Since silicic magmas are colder and goopier than mafic magmas, dissolved gases have a harder time venting out of them. This ...

A groundbreaking study has unveiled a fiery, subterranean process that could explain the abundance of water across the solar ...

Volcanos are releasing ash and smoke into the atmosphere on three continents. That might be making you think back to your elementary school science class when you probably studied volcanoes and lava.

The extra magma doesn’t mean it’s more likely to erupt, scientists say. In fact, the better measurement helps them to understand its future. By Robin George Andrews Magma is the explosive lifeblood of ...

Site of half the world's active geysers and about the same size as Cyprus, Yellowstone National Park's scenery and wildlife make it one of the biggest draws for tourists in the US. But those famous ...

Colour-coded topographic view shows the relative heights of features in Cerberus Fossae: reds and whites are relatively higher than blues and purples. The image is based on a digital terrain model of ...

Scientists have long assumed that, like rocky planets such as Earth, sub-Neptunes begin with molten magma oceans. Their thick hydrogen-rich atmospheres were thought to trap heat efficiently, allowing ...

Researchers traced tremor signals deep inside Tanzania’s Oldoinyo Lengai volcano, pinpointing their 3D locations for the first time. The study revealed linked tremors at different depths, offering a ...

Magma is the molten material beneath the Earth's crust. It usually collects in a magma chamber beneath a volcano, and can then be injected into cracks in rocks or issue out of volcanoes in eruptions.
