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.

New research from the University of St Andrews has precisely dated an eruption from Newberry Volcano and discovered that its ash spread more than 5,000 km across the globe, far further than previously thought for an eruption of its size.

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.

It's a truism among oceanographers that there is more accurate mapping of the surface of the moon and Mars than of the deep-ocean floor. That's especially true for the Bismarck Sea, a relatively deep body of water north of Papua New Guinea.

Tiny crystals suggest extinct volcanoes could still grow underground, a finding that could reshape how scientists assess eruption risk.
