✦ Synopsis

In this study, the motion of a submarine block slide, with variable velocities, and its effects on the near-field tsunami amplitudes are investigated. The numerical results show that the amplitudes generated by the slide are almost the same as those created by its average velocity when c c=c T > 5, where c c is average velocity of the slide and c T ¼ ffiffiffiffiffi gh p is the long period tsunami velocity in ocean of constant depth h. In contrast, the kinematic model of the slide must take into account time variations in the moving velocity, if c c=c T 5, especially when c c=c T $ 1.
