Far beneath the forests and hot springs of the American West, the continent’s largest active volcanic system is rumbling in ...

Hidden beneath the placid surface of a Siberian lake, a robot has mapped a landscape that looks more like an alien seabed than a freshwater basin. By tracing plumes of gas and reshaped sediments, ...

A high-altitude mass of volcanic ash and fumes from the Sunday morning eruption of the Hayli Gubbi volcano in northern Ethiopia is moving east - at speeds up to 120 km/hour - and reached Delhi this ...

A stream of bubbles discovered seeping from an underwater volcano has sparked a worrying prediction. Scientists warn their investigation has widespread implications for Australia’s most famous tourist ...

A long-inactive volcano in northern Ethiopia unexpectedly erupted on Sunday, sending up plumes of volcanic ash and dust, which have since spread across continents and disrupted flights in India and ...

A volcano in Ethiopia erupted for the first time in nearly 12,000 years, sending clouds of thick smoke 14 kilometres into the sky and over the Red Sea. Satellite imagery captured by NASA shows the ...

A long-quiet volcano in Ethiopia spewed ash nine miles into the sky on Sunday, marking the first known major eruption from this volcano for more than 12,000 years. Under-studied and situated in ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” ...

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 ...
