P217 SEISMIC PROCESSING IN THE PRESENCE OF ROUGH TOPOGRAPHY AND IGNEOUS ROCKS IN COLOMBIAN ANDES Abstract 1 Seismic data from a complex area in Colombia which includes igneous rock outcrops illustrate some shortcomings of the seismic method. Noise and near surface effects related to factors such as rough topography high velocities near the surface and weathering should be overcome before searching for an appropriate velocity field. In this example despite applying reasonable statics corrections and making great efforts towards noise attenuation velocity analysis is still difficult since it is hard to identify reliable reflections.
