A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. The researchers derived a new equation that ...

Dispersive shock waves (DSWs) represent a class of nonlinear wave phenomena in which phase dispersion, rather than viscosity or dissipation, governs the evolution of abrupt changes in a medium.

Photo of a merchant ship taken in the Bay of Biscay off France, circa 1940. Huge waves are common near the Bay of Biscay's 100-fathom line. Published in Fall 1993 issue of Mariner's Weather Log.

The Peregrine soliton — a wave localized in both space and time — is now observed experimentally for the first time by using femtosecond pulses in an optical fibre. The results give some ...
