Ritual sacrifices of "sun stones" coincided with a large volcanic eruption that made the sun disappear throughout Northern Europe, research finds.

"The same types of processes that result in volcanic eruptions are processes that form gold deposits."

"This event, and events like it, are the best analogs we have in Earth's past for what is to come in the next decades and centuries."

For the first time, researchers have found frost on Mars' Tharsis volcanoes, challenging previous assumptions about the planet's climate.

Surviving a supervolcano eruption around 74,000 years ago may have facilitated human dispersal from Africa, researchers report.

When researchers reconstructed lava flows on Mars, they realized the red planet is a lot more active than they previously thought.

Climate change triggered by massive volcanic eruptions, and not a meteorite plummeting to Earth, may have led to dinosaurs' extinction.

Massive volcanic eruptions over the past 260 million years caused lethal climate change that led to mass extinctions, researchers say.

Researchers offer the first description of the animal communities around the asphalt volcanoes off the coast of Santa Barbara, California.

The Fagradalsfjall volcano in Iceland reveals a process far more dynamic than anyone had assumed in two centuries of research.
