plumes.

Kīlauea Volcano — Roadway Crack Observations
USGS field crews track activity in and around Leilani Estates in Kīlauea Volcano's lower East Rift Zone. Observations are also collected on a daily basis from cracks in the area of Highway 130, shown here (no changes in temperature, crack width, or gas emissions have been noted recently).

Kīlauea Volcano — Small Halema`uma`u Eruption (June 24, 2018)

Kīlauea Volcano — Animated GIF of Crater Subsidence
This animated GIF shows a timelapse sequence consisting of one image per day between June 13 and 24. The photos were taken from the southern caldera rim, near Keanakāko‘i Crater, and look north towards HVO and Jaggar Museum.
