Submarine volcanoes, volcanic structures hidden beneath the ocean surface, play a vital role in shaping Earth’s geology and marine ecosystems. Formed through tectonic plate movements, rising magma, ...

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 ...

Microscopic clues in volcanic ash reveal how magma breaks apart, heals, and sticks back together during explosive eruptions.

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 ...

Mount Etna has long puzzled geologists because it doesn't fit any of the three classic ways volcanoes are thought to form. A new study suggests it may instead be fueled by ancient pockets of magma ...

Kilauea is in a unique phase of activity in Halema‘uma‘u, with 12 episodes of dual lava fountains since Dec. 23, 2024. Several past eruptions have been characterized by similar lava fountaining ...

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 dropped ...

A team of geologists led by the University of Maryland and the University of Hawaiʻi finally connected one of the largest volcanic eruptions in Earth’s history with its source deep beneath the Pacific ...

Geologists led by the University of Maryland and the University of Hawaiʻi finally connected the dots between one of the largest volcanic eruptions in Earth's history and its source deep beneath the ...
