Short summary
We present an approach for seismic hazard assessment that considers a hybrid source model composed of faults and zones containing the remaining seismicity. The seismic-moment rate is used to distribute seismic potential, avoiding double counting. The approach is applied in SE Spain, a region of low-to-moderate seismicity. Results show a concentration of expected accelerations around fault traces using the hybrid approach, which is not appreciated in the classic approach using zones exclusively.
