Volcanoes are Earth’s geologic architects. They’ve created more than 80 percent of our planet’s surface, laying the foundation that has allowed life to thrive. Their explosive force crafts mountains ...

How did young volcanoes on Mars form? This is what a recent study published in the journal Geology hopes to address as a team of scientists investigated the complex geological processes responsible ...

Some scientists think we can better understand volcanoes by learning how the gaseous vortexes emerge. By Carolyn Wilke Some volcanoes perform a rather subtle trick: blowing rings of vapor that waft ...

Olympus Mons, a shield volcano on Mars, is the largest volcano in the solar system, measuring approximately 370 miles in diameter and 26 kilometers in height. The formation of Olympus Mons and three ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

Add Yahoo as a preferred source to see more of our stories on Google. Have no fear: this won't happen in New England any time soon as there are currently no active volcanoes in the region. But ...

Kilauea in Hawai’i has been in a state of near-constant eruption for decades, providing researchers with a uniquely reliable setting to study one of our planet’s most unpredictable and destructive ...
