Abstract | The great Sumatra-Andaman earthquake of December 26, 2004, was an event of stunning proportion. The sudden rupture of a huge fault beneath the Indian Ocean unleashed the devastating Tsunami resulting from the longest fault rupture ever observed and the longest duration of faulting. This event is perhaps the most destructive tsunami ever recorded, in terms of loss of lives, waves propagated throughout the Indian Ocean and reached to the shore of several countries including Thailand. Geologists' society around the world sees this event as a biggest failure of the man kind. Nobody has ever documented what had happened in the past of the Indian Ocean. The incident has also opened a great opportunity to learn about such mega-events to predict or to take preventive measures for the future generation. Among several countries of South-east Asia, Thailand was severely hit by the tsunami causing a high death toll. As tsunami inundates the coastal areas, it leaves the trace of the event in terms of sedimentation and major morphological changes. This study was carried out to analyze the hydrodynamic prope11ies of the tsunami as well as to understand the coastal damages due to the event. The coral reef platform at the Pakarang Cape, south of Thailand, was studied and the transpo1ied corals were measured and mapped in this research. The average long axes of corals were found to be nearly parallel to the shore line, which occurred due to the most energetic wave. The comparison of boulder carrying capacity of waves indicate that more than 20m storm generated wave height is required to transport such corals, while eye witness and former surveys indicates that the maximum wave height during tsunami was 11 m at the study area. Existing boulder transport equations need further modification to obtain a more representative result. |
