HAWAII VOLCANOES NATIONAL PARK, Hawaii – Hawaii’s Kilauea volcano has officially erupted for the 40th time since 2024, the U.S. Geological Survey (USGS) said.
Rivers of lava flowed down several vents of the Halemaʻumaʻu crater on Hawaii‘s Kilauea volcano overnight Monday.

According to the USGS, intermittent lava flows and dome fountaining have been ongoing since the weekend.
Dome fountains are smaller bubbles of lava that are typically precursors to much taller lava fountains, which are essentially jets of lava ejected hundreds of feet into the sky.

According to the USGS, Kīlauea has been erupting episodically since Dec. 23, 2024, with each episode lasting less than 12 hours and separated by pauses that can be longer than two weeks.
The 40th eruptive episode began shortly after volcanic activity started this weekend.

In an update, the USGS indicated that the prolonged precursor activity observed over the weekend paved the way for the 40th eruption.
These eruptions are occurring in a part of the Hawaii Volcanoes National Park on the Big Island that has been closed since late 2007.
However, volcanic gas, which is made up of water vapor, carbon dioxide and sulfur dioxide, can be released during eruptions and can be hazardous to areas immediately downwind of the eruption.
Kilauea’s last eruptive episode was on Dec. 24, 2025.
