The following results are well known. Submarine landslides that cause tsunami may be triggered by earthquake, by volcanic eruptions and by storm waves. The velocities of submarine landslides and gravity currents are one or two orders of magnitude smaller than the velocities associated with earthquake dislocations. The Grand Banks submarine landslide had maximum velocities of 20-30 m/s along slopes of 2° The largest known volume of a submarine mass movement is about 5 × 10^3 km^3. Most landslides have occurred at slopes of 4° or less. In this paper it is investigated that the landslide water depth, the volume of a submarine mass movement, the velocity of submarine landslides and the landslide slope can change the size of tsunami generated by landslides according to the wave tank experiment using the simple example model of submarine landslides.
