To figure out the nature of the problem, for simplicity, twin masses moving toward each other are taken into account. Two different twin models are considered, one model includes two blocks, the other includes two slides. The interaction of near field tsunami amplitudes are discussed with different velocities, depths and distances related to masses, respectively. To define masses, two source models are assumed as the sliding and spreading blocks. This approach gives an opportunity to see the source model effect on tsunami amplitudes easily. Tsunami wave forms and tsunami peak amplitudes are presented for selected parameters. The results show that during the source process, when the velocity of masses are much faster than the velocity of tsunami, the displacements on the free surface above the source resembles the displacement of the floor. As the velocity of spreading masses approach the long wavelength tsunami velocity, the tsunami waveforms have progressively larger amplitudes. These large amplitudes are caused by wave focusing. As a result, source type is not a very effective parameter on amplitudes. The interaction of the tsunami waveforms are examined for different parameters, and also illustrated.
