The film discusses the science of earthquakes, focusing on a significant earthquake recorded in Berkeley, California, that originated in Eastern Turkey. It explains how seismographs detect seismic ...

BUTTE, Mont. — Envision this scenario: You are going about your day. All is calm and quiet until suddenly, the ground beneath your feet begins to shake, and items within your home or workspace begin ...

Over a thousand miles from the surface, in Earth’s D” layer—right on the edge of the liquid metal outer core—there is a weird acceleration of seismic waves. Experiments recreating the phenomenon in a ...

A research team led by Prof. ZHANG Haijiang from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, and Prof. HOU Zengqian from Chinese Academy of Geological ...

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 ...

As oceans waves rise and fall, they apply forces to the sea floor below and generate seismic waves. These seismic waves are so powerful and widespread that they show up as a steady thrum on ...

Mars may have a hardened heart. Marsquake reverberations detected by NASA’s InSight lander revealed that the Red Planet probably possesses a solid inner core, researchers report in the Sept. 4 Nature.

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 ...
