The cone-convex hull by complement (ccc-hull) is a generalized convex hull created from Poincare Cones. We propose a new approach with the ccc-hull for the simulation of the extent of damage by a tsunami, and simulate the damaged area at the time of the Great East Japan Earthquake for approximate damage by samples from a twodimensional Non-homogeneous Poisson Process. Then, we consider the problem of the estimation of the parameter, which corresponds to the opening angle of the Poincare Cones. We believe our suggestion can be used to predict the extent of a tsunami in a specified area in Japan.
