A modified EOM method is developed for PS-wave migration based on the equivalent offset migration (EOM) for P-waves. This gives better imaging quality than the previous EOM methods by reducing errors from the discretisation of equivalent offsets and suppressing noise from the co-location of source-receiver. An equivalent PS-wave velocity is also introduced. Processing real 2-dimensional 3-component seismic data shows that the method can produce a better migrated image than the conventional common conversion point (CCP) method.
