Similarly, P wave dispersion (increase of seismic velocity with frequency) also show higher change at 12 % gas saturation.
It is not reasonable value as it assumes that the velocity ratio of P and S waves of each medium remains the same which is not possible because seismic velocity generally increases with depth (Ma, 2004).
"Hotter plumes not only have slower seismic velocity and a higher hotspot buoyancy flux, they are the ones with the highest He-3/4.

conducted a quantitative analysis of seismic velocity tomography for rockburst hazard assessment [6].
A backprojection method is a powerful tool for locating the source of microseisms when travel time can be inferred accurately with a seismic velocity model.
The ground motion actually lasts for a long time, but most of amplitude section of seismic velocity time history has been included in the primary 30 s.
According to the existing well data, the average seismic velocity to the top of the Silurian is 2500 m/s, therefore the amplitude of the structures in the depth scale is not higher than 30-40 m.
The seismic velocity range when the sledgehammer is used varies from 165.3 to 698.1 m/s.
Based on changing seismic velocity some layers physically can be distinguished.
Furthermore, we employ effective medium [7, 9] models in order to estimate and comparatively analyze seismic velocity (or moduli) based on pore aspect ratio to characterize the appropriate pore-shape factor in the Granite Wash reservoirs.
