Episode 41 started at 11:10 a.m. As of 11:50 a.m., both north and south vents are over 250 m (820 feet) high, and the summit tilt on UWD has already recorded 3.5 microradians of deflation.
Kilauea Message 2026-01-24 11:12:02 HST
Precusory overflows continue from both vents with increasing fountains. Summit tilt on UWD began slow deflation at 10:15 that is continuing and tremor is increasing rapidly. Episode 41 fountaining has started.

The south vent has been overflowing continuously since 10:07 am HST. Sustained dome fountains 10-20 feet (3-6 meters) high at both vents are feeding precursory lava flows out into the middle of Halemaʻumaʻu crater.

The north vent has been overflowing continuously since 3:52 am HST while the south vent continues to have intermittent overflows related to gas pistoning in the vent. Episode 41 fountaining is likely to begin today. See Update for more.

A large overflow from the south vent began at 6:40 a.m. HST and is continuing at this time. The north vent continues to overflow as well.

Small fountains became visible in the south vent became visible just before 6 am HST and another short overflow occurred from 6:13-6:16 am. Overflows continue from the north vent.

The north vent has been overflowing continuously since 3:52 am HST. Spatter fountains grew to 10-15 feet high with an increase in effusion rate at about 4:47 am. Lava overflowed the south vent twice for a few minutes at 3:11 and 5:18 am.
Kilauea Message 2026-01-22 23:22:08 HST
A second small overflow from the north vent began at 11:13 pm HST and died within 2-3 minutes. Additional precursory overflows are expected prior to the start of episode 41 fountaining forecast for January 23-25.
Kilauea Message 2026-01-22 22:59:38 HST
Spattering at the north vent became more vigorous at about 10:40 pm HST and fed a small overflow. The overflow lasted for about 5 minutes before spattering died back.

Two seismic swarms beneath Halemaʻumaʻu and south caldera January 19 at 1:37 pm and 9:25 pm HST. The latter lasted 20-30 minutes and triggered a 1.5 microradian drop in UWD tilt. Strong glow from vents was not affected by this event.
Kilauea Message 2026-01-19 04:21:54 HST
Seismic swarm with about 20 small earthquakes began at 2:58 AM HST and lasted for about 30-40 minutes. A smaller swarm occurred just prior to 4 PM HST yesterday. Both swarms caused minor tilt drops, but no impact to eruption or rift zones.
Kilauea Message 2026-01-15 19:15:49 HST
There was a fourth seismic swarm that began beneath the southeast side of Halemaʻumaʻu at about 4 p.m. HST and continued for about 20 minutes. The summit tiltmeters were not effected and all activity remains within the summit region.
