Aaron Stanton and Mauricio Sacchi. CSEG 2015. Motivation. To migrate elastic data using elastic one way wave equation migration we first need to decompose the data into P and S potentials. This is commonly achieved by Helmholtz decomposition:. WELCOME . TO THE PRESENTATION ON THE CAMEROON SEISMIC NETWORK. PRESENTATION OF THE CAMEROON SEISMIC NETWORK . . MOUZONG PEMI MARCELIN.
