Looks like a trick question to me, unless you have more info. Volume is 3-dimensional space. You only have height and (what I would take to be unnecessary) speed. Unless you have width (how many miles wide is the tsunami?) and depth (how far from the front of the tsunami to the back?) I'm not totally sure you can solve it.
