The volcanic eruptions that bring diamonds to Earth’s surface are driven by ‘pillars of heat’ stretching deep inside the planet.

As they shape the Earth, volcanoes inspire and terrify humans.

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

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.

Drones can be used to collect gas samples from active volcanoes, where it is too dangerous for researchers. This data can be then used to predict the frequency and severity of eruptions.

Research has found evidence in NSW for one the most devastating series of volcanic eruptions known.
Climate change doesn’t just affect the atmosphere and the oceans, it affects the Earth’s crust as well.

Tsunamis can be generated by underwater volcanic explosions thousands of miles away. The Jan. 15 explosion in Tonga resulted in tsunami advisories for British Columbia and all along the U.S. west coast.

The eruption is akin to a weapons-grade chemical explosion, and there could be several weeks or even years of major volcanic unrest to follow.

Volcanoes might seem like nature’s incinerators, but using them to burn up trash would be dangerous and disrespectful to indigenous people who view them as sacred.
The eruption in East Java that claimed 22 lives on Saturday was likely triggered by weather conditions rather than by internal unrest inside Mount Semeru, which would have been easier to monitor.
Greenland’s conditions were once similar to those of a greenhouse. Volcanoes swelled the land, constricted seaways and gigatonnes of greenhouse gases were released into the atmosphere.
The eruption of Krakatoa in 1883 sent volcanic dust and gases circling the Earth, creating spectacular sunsets captured by artists.

The Rev. Sereno Edwards Bishop mobilized ship captains to track the extraordinary sunsets appearing around the world after Krakatau erupted in 1883.
This isn’t a painting or a stained-glass window — it’s a microscope image of light shining through the Earth’s mantle.
I look at fragments of the Earth’s mantle under a microscope to learn how fast molten rock moves from deep in the Earth to the surface. This can help us prepare for future volcanic eruptions.

The eruption prompted the evacuation of about 20,000 people, with no casualties.
4 billion years ago, the Earth was composed of a series of magma oceans hundreds of kilometres deep.
The rocks provide rare evidence of a time when Earth’s surface was a deep sea of incandescent magma.

Charges regarding last year’s fatal Whakaari/White Island eruption should not be about blame, but about improving hazard warnings and enforcement, particularly for sites with a history of eruptions.
New Zealand has several volcanic areas that remain popular tourist destinations. A new early-alert system for eruptions would help operators determine when it is safe to visit an active volcano.
