  12. Survey Result http://www.drs.dpri.kyoto-u.ac.jp/sumatra/ K.HARADA, DRS, DPRI, Kyoto Univ. Thailand Group, ITST of Indian Ocean Tsunami Disaster 2004

  13. 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. K.HARADA, DRS, DPRI, Kyoto Univ.

  14. Building Damage Tsunami height = 8.8 m from sea level Roof tile are washed away by Tsunami Tsunami at Khao Lak K.HARADA, DRS, DPRI, Kyoto Univ. Thailand Group, ITST of Indian Ocean Tsunami Disaster 2004

  15. Building Damage RC Column • Wall • Stacked Bricks • Can’t resist tsunami pressure at Khao Lak K.HARADA, DRS, DPRI, Kyoto Univ. Thailand Group, ITST of Indian Ocean Tsunami Disaster 2004

  16. Tsunami Runup Tsunami height ≒9.6m Runup distance ≒300m from shoreline • Tsunami run up mountain foot • Vegetation are die down by Tsunami(salt water) at Khao Lak K.HARADA, DRS, DPRI, Kyoto Univ. Thailand Group, ITST of Indian Ocean Tsunami Disaster 2004

  17. Phi Phi Island N South North S Phi Phi Island has sandbar at central part. Ground Elevation of sandbar is very low(a few meter) and narrow. North side have sand beach and very shallow bay. South side have Pier, and water depth of south side is deeper than north side. Tsunami Tsunami K.HARADA, DRS, DPRI, Kyoto Univ. Thailand Group, ITST of Indian Ocean Tsunami Disaster 2004
