A new study explains why even gas-rich, supposedly explosive volcanoes sometimes erupt quietly instead of blowing apart.

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 ...

The explosive power and content of a volcanic eruption are determined by two key factors: the viscosity of the magma and its ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles ...

A recent volcanic eruption of the Hayli Hubbi Volcano in Ethiopia, which was dormant for over 12000 years, occurred. The huge ...

Volcanoes often look deceptively quiet until the moment they unleash towering plumes of ash and gas, yet the precise switch that turns a gentle rumble into a devastating blast has remained stubbornly ...

Sunday marked the first official record of the Hayli Gubbi volcano, in Ethiopia's remote Danakil region, erupting.

The volcano, situated in Ethiopia's Erta Ale Range, last erupted around 10,000 to 12,000 years ago. The explosive eruption ...

Scientists have discovered that shear forces inside rising magma can create gas bubbles long before pressure drops occur. The ...

MANILA, Philippines (AP) — A restive volcano in central Philippines briefly erupted Tuesday, spewing a 4.5-kilometer (2.8-mile) ash plume and debris into the sky as its rumblings were heard nearby.
