Seismic wave propagation in porous media is a multifaceted phenomenon where elastic waves traverse rock matrices hosting fluids within their interconnected pores and fractures. This interplay between ...

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 ...

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 ...

For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface ...

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 ...
