Because surface waves spread in only two dimensions ... responsible for most of the stress and damage—called a leaky Rayleigh wave—propagates much faster than a second type of wave called ...

They travel only along the surface of the Earth. There are two types of surface waves: Love and Rayleigh waves. Sponsored Love waves move back and forth horizontally. Rayleigh waves cause both ...

So-called Rayleigh–Bloch waves can release an enormous amount of energy that can damage technical systems under certain circumstances. They only exist below a precisely defined cut-off frequency ...

The path of the surface waves can be made into an arc that directs the waves outside the protective cloak. The technique could be applied to buildings by installing the rings into foundations.

A mysterious signal came minutes before the underwater Hunga Tonga-Hunga Ha'apai volcano erupted in the Pacific Ocean. But, it was missed. A new study published in Geophysical Research Letters ...
