Amber lava exploded over 200 meters into the air as Kilauea, one of the world's most active volcanoes, erupted on Thursday. Lava fountains began to erupt from the volcano after 11 am local time.

'Due to its extent and location it is clear that this is in fact the same magma reservoir as in the previous eruption,' geophysicist Professor Seama Nobukazu said.

Few transformations in the history of life have been as extreme as the embrace of the ocean by seagrass. Like whales and dolphins, modern seagrasses descend from land-dwelling ancestors.

The eruption generated significant heat and ash, USGS said, with some six inches of tephrabits of volcanic material, ranging from glasslike particles to rocks and ashaccumulating on a nearby golf course. Some glassy material, called Pele's hair for its strandlike structure, traveled as far as the city of Hilosome 30 miles away by car, USGS said.

The 1993 erotic thriller Sliver should have ended differently: Zeke, played by William Baldwin, was scripted to fly a helicopter towards an active volcano, after Sharon Stone's character, Carly, reveals she's the killer. The pilot, Craig Hosking, had been tasked with flying low over Hawaii's Kilauea volcano, accompanied by the director of photography, Mike Benson, and his assistant Christopher Duddy, to film the bubbling lava and white plumes of smoke escaping from the Puu Oo vent.

Remembering the life and work of the geologist George Poulett Scrope, and salmon stories in this week's pick from the Nature archive.

Land is one of those things that can disappear even as you see it. It falls away beneath you, becoming merely the ground under your feet, because you're thinking about where you're going, or a place slowly blurring out of focus from the airplane window. Land is a primal word, primordial even, like lava. And it is a loaded word if, say, you're Indigenous or descend from a people whose land was taken from them.

The lava heron also has a much thicker bill than other closely related herons - an adaptation linked to feeding among sharp volcanic rocks and hard-shelled prey. "What we learned was something that hadn't been reported before," Mendales said. The discovery underscores how much remains unknown, even in iconic places like the Galápagos, said John Dumbacher, the Academy's curator of birds and mammals and Mendales' thesis adviser.

A team of geologists has found for the first time evidence that two ancient, continent-sized, ultrahot structures hidden beneath the Earth have shaped the planet's magnetic field for the past 265 million years. These two masses, known as large low-shear-velocity provinces (LLSVPs), are part of the catalog of the planet's most enormous and enigmatic objects. Current estimates calculate that each one is comparable in size to the African continent, although they remain buried at a depth of 2,900 kilometers.

It looked like the silvery blade of a knife. Peering through his goggles, diver Ted Judah had laid eyes on a deep-sea creature rarely encountered by humans. He and wife Linda were diving off McAbee Beach in Monterey County in late December when, near the surface, he spotted the undulating thing. It was some kind of ribbon fish, he wrote in a post on the Facebook group Monterey County Dive Reports. Kevin Lewand solved the mystery.
