Özet

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) over bar /c(T) > 5, where (c) over bar is average velocity of the slide and c(T) = rootgh 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) over bar /c(T) less than or equal to 5, especially when (c) over bar /c(T) similar to 1.
