Researchers have mathematically elucidated how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. A novel equation was derived to describe the travel of ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

Geophysicists find link between seismic waves called PKP precursors and anomalies in Earth's mantle that are associated with hotspots associated with volcanism on the surface. For the decades since ...

Some earthquakes are imperceptibly quiet. We may not feel them, but machines might detect them—and they can point scientists to a potential "Big One". Geophysicist Zachary Ross is pioneering a new way ...
