Abstract
The effects of variable speeds of spreading of submarine slides and slumps on near-field tsunami amplitudes are illustrated. It is shown that kinematic models of submarine slides and slumps must consider time variations in the spreading velocities, when these velocities are less than about 2cT, where cT = √gh is the long period tsunami velocity in ocean of constant depth h. For average spreading velocities greater than ~2cT, kinematic models with assumed constant spreading velocities provide good approximation for the tsunami amplitudes above the source.
