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.

First high-definition thermal image of the Halema‘uma‘u lava lake in the New Year, taken shortly after midnight on January 1, 2018. This camera was deployed to track the dynamic surface activity of the lava lake at the summit of Kīlauea.

Boxes of historical seismograms (thousands of them!) in the basement of the USGS Hawaiian Volcano Observatory in the summer of 2017. These records span over a century of earthquake monitoring in Hawaii. Dr. Thomas Jaggar installed the first seismometer in 1912, and paper records were used for recording into the 1990s.

A bursting bubble on the surface of a lava lake produces an impulsive signal on an infrasound recording. This photo shows a group of bubbles about 5 m (16 ft) across bursting on the Halema‘uma‘u lava lake at the summit of Kīlauea Volcano. The blue line is an infrasound recording of 50 seconds of similar activity.

Aerial view of a bomb detonating on Mauna Loa near the 8500-foot elevation source of the 1935 lava flow on the morning of December 27, 1935. This was one of twenty 600-pound bombs dropped on the lava flow that morning by the Army Bombing Squadron from Luke Field, O‘ahu. Photo by Army Air Corps, 11th Photo Section.

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.
