What controls the speed of a tsunami wave?

Try this Earthlearningidea to find out what does control the speed of a tsunami wave In this activity, pupils look at the relationship between the depth of the water in the tank and the velocity of a water wave generated by lifting and then dropping one end of the tank.
One reader has sent us some comments and suggestions for this popular Earthlearningidea.
Try counting the number of waves which hit the end of the tank in both water depths shown in this video clip. Which is faster - shallow or deep water?
We shall be pleased to receive any suggestions for any of our Earthlearningideas.
