Kīlauea: a youngster among world's active volcanoes

Lava consolidates but flow remains steady

Red circles represent all seismicity and blue circles represent earthquakes as part of earthquake swarms. The size of the circles is scaled to the magnitude of the earthquake. The 630,000 year old Yellowstone caldera is shown as a bold black line within Yellowstone National Park. Mapped faults are shown as light gray lines.

"Dimples" in the Pele's hair that has accumulated on the rim of Halema‘uma‘u are evidence of ballistic impacts during today's rockfall-triggered explosion in Kīlauea Volcano's summit lava lake. Spatter (fragments of molten lava) blasted from the lava lake landed all around HVO's thermal camera (HTcam) that monitors lake activity.

Spatter up to about 30 cm (11.8 in) in size was hurled onto the rim of Halema‘uma‘u during today's explosive events. Some fragments were thrown or blown farther downwind, reaching as far as the closed section of Crater Rim Drive in Hawai‘i Volcanoes National Park.

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).

The Dec. 4, 2017 Thomas fire, Southern California's largest wildfire on record, burned more than 280,000 acres across Ventura and Santa Barbara counties for nearly a month.

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.
