FWIW: official USGS volcano information will always come from accounts that have the handles @USGSVolcanoes, @alaska_avo, & @USGS and are linked from our web pages.
Visit usgs.gov/programs/VHP/connec… for info.
Kilauea Message 2025-11-04 04:38:34 HST. Lava overflowed the south vent 4 times this morning starting at around 1:40 am HST and continuing to now. Flows are 100-200 feet long. The north vent continued to fill and drain periodically and had 2 small overflows this morning.
Kilauea Message 2025-11-03 01:58:48 HST. There have been 2 more events where small lava flows barely cleared the lip of the vent prior to drainback. The past 2 episodes have been preceded by 1-2 days of small overflows as degassed magma was pushed from the vent. More are...
Kilauea Message 2025-11-03 01:04:38 HST. The north vent overflowed from 12:46 to 12:53 am HST this morning. Both vents had been glowing strongly all night and magma could be seen slowly rising in the north vent all night. More overflows may occur prior to the start of...
Kilauea Message 2025-10-31 23:05:49 HST. Boo! Moderate tremor spikes and glow with hydrogen flames (after dark) from the north vent began at 5:30 pm HST. This sequence ended with a small overflow and vigorous drainback 9:25 to 9:28 pm. Tremor and glow became constant since then.
Kilauea Message 2025-10-18 04:07:16 HST. Episode 35 ended at 3:32 am HST when the north vent died, the south vent stopped erupting 3 minutes earlier. The episode 35 fountains lasted for 7.5 hours and produced about 13 million cubic yards (10 million cubic meters) of lava.
Kilauea Message 2025-10-17 22:11:14 HST. Record high fountains for this eruption, nearly 1500 feet high.

Kilauea Message 2025-10-17 21:31:41 HST. South vent has topped 1300 feet (400 meters) and north vent is about 1100 feet (330 meters), a record for two fountains during this eruption!
Kilauea Message 2025-10-17 21:19:36 HST. Both the north and the south vent are over 1000 feet (300 meters) with the south fountain about 1150 feet (350 meters) high.
Kilauea Message 2025-10-17 21:10:21 HST. Both the north and south vent fountains are now 600-700 feet (200-230 meters) high.
Kilauea Message 2025-10-17 21:04:48 HST. Fountains from the south vent began at about 8:50 pm HST and have grown rapidly to over 150 feet (50 meters) in the last 15 minutes. Both the north and south vents are feeding large flows on the the floor of Halemaʻumaʻu crater.
Kilauea Message 2025-10-17 21:01:23 HST. Episode 35 continues from the north vent with fountains about 500 feet (150 meters) high. The north vent fountain is currently angled at about 60 degrees to the north east, similar to episode 34. Minor fountaining from the south vent.
Kilauea Message 2025-10-17 20:25:30 HST. Episode 35 fountains began from the north vent at about 8:05 pm HST and fountains current are over 300 feet (100 meters) high. Fountains are expected to continue to grow and probably begin from the south vent as well.
Kilauea Message 2025-10-17 20:06:57 HST. Continuous precursory overflows began from the north vent at 7:28 p.m. HST October 17. Fountains are 30-50 feet (10-15 meters) high. Tremor is increasing and tilt is dropping, episode 35 fountains should start soon.
Kilauea Message 2025-10-17 17:50:26 HST. Precursory overflows (31 total) of degassed lava continue from the south vent along with spattering in the north vent. The onset of episode 35 fountaining could happen anytime between now and Tuesday with Saturday or Sunday most likely.
Hawaiian Volcano Observatory Message 2025-10-16 21:10:22 HST. 15 lava overflow-drainback events occurred at south vent between 7:35 AM and 9:00 PM, Oct 16. More are expected as we approach episode 35 fountaining. Vigrous intermittent spatter continues at north vent.
Hawaiian Volcano Observatory Message 2025-10-16 10:22:12 HST. Small lava overflows from the south vent occurred this morning at 7:35 AM, 8:50 AM, 9:29 AM. Each lasted ~12 minutes and ended with spattering and drainback. These will likely become more frequent as we approach...
Kilauea Message 2025-10-15 21:20:58 HST. Nearly continuous strong glow is coming from both the north and south vents. Intermittent spattering in the north vent began just after dark. Seismic tremor indicates sustained tremor changed to irregular gas...
Kilauea Message 2025-10-12 21:47:52 HST. Short spatter bursts were observed from the south vent at 9:09 and 9:32 pm HST and at 9:29 pm HST from the north vent. These indicate that magma is high in both vents and spattering events should increase in frequency over the coming...
