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

Map of the Earth showing tectonic plates. Early Earth likely had no plate tectonics, but a solid outer crust with no tectonic activity covered the entire planet. After being broken up by convection ...

Evaluation of landforms, soils, and deposits formed by active tectonics is providing basic data necessary for long-term earthquake prediction, seismic-hazard evaluation, and probabilistic seismic-risk ...

Until recently, researchers believed only one planet in our solar system had plate tectonics: Earth. But in a recent study, Brown University researchers used atmospheric modeling to show that Venus, ...

This artist’s concept of the large Quetzalpetlatl Corona located in Venus’ southern hemisphere depicts active volcanism and a subduction zone, where the foreground crust plunges into the planet’s ...

An international team has made a significant breakthrough in understanding the tectonic evolution of terrestrial planets. Using advanced numerical models, the team systematically classified for the ...

Volcanic eruptions frequently interfere with human affairs; impacts range from minor nuisances to major disasters. Some 50 to 65 different volcanoes typically are active in any given year, and among ...
