December 2, 2025—Solidified lava channel from the north vent in Halemaʻumaʻu, Kīlauea summitThis black solidified lava channel is a stark contrast to the weathered brown walls of Halemaʻumaʻu crater nearby. The lava channel transported lava from the north vent, along the north rim of the crater, allowing lava flows to reach the farthest regions of the crater to the east during the 9 hours of lava fountaining of episode 37 on November 25, 2025.

November 25, 2025—Video of Kīlauea summit eruption episode 37Episode 37 of the Kīlauea summit eruption in Halemaʻumaʻu began November 25 at 2:30 p.m. with lava fountaining from the north vent. A wide fountain developed, eventually reaching heights of 500-600 ft (150-180 meters), sending flows across a broad portion of the crater floor.

Lava overflow activity prior to episode 37
USGS Hawaiian Volcano Observatory geologists observed lava roiling in the north and south vents at the summit of Kīlauea on Friday, November 21. Shortly after, lava flowed onto Halemaʻumaʻu crater floor for the first time since episode 36 (November 9). That activity continued through the weekend, with 73 overflows total.

The closer camera sustained heat damage during the intense episode 35 fountaining, making the image slightly blurry.

Lava lake activity from inside Halema`uma`u Crater
Lava lake activity from inside Halema`uma`u CraterSounds of lava lake activity within Kilauea Volcano's summit vent inside Halema`uma`u Crater on the afternoon of February 14, 2011. The continuous "crashing wave" noise is the sound of churning lava as gases are released from the lake surface, which is in nearly constant motion.

Dramatic Developments at Kilauea Volcano
Kilauea Volcano in Hawaii has experienced its first explosive eruption in more than 80 years and is now spewing noxious gas at 10 times the normal rate. John Eichelberger, head of the USGS Volcano Hazards Program, fills us in on the situation.
