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 ...

Learn about how volcanoes are formed and the ways they erupt Chiara Maria Petrone, Roberto Scandone, and Alex Whittaker On February 20, 1943, Dionisio Pulido and his family were working in their ...

Some volcanoes, such as the Cascade volcanoes up in Washington and Oregon, are of the type called a stratovolcano. These steep volcanoes sometimes erupt explosively and other times have calmer lava ...

These ghostly hoops have been spotted above volcanic events around the world. But how they form has long been a mystery. Mount Etna—located in Catania, Italy—is one of the rare volcanoes that can blow ...

Scientists have long wondered how volcanoes formed in central Anatolia despite being far from tectonic plate borders—now they've found evidence of a hot plume of magma flowing from East Africa. Riders ...

Volcanic eruptions are perhaps nature's most terrifying display of power. Catastrophic eruptions of volcanoes like Mount Vesuvius, Krakatoa, and Mount St. Helens have gone down as some of the most ...

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped ...

Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered ...

Scientists say they've discovered a 400-mile chain of extinct and fossilized volcanoes beneath southern China. The volcanoes, the researchers claim, were likely formed when two major tectonic plates ...
