Examples
- The velocity ratio or poisson ratio variaton can be obtained by comparing pn and sn velocities . 3 , in comparing pn and sn velocity variation with geology , we will find that high velocity regions always exist in old stable basin and terra , but low velocity regions lie in active extensional basin , volcano area and magmatic rock regions
