Abstract
Based on the linear long wave theory, theoretical solution is obtained for the tsunami which propagates from a tsunami source generated on a straight beach with an uniform slope. The solution indicates that the behaviors of tsunami generated on a shelf is governed by the conditions of tsunami source and that edge wave is generated considerably in the case when the tsunami source locates near a coastline. The empirical formulas are derived which evaluate the characteristics of tsunami by those of tsunami source such as the lengths of long-axis and short-axis, the position and direction of tsunami source, and so on. Further, effect of the Colioris force is also discussed.
