Hawaii, United States – A timelapse video of lava fountaining at the summit of Kīlauea shows molten lava spreading across Halemaʻumaʻu crater during May 14–15, 2026.

The footage was recorded by the B1cam, positioned on the south rim of Halemaʻumaʻu crater, capturing eruptive activity from the north vent and its movement across the crater floor.

The activity began at 3:27 p.m., when lava fountains fed flows that spread across the surface of the crater and slowly traversed its floor.

At 12:27 a.m. on May 15, lava stopped erupting from the north vent. However, lava flows continued their gradual movement across the crater floor through the night.

The flows remained present until sunrise on May 15, even after active fountaining had ended.
