Rockfalls trigger explosions in Kīlauea's summit lava lake
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).

lava lake level was 38 m (125 ft) below the rim
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 Halemaumau lava lake
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.

bursting bubble on the surface of a lava lake
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.

Hydrotherm program output example
Example Hydrotherm output. Hydrotherm is a three-dimensional simulation of multiphase groundwater flow and heat transport in the temperature range of 0 to 1200 degrees Celsius and the pressure range of 1 to 1000 MPa.

Did aerial bombing stop the 1935 Mauna Loa lava flow?
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.

What do we call new land at Kīlauea's ocean entries?
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.

Typical lava lake activity at Kīlauea's summit
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.

Moku‘āweoweo's North Pit, looking to the west-southwest
View of Moku‘āweoweo's North Pit, looking to the west-southwest. The summit of Mauna Loa is the peak visible in the background, slightly left of center. The two linear features in the foreground are ramparts from previous fissure eruptions.
