DISCUSSION ON IMPORTANCE OF ERROR IN SEISMIC ??
SURFACE WAVE INVERSION |
| |
| Abstract: | Importance of observation’s error in seismic inversion was discussed,and the seismic wave simulation data that contains error were inversed using methods of LSQR, WLSQR and MLS. The inversion results show that the effect of observation’s error is notable in seismic surface wave inversion ,and ignoring the observation’s error will greatly reduce the reliability of inversion results. |
