Tohoku University (Japan), LPP (France), and partners has demonstrated that chorus emissions, natural electromagnetic waves ...

So far we have only considered sound in isolation and we have seen that sound has velocity, frequency, wavelength and reduces in intensity in proportion to the square of the distance from the source.

Crossplots of elastic wave velocity and resistivity can identify gas and water zones in tested formations of northwest China's Junggar basin. Crossplots of elastic wave velocity and resistivity can ...

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 ...
