Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and upper mantle that fit together like puzzle pieces. Think of these plates as massive rafts floating ...

This makes Etna an enigma. Despite its long historical record – plus extensive monitoring and research in modern times – no ...

New research suggests Mount Etna forms from deep mantle magma pockets, possibly classifying it as a rare “petit-spot” volcano ...

Volcanoes are Earth’s geologic architects. They’ve created more than 80 percent of our planet’s surface, laying the foundation that has allowed life to thrive. Their explosive force crafts mountains ...

Some volcanoes, such as the Cascade volcanoes up in Washington and Oregon, are of the type called a stratovolcano. These steep volcanoes sometimes erupt explosively and other times have calmer lava ...

Some scientists think we can better understand volcanoes by learning how the gaseous vortexes emerge. By Carolyn Wilke Some volcanoes perform a rather subtle trick: blowing rings of vapor that waft ...

Deadliest volcanic eruption: The 1815 eruption of Mount Tambora in Indonesia, which killed up to 100,000 people From lava fountains to towering ash clouds, volcanoes produce some of the most dramatic ...

Learn how Mount Etna stands apart from most volcanoes, having been formed by pockets of magma held in Earth's upper mantle.

How did young volcanoes on Mars form? This is what a recent study published in the journal Geology hopes to address as a team of scientists investigated the complex geological processes responsible ...

Learn how scientists discovered that Methana, a volcano in Greece believed to be dormant, was actually collecting magma for ...
