A BRIEF summary of the salient features of the stratigraphy of the Commonwealth is essential for understanding its tectonic structure. Pre-Cambrian rocks are developed in Western, Central, and ...

A tectonic plate is a massive slab of Earth’s outer shell, known as the lithosphere. These plates float on the asthenosphere, a softer, more flexible upper mantle layer. Earth’s lithosphere is ...

A new study published in Science Advances has revealed the first detailed images of a newly developing subduction zone off ...

Plate tectonics: Earthquakes. Download/print a transcript of this episode (pdf). This video explores the structure of the Earth and how the lithosphere is split into seven major plates and many ...

Structure and tectonics advances most clearly when multiple approaches are focused on the problems at hand, a point made by the frequent collaborations between faculty and graduate students in this ...

"This has profound implications for how we interpret surface volcanism, earthquake activity and the process of continental ...

This study won’t end the debate over Venus’ tectonic structure, but the team was able to “recognize that there was a bigger picture pattern,” Herrick says.

Europe and North America, once considered fully separate continents, may still be part of the same tectonic structure. That would leave just six true continents on Earth, ...

A 4.4 magnitude earthquake struck Delhi on Thursday, reigniting concerns about the city's seismic vulnerability. Located in high-risk Seismic Zone IV, Delhi is prone to moderate-to-strong quakes due ...
