On the morning of January 7, 2025, USGS Hawaiian Volcano Observatory staff made observations and measurements of the 2024-2025 Halema‘uma‘u vents, which ceased eruption in the evening on January 3, 2025. Both the North and South vents continue to emit volcanic gasses, contributing to vog that has been widespread across the Island of Hawai‘i since Saturday. The plume was being blown by Kona winds to the North and Northeast today. No jetting or other sounds were heard by field crews and no lava flows observed—the eruption remains paused. The South cone height was measured at 36 meters (118 feet), and the North cone was 23 meteres (75 feet) high. Subsidence of the lava surface near the vents after the eruption waned was on the order of about 5 meters (16 feet). USGS photo by K. Lynn.

Rockfalls continue from the steep caldera walls of Kaluapele, above the new cinder cone within Halemaʻumaʻu at the summit of Kīlauea. Large blocks roll down the flanks of the cone that formed between December 23, 2024, and January 3, 2025, leaving paths in the tephra cone material. USGS photo by M. Patrick.
