Photo and Video Chronology — December 23, 2024 — New Kīlauea summit eruption
This video, taken from the west rim of Kaluapele (Kīlauea caldera), in the closed area of Hawaiʻi Volcanoes National Park, shows the new eruption that started this morning at 2:20 a.m. HST. At approximately 4:30 a.m. HST, the lava fountains were reaching up to 80 meters (260 feet) and by 5:30 a.m., lava covered an area of approximately 400 acres on the caldera floor. Increased volcanic gas emissions downwind, within the closed area, require USGS field staff to use gas masks. USGS video by D. Downs.

At least a low-end multi-day regional severe risk is expected across south-central and east/southeast Texas towards parts of the ArkLaTex, and possibly the Lower Mississippi Valley.
