Kilauea Message 2025-08-06 13:23:05 HST
Episode 30 lava fountains from the north vent ceased erupting at 12:55 PM HST today August 6. The south cone quit erupting about 5 minutes earlier. Summit tiltmeters recorded over 22 microradians of tilt loss, View All Messages.
Kilauea Message 2025-08-06 02:35:29 HST
The southernmost vent is a new fissure that opened up around 1:12 AM HST this morning. It was accompanied by a small cluster of earthquakes and some ground deformation. View All Messages.
Kilauea Message 2025-08-06 01:27:58 HST
More vigorous dome fountaining began at both vents at 1:20 AM HST. Fountains from the north vent rapidly grew and are now approximately 30-70 feet high (10-20 meters) and increasing. View All Messages.
Kilauea Message 2025-08-06 01:17:12 HST

Kilauea Message 2025-08-06 01:08:47 HST
Lava became visible with spattering in the north vent at 12:55 am HST and began vigorously overflowing at 12::56 am HST. This appears to be the start of precursory overflows of degassed lava preceding the onset of episode 30 fountaining. 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.
