The Tonga eruption in January was “basically like Krakatoa 2.” This time, geophysicists could explain the tiny tsunamis that cropped up all over the planet, solving a 139-year-old mystery about Tonga’s predecessor.

Deep in the mantle, a branching plume of intensely hot material appears to be the engine powering vast volcanic activity.

Scientists have begun to decipher the subtle signs that reveal how explosive a volcanic eruption is going to be.

The new volcanic fissures are more otherworldly than they first appear.

New data indicating that Earth’s surface broke up about 3.2 billion years ago helps clarify how plate tectonics drove the evolution of complex life.

The paleontologist Pincelli Hull has nailed down the timing and speed of the extinction that killed off the dinosaurs — details that carry ominous warnings for today.

A study has cemented the link between an intense global warming episode 56 million years ago and volcanism in the North Atlantic, with implications for modern climate change.

Giant blobs nestled deep in the Earth may influence everything from the structure of island chains to mass-extinction events.

Rosaly Lopes has visited dozens of active volcanoes on Earth and discovered even more elsewhere in the solar system. Her work is helping to establish whether volcanoes on distant moons could create conditions friendly to life.
