Mercedes-Benz's squat little Unimog trucks have proven their expeditionary prowess yet again with the announcement that a U 5023 truck has set a new altitude record for wheeled vehicles, reaching 6,694 m (21,962 ft) above sea level.

A new study suggests that Venus may not be as geologically dead as we thought. Infrared spectra and laboratory work show that there may be volcanic activity on the planet, with some lava flows being only a few years old.

Volcanic islands may be scenic, but they're also short-lived by geological standards. By looking at 14 volcanic island chains, a team of MIT scientists have gained insights into why some islands last longer than others.

Fossilized shells have now revealed that Earth’s systems were already stressed before the asteroid impact that killed the dinosaurs, as volcanic eruptions may have heated the oceans and raised mercury levels to dangerous heights.

Despite raising the alert level weeks prior to the devastating events of Monday, the violent eruption on White Island was not one authorities were able to predict with any precision, owing to the type of delicate, steam-driven processes that led to its explosion.

The annual Nature Conservancy Photo Contest shows off some truly astonishing perspectives on our natural world, from erupting volcanos to peaceful landscapes.

A huge raft of volcanic rock is floating towards Australia – and scientists say it'll help the ailing Great Barrier Reef.

Many of us will know what bubbling lakes of lava within volcanoes look like. After all, we've seen them our entire lives in movies and on TV. But that doesn't mean they're common. In fact, only seven lava lakes have been found so far, until now.

A team of volcanologists at the University of Missouri turned fashion models recently as they showed off prototype lava suits that are designed as comfortable, hard-wearing field outfits for scientists bound for the slopes of Vesuvius and the like.

Last year a huge lake of liquid water was apparently found beneath the ice at the Martian south pole. A new study has now examined how it might have gotten there, and concluded that Mars must have had volcanic activity much more recently than is normally believed, and may even still be active today.

​Would you want to climb up an active volcano to deposit a sensor at its crater? Probably not, and it's something that safety-conscious volcanologists would prefer not to do, too. With that in mind, British scientists have created drone-deployed sensing devices known as "dragon eggs."

The unusually cold year of 1816 has been linked to one of the most powerful volcanic eruptions in recorded history, and now we may know how. A new paper explains how electrified ash from the eruption could have “short-circuited” the Earth’s ionosphere and triggered the “Year Without A Summer.”
