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 ...

Europe’s tallest active volcano, Mount Etna, may belong to an obscure group of volcanoes shaped by magma in an unusual way.

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 ...

Located in Sicily, Mount Etna is Europe’s most active volcano. Yet its origin remains largely enigmatic, as no existing geological model fully explains how it formed. In a new study, scientists from ...

Volcanoes can behave in strikingly different ways, even when they appear nearly identical. Some release slow, steady lava ...

Geochronologists say basalt columns in Antrim sprang up during volcanic activity over 5.5m years – 8m less than thought ...

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma – and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure ...

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 ...
