A study presents a broad survey of monogenetic volcanoes younger than 2.58 million years in the U.S. Southwest. They’re born. They live once, erupting for…
Geologists from the UNIGE and Peking University have developed a technique that makes it possible to estimate the maximum size of a future super-eruption of…
A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of…
Princeton researchers have solved a 54-year-old puzzle about why certain fluids strangely slow down under pressure when flowing through porous materials, such as soils and…
Heat from a comet exploding just above the ground fused the sandy soil into patches of glass stretching 75 kilometers, a study led by Brown…
While analyzing some of the world’s oldest colored gemstones, researchers from the University of Waterloo discovered carbon residue that was once ancient life, encased in…
Rather than being created solely during supernova explosions, chemical elements could also be produced deep within the Earth’s lower mantle. It has long been theorized…
Rift Valley lakes within eastern Africa range from freshwater to highly alkaline systems and are homes to diverse ecosystems. These Rift Valley lakes are also…
On Earth, river erosion is usually a slow-going process. But on Mars, massive floods from overflowing crater lakes had an outsized role in shaping the…
Newly discovered fossil human footprints embedded in an ancient lakebed show that humans inhabited North America during the Last Glacial Maximum (LGM), occupying the region…
A study published in the journal Geology rules out that extreme volcanic episodes had any influence on the massive extinction of species in the late…
A team of Lawrence Livermore National Laboratory (LLNL) researchers, in partnership with two other national laboratories, has launched a project studying the viability of large-scale…
Maharloo sits at an altitude of around 1,400 m (4,600 ft) above sea level and is located around 27 km (17 mi) southeast of Shiraz,…
Lava samples have revealed a new truth about the geological make-up of the Earth’s crust and could have implications for volcanic eruption early warning systems,…
Spectacular ice age landscapes beneath the North Sea have been discovered using 3D seismic reflection technology. Similar to MRI (magnetic resonance imaging) the images reveal…
The troughs on Vesta have long been a topic of scientific speculation. The asteroid Vesta is the second largest asteroid in our solar system. With…
Several filmmakers have used the desert landscapes of Wadi Rum as a stand-in for the Red Planet. Wadi Rum looks like few other places on…
