Photo and Video Chronology — December 25, 2024 — Kīlauea summit eruption pauses
Lava began draining back into the vent at 11:00 a.m. on December 25, at nearly the same time that summit tiltmeters began recording a change from deflation to inflation. Seismic tremor also decreased markedly at the same time. The pattern was similar but more abrupt than the onset of the pause on Monday, December 23, that occurred between 3 and 4 p.m. Episode 2 lasted a little over 24 hours, which is about twice the duration of the first eruptive episode. Prior summit eruptions have lasted days to weeks and there is a high probability that this eruption will resume

Photo and Video Chronology — November 25, 2024 — Visiting the September 2024 Kīlauea eruption site
With permission from Hawai‘i Volcanoes National Park, team of USGS Hawaiian Volcano Observatory geologists visited the site of the September 2024 Kīlauea middle East Rift Zone eruption. They surveyed, sampled, and documented the new volcanic fissures and features, which formed west of and in Nāpau crater from September 15–20, 2024. This view, taken on Monday, November 25, 2024, around 8 a.m., looks to the east from the west rim of Nāpau Crater. The September 2024 lava flows on the floor of Nāpau Crater are visible in the foreground while Pu‘u‘ō‘ō, active from 1983–2018, is visible in the background. USGS photo
