Topography of Andaman Sea Khao Lak Phuket Is. Tsunami would be propagate on shelf, after the direction was changed by characteristic topography between Phuket and north Sumatra. By the effect of topography, Tsunami height around Khao Lak would be come to higher than other coast. Sumatra Is. MPMD-2005 Jan. 15, 2005 K.HARADA, DRS, DPRI, Kyoto Univ.
