Kilauea Message 2025-12-05 20:50:57 HST
The north vent is a boiling cauldron of lava tonight and the south vent is spattering too. There have been 4 precursory overflows since just before 1 pm HST this afternoon and more overflows are expected before the fountain finale begins. View All Messages.
Kilauea Message 2025-12-05 12:56:52 HST
The first precursory overflow of lava from the north vent began at 12:52 pm HST and ended less than 2 minutes later. Inflation models indicate that the onset of episode 38 fountaining is likely to be December 6 or 7 with Dec 8 less likely. View All Messages.
Hawaiian Volcano Observatory Message 2025-11-26 00:48:22 HST
Episode 37 lava fountains from north vent reached heights of 500-600 ft (150-180 m). No flows or fountains erupted from south vent. Eruptive plume reached heights over 14,000 ft (4,200 m) above sea level. View All Messages.

HVO monitors earthquakes and the active volcanoes in Hawaii, assesses their hazards, issues warnings, and advances scientific understanding to reduce the impacts of volcanic eruptions. Communicating the results of our work to the public, emergency managers, and the scientific community is an important aspect of the HVO mission.
