For decades, volcanologists believed that the primary trigger for explosive eruptions was a drop in pressure as magma rises ...

Learn how stress inside a volcano can make gas bubbles form early, helping explain why some eruptions stay quiet instead of exploding.

Scientists have discovered that shear forces inside rising magma can create gas bubbles long before pressure drops occur. The intensity of a volcanic eruption is shaped by how many gas bubbles develop ...

Magma is the molten rock that is present beneath the surface of the Earth, while lava is the one that comes out to the Earth’s surface in case of a volcanic eruption. Check the difference between ...

Kilauea is one of the most active volcanoes in the world with eruptions common both at its summit caldera and within its two rift zones. Frequent earthquakes associated with volcanic activity can help ...

Discover why volcanoes erupt, how magma and gases cause eruptions and why volcanoes are essential for life on Earth.

In a new study, researchers show that gas bubbles can form in the rising magma not only due to a drop in pressure but also due to shear forces. If these gas bubbles grow in the volcanic vent early on ...

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

HONOLULU (AP) — The on-and-off eruption that’s been dazzling residents and visitors on Hawaii’s Big Island for nearly a year resumed Tuesday as Kilauea volcano sent fountains of lava soaring 400 feet ...
