Kīlauea summit

Kīlauea Volcano’s summit, seen here from the northeast rim of the caldera, has remained quiet, with no collapse events since August 2. It remains too soon to tell if this diminished activity represents a temporary lull or the end of summit collapses. HVO continues to record detailed

View Into Fissure 8 Cinder Cone

The Unmanned Aircraft Systems (UAS) team assessed conditions at the fissure 8 cone and upper lava channel on August 17, 2018. At the time of the flight, the lava pond within the cone had crusted over with no observed incandescence. The reddish-brown rock inside the cone is the result of oxidation; the interaction of heated rock and gases causes black basaltic cinders to

3D Model of Fissure 8 Cone

This 3-dimensional computer model shows the structure of the fissure 8 cone on Kīlauea Volcano's lower East Rift Zone. The model was created from thermal images acquired during a helicopter overflight on August 15, 2018. The cone is currently about 30 m (100 ft) tall with a broad base. The bright white area within the cone is a small pond of lava, now largely crusted over

Pohoiki boat ramp and sand bar

Close view of the Pohoiki boat ramp during this morning's overflight. The southern-most flow margin has not advanced significantly toward the Pohoiki boat ramp, but black sand and larger fragments from the entry areas have washed ashore to create a sand bar and beach at this site. Geologists observed several small

Lava Entering Ocean Near Isaac Hale Beach Park

Lava continues to enter the ocean near the Isaac Hale Beach Park on Kīlauea Volcano's lower East Rift Zone. Although lava output from fissure 8 remains low, the ocean entry was still active during HVO's helicopter overflight on August 9, 2018. Numerous small streams of lava were oozing into the ocean near Ahalanui, creating weak plumes of laze. The southern flow margin

Overflight of Kīlauea Summit

Between mid-May and early August, 2018, the depth of Halema‘uma‘u more than tripled and its diameter more than doubled as magma from Kīlauea's shallow summit reservoir moved into the lower East Rift Zone. Evidence of subsidence is visible in this video, taken during an early morning helicopter overflight on August 6, 2018. Cracks and down-dropped blocks of the caldera

Lava Fountaining at Fissure 8

During this morning's overflight, HVO geologists observed low levels of lava fountaining within the fissure 8 spatter cone and crusted lava in the spillway and channel downstream. The significance of this change is not yet clear. Eruptions can wax and wane or pause for days to weeks before returning to high levels of lava discharge. New outbreaks in the area of the active

New outcrops make good geology

This aerial view of the western part of Kīlauea Volcano's caldera was taken on August 6, 2018. The down-dropped block is faulted about 120 m (400 feet) below the caldera floor. Many 19th-century lava flows are exposed in the fault scarps. Halema‘uma‘u (not visible) is to the left of this photo.

Hot, molten lava flows slowly into the ocean, and the temperature difference between lava and water is creating steam.

Since May 3, 2018, Kīlauea Volcano's lower East Rift Zone eruption has destroyed more than 700 structures, covered more than 32 sq km (12.4 sq mi) of land with black lava, and added about 700 acres of new land to the island. Yet, remarkably, injuries had been few.

For many Hawaii residents, interactions with Kīlauea Volcano's eruptions is through vog—a hazy mixture of sulfur dioxide gas and sulfate particles. However, sulfur on Kīlauea is not limited to vog components.
