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.

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).

"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.

Spectacular aerial view of Kīlauea Volcano's East Rift Zone lava flows advancing over Pūlama pali in December 2017. As surface lava flows moved through the center kipuka (forested area) on the pali, smoke rose from the burning vegetation.
