Comparison of FD and FDFE for topography model:

model 00 : vp=2000, vs=0.01 m/s, vp/vs= infinity ( formal ' liquid ridge ' )

model 01 : vp=2000,  vs=200 m/s, vp/vs= 10

model 02 : vp=2000,  vs=300 m/s, vp/vs= 6.7

model 03 : vp=2000,  vs=500 m/s, vp/vs= 4

model 04 : vp=2000,  vs=750 m/s, vp/vs= 2.7

model 05 : vp=2000, vs=1000 m/s, vp/vs= 2

model 06 : vp=2000, vs=1153 m/s, vp/vs= 1.73 ( =SQRT(3) )

model 07 : vp=2000, vs=1400 m/s, vp/vs= 1.42 ( This is just formal, not physical value of ratio ! )

The results of FDFE (finite-element finite-differences) hybrid method of Moczo et al. (1997) for the ridge model were kindly provided by J. Kristek (Geophys. Inst., Slovak Academy of Sciences, Bratislava, Slovakia).

The computed data, postscript figures, explanation, etc. are available free ON DEMAND
