Kilauea, located on Hawaii's Big Island, is showing signs of imminent activity, according to the Hawaiian Volcano Observatory. Summit inflation -- or the physical swelling or uplifting of the ground surface of the volcano's peak -- is underway, it said.

Scientists say a massive 2022 volcano eruption may have helped break down methane, offering new clues in the fight against climate change.

Episode 47 of the ongoing eruption at Kīlauea summit began Thursday afternoon with lava fountaining from the north vent in Halema’uma’u crater, according to the Hawaiian Volcano Observatory. The eruption began at approximately 3:33 p.

A magnitude 6.0 earthquake struck Hawaii's Big Island, causing widespread shaking but no eruption or tsunami. Authorities confirmed the quake was due to tectonic activity, not volcanic processes.

An underwater volcano in the Pacific, Axial Seamount, reveals a process that could challenge current theories about the Earth's crust.

Kīlauea has erupted episodically since Dec. 23, 2024, within the summit caldera. Episode 47 of lava fountaining happened for 9 hours May 14-15. No unusual activity is noted along Kīlauea’s East Rift Zone or Southwest Rift Zone.
