Kīlauea has busy week; new episode begins

Kīlauea: a youngster among world's active volcanoes

This video shows a rockfall and subsequent explosion that occurred at 7:03 a.m. HST today within the "Overlook crater" at the summit of Kīlauea. This collapse was followed by a smaller rockfall at 7:07 a.m. (not shown in video).

On January 8, 2018, Kīlauea Volcano's summit lava lake level was 38 m (125 ft) below the rim of "Overlook crater," the small crater that formed above the active vent in Halema‘uma‘u.

Kīlauea Volcano's Kamokuna lava delta on October 6, 2017. Multiple streams of lava entering the ocean on both sides of the delta created small plumes of laze (lava haze). The visible part of the delta, which is deceptively stable, was built by many small lava flows accumulating on an unstable foundation of unconsolidated volcanic rock fragments. USGS photo by L.

Kīlauea Volcano's summit lava lake activity over the past few days has been typical, with intermittent sites of spattering and migration of the crust from north to south (top to bottom of image). This view of the lava lake was captured on the evening of Saturday, November 18.

The lava lake within Halema‘uma‘u, a crater at the summit of Kīlauea, was about 30 m (98 ft) below the vent rim on the day of this photo (January 7, 2016).

This view of Halema‘uma‘u as it appeared in the 1917 relief model by George Carroll Curtis shows fine details around the crater, including the first road for automobiles, which ended near the crater rim. The light-colored circular feature around Halema‘uma‘u is a nearly continuous escarpment along which subsidence occurred. Photo by Burr A. Church.

The 1917 Curtis relief model of Kīlauea Volcano's summit shows many well-known geologic features, including the summit caldera (large depression), Halema‘uma‘u (crater within the caldera), Kīlauea Iki (crater at far right), and elaborate drainage patterns (foreground). Photo by Burr A. Church.

Spattering is common in Kīlauea Volcano's summit lava lake, and consists of many large bursting gas bubbles. The fluid nature of the lake can be seen when lava hits the wall and flows downward like syrup. The thin, flexible nature of the crust is also shown here, as the bursting gas bubbles rip and fold the thin skin on the lake.

This perched lava channel, which was as much as 150 feet (45 meters) above the ground, carried lava downslope from the Pu‘u ‘Ō‘ō Fissure D vent during episode 58 of Kīlauea Volcano's ongoing East Rift Zone eruption. The channel was the main path for lava between July and November 2007. Episode 58 continued until early March 2011.

A beautiful sunset over Mauna Loa (in distance at left) provided a backdrop to the lava lake within Halema‘uma‘u. HVO and Jaggar Museum are on the horizon near the center of the panorama.

Kīlauea Volcano's Kamokuna ocean entry photographed on May 23, 2017 (left) and July 13, 2017 (right) show how lava flowing from the tube has both widened and thickened the delta. Near the sea cliff, the delta appears to have doubled in thickness over the past seven weeks, creating a distinctly sloped surface from the base of the cliff to the sea.

This video clip shows Kīlauea Volcano's Kamokuna ocean entry, with the steam plume rising from the front of the lava delta. Recent flows have covered the surface of the delta with fresh lava.

On the evening of June 30, 2008, littoral explosions at Kīlauea Volcano's Waikupanaha ocean entry created a fireworks-like display as incandescent fragments of lava flew through the air. When molten lava entered the sea, the water flashed to steam, triggering explosions that hurled spatter and other lava fragments up to heights of 50 m (164 ft).
