During an HVO eruption monitoring overflight on September 11, 2023, HVO geologist were able to land on the downdropped block within Kīlauea's summit caldera. They observed the line of erupting vents, several of which are visible in this video, as they searched for a safe location to collect a lava sample.

Another eruption at the summit of Kīlauea volcano began at 3:13 p.m. on September 10, 2023. This video, captured by the Hawaiian Volcano Observatory's B2cam on the east rim of Halemaʻumaʻu crater, shows the opening phase of the eruption. A lava fountain bursts from a degassing area in the eastern portion of Halemaʻumaʻu crater.

Geysers and hot springs are some of the most dynamic geologic features on the planet. They are always changing and sometimes that change happens in places where we can see and appreciate it. This has been the case on Geyser Hill, near Old Faithful, in Yellowstone National Park.

Could an external event trigger a Yellowstone eruption? No, says Yellowstone Volcano Observatory’s scientist-in-charge Mike Poland, that’s not how volcanoes work. Most of the pressure that drives a volcano toward eruption comes from within, from the exsolution of gases in the magmatic system.

Lava lake activity continues in Halema‘uma‘u crater, at the summit of Kīlauea, on January 20, 2023. This time-lapse sequence shows an hour and a half of activity in the eastern lake. Lava upwells at the fountain source and spreads out towards the lake margin, where it downwells. Overall, activity in the crater has been steady in recent days.

The eruption in Halema‘uma‘u crater, at the summit of Kīlauea, continues with steady lava lake activity. The largest lake is in the eastern portion of the crater, and is supplied by a single fountain. A smaller lake is also active in the western portion of the crater, along with two other much smaller lakes.
