KILAUEA (VNUM #332010)
19°25’16” N 155°17’13” W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: 

Episode 7 of the ongoing Halemaʻumaʻu eruption began at 6:41 pm HST on January 27 and is currently feeding a small flow onto the crater floor.

Episode 7 was preceded by small, sporadic spatter fountains that began at approximately 1:30 p.m. and continued to increase in intensity until 6:41 p.m., when sustained fountaining began. Fountains from the north vent are 100-120 feet (30-40 meters) high and feeding multiple lava streams at 7:40 pm HST. The flow had covered 15-20% of the crater floor this time. A small fountain can be seen in the south vent and there is a small lava flow emerging from the south side of its cone at 7:35 p.m. HST on webcams.

Inflationary tilt at the summit recovered the 2.5 microradian tilt loss during episode 6 by 3:00 p.m. on January 27 and had increased another 0.5 microradians just before episode 7 started. Seismic tremor began increasing and tilt at UWD switched from inflation to deflation at about 6:40 p.m. about the same time lava flows began erupting onto the crater floor.

No changes have been detected in the East Rift Zone or Southwest Rift Zone.

Each episode of lava fountaining since December 23, 2024, has continued for 13 hours to 8 days and episodes have been separated by pauses in eruptive activity lasting a less than 24 hours to 12 days. Based on the durations of episodes 5 and 6 and the short pauses that separated them, episode 7 will probably last 10-20 hours.

HVO continues to closely monitor Kīlauea and will issue an eruption update tomorrow morning unless there are significant changes before then.

HVO remains in close contact with Hawai‘i Volcanoes National Park and the Hawai‘i County Civil Defense Agency. Please see the Hawaiʻi Volcanoes National Park website for visitor information: https://www.nps.gov/havo/index.htm

Hazards: 

The eruption is occurring within a closed area of Hawai’i Volcanoes National Park. High levels of volcanic gas—primarily water vapor (H₂O), carbon dioxide (CO₂), and sulfur dioxide (SO₂)—are the primary hazard of concern, as this hazard can have far-reaching effects downwind. As SO₂ is continuously released from the summit during an eruption, it will react in the atmosphere to create the visible haze known as vog (volcanic smog) downwind of Kīlauea. Vog information can be found at https://vog.ivhhn.org/.
