Fractional Time Derivative Seismic Wave Equation Modeling for Natural Gas Hydrate

Energies, 2020
Simulation of the seismic wave propagation in natural gas hydrate (NGH) is of great importance. To finely portray the propagation of seismic wave in NGH, attenuation properties of the earth’s medium which causes reduced amplitude and dispersion need to ...

Surface-wave imaging with nonrandom traffic seismic sourcesKey points

Earthquake Science
Passive surface wave imaging has been a powerful tool for near-surface characterization in urban areas, which extracts surface wave signals from ambient seismic noise and then estimates subsurface shear wave velocity by inversion of the measured phase ...

Seismic metasurfaces: Sub-wavelength resonators and Rayleigh wave interaction [PDF]

, 2016
We consider the canonical problem of an array of rods, which act as resonators, placed on an elastic substrate; the substrate being either a thin elastic plate or an elastic half-space.

Deriving micro- to macro-scale seismic velocities from ice-core c axis orientations [PDF]

The Cryosphere, 2018
One of the great challenges in glaciology is the ability to estimate the bulk ice anisotropy in ice sheets and glaciers, which is needed to improve our understanding of ice-sheet dynamics.
