Over the last century we've had about 10 tsunami per year, about one or two per year causing significant damage and/or loss of life. Given that the earth's oceans are around four billion years old we could assume that with the earth's current geological/oceanographic state there could have been around 40 billion tsunami over the history of the planet, although an earlier earth was more geologically active and early oceans were shallower (as well as much hotter in a denser atmosphere) meaning tsunami may have been much more common billions of years ago than they are now.
