Kilauea Message 2025-11-22 20:15:15 HST
There have been 24 south vent overflows since 9 a.m. HST this morning. The last one went from 18:50 to 20:03 and had sustained dome fountains approximately 30 feet (10 meters) high. Most of the rest of the overflows were short-lived. View All Messages.
Kilauea Message 2025-11-21 18:07:13 HST
Intermittent overflows have been alternating between the north and south vents in irregular cycles all afternoon and evening. Magma remains high in the conduit and episode 37 fountains are forecast for Nov 21-25 with Nov 22-24 most likely. View All Messages.
Kilauea Message 2025-11-21 11:01:31 HST
Both the south and north vents overflowed at the same time from 10:27 to 10:36 am HST. A second overflow from the north vent took place from 10:42 to 10:54 am HST. Multiple precursory overflows are expected prior to episode 37 fountains. View All Messages.
Kilauea Message 2025-11-21 09:50:07 HST
The south vent overflowed from 9:27-9:39 am HST indicating magma is high in the vent. The degassed flow was short and sluggish. Precursory overflows preceded the last several fountaining episodes and more are expected prior to episode 37. View All Messages.
Kilauea Message 2025-11-20 22:55:22 HST
Resend for X. Short bursts, under 1 minute, of spattering from the north vent occurred at 9:20 pm and 9:28 pm HST tonight. More vigorous bursts occurred from 9:46 to 9:52 pm HST. V1 camera was rebooted to remove lag and V3 was zoomed in. 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.
