Tsunamis waves generated by landslides are simulated in the present work using a 3D Smoothed Particle Hydrodynamics (SPH) numerical model. Some improvements, able to enhance the numerical model stability and accuracy, are presented here. An experimental study on tsunamis waves generation due to a rigid body sliding down an inclined ramp is here considered. The 3D-SPH model shows a good agreement between observed water level oscillations and simulated ones, thus demonstrating the model's ability in the study of flow fields generated by impacts of bodies with the water. The application of the implemented numerical model to a real case tsunamis event is finally presented.
