A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of ...

There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their relative speed is faster than other waves. P waves can travel through ...

For intense earthquakes, these surface waves can zip around the planet ... was also overprinted with what seemed to be the P- and S- waves of tiny tremors, explains Lomax, who spotted the faint ...

Through discussing earthquakes Ada explains the difference between primary and secondary waves; using both P waves and S waves to explain how scientists calculate the epicentre of an earthquake.

These were: P-waves, which oscillate back and forth similar to how a sound wave propagates; S-waves which oscillate up and down, perpendicular to the direction of travel; and surface waves ...

The primary area of research is air-sea interaction, including the topics of surface wave dynamics, air-sea fluxes, upper ocean turbulence, including Langmuir circulations, and the remote sensing of ...

The resulting IC uses surface acoustic waves and can image objects more than 100 feet away. We would imagine this could be helpful for other applications like 3D scanning, too. The system weighs ...
