A unique difference was found in the scaling law of earthquake source spectra between central California and western Japan, which may be attributed to the difference in inhomogeneity length of the earth's crust. The Q of coda waves in the two regions is strongly frequency dependent with values ...

3 Chapter 3 Rayleigh Waves 3.1 Overview Waves that propagate in a medium can be roughly divided into two main categories: body waves and surface waves. Surface waves are generated only in presence of a free boundary and they can be essentially of two types: Love waves and Rayleigh waves. ...
A sub-wavelength arrangement of resonators, known as locally resonant elas- tic metamaterial7–12, allows control of waves at a deep sub-wavelength scale (λ/2 to λ/15) and can be applied to seismic waves. This concept was experimentally demonstrated for elastic plates, where13 have achieved...
