Table 1 Parameters of P-SV finite-difference modeling for the simulated models

From: Surface wave attenuation in the shallow subsurface from multichannel–multishot seismic data: a new approach for detecting fractures and lithological discontinuities

Size of grid cells 1 m
Number of cells 1600 (horizontal) × 300 (vertical)
Time interval 0.2 ms
Number of time steps 10,000
Number of absorbing grids for each side 100
  1. Note that the time interval is 0.08 ms and the number of time steps is 25,000 in the simulation for the inverted velocity model by Ikeda et al. (2013)
