More than 90% of the world’s pink diamonds came from a single mine that closed in 2020. Geologists are only now beginning to understand the forces that create the rare, highly prized gems.
For some people, it’s a choice based on cultural beliefs or economic opportunities provided by the volcano. Other times it’s less a choice than the only option.
Medieval monks recorded hundreds of lunar eclipses. Centuries later, their descriptions are helping scientists unravel the role of volcanoes in historical climate change.

As continents grind across ‘hotspots’ in Earth’s mantle, we can get volcanoes erupting on the surface. Studying these can reveal much about our planet’s evolution.

During the brainstorming stage of the design process, AI-powered image generation programs can open creative doors that may have otherwise never been accessed.
From a shipwreck to ancient dunes, these researchers created 3D visualisations of seafloor features around Australia – from as shallow as 22 metres to depths of over 4.8 kilometres.

Starting at the surface, you would have to dig nearly 2,000 miles before reaching the Earth’s core. No one could survive that trip – and the 10,000-degree F heat once there would vaporize you anyway.

It’s very important for tourists to understand the risks of visiting volcanic sites and properly prepare themselves for excursions to see volcanic eruptions.

When mud, fluids and gases erupt at the Earth’s surface, they hint at what’s happening underground, allowing scientists to build a more comprehensive 3D view of what’s going on inside our planet.

A scientist who led one of the first projects to map the Hawaiian Islands’ deep volcanic plumbing explains what’s going on under the surface as Mauna Loa erupts.
Mayotte’s surrounding coral reef is made up of three different structures more than 350 kilometers long. The lagoon they form is threatened by climate change and erosion.

Mayotte is no exception to the adage “small islands, big problems”. A newly born volcano combined with poor land management and accelerating climate change has put its fabled lagoon at risk.
