2004年12月26日，苏门答腊发生强烈地震，引发一系列海啸袭击泰国西南沿海地区。在这项研究中，我们调查了海啸相关的破坏模式，在穆高斯米兰海洋国家公园的珊瑚礁。结果显示，受损珊瑚占活珊瑚总覆盖面积的百分比由7.2%至39.7%不等，而在大部分研究地点，水深超过10米的珊瑚受损程度均较高。此外，巨大的平板珊瑚最容易受到海啸的破坏。调查结果亦显示，珊瑚礁的斜坡在逐渐远离海岸线的地方受到严重破坏。因此，珊瑚群落和海岸剖面可能是影响海啸产生的水流运动的主要因素，从而可能影响海啸对珊瑚的破坏模式。
On 26 December 2004, a severe earthquake in Sumatra caused a series of tsunami waves to strike southwestern coastal areas of Thailand. In this study, we investigated the patterns of tsunami-related damage to coral reefs at Mu Ko Similan Marine National Park. The results showed that the percent of damaged corals ranged from 7.2% to 39.7% of the total live coral cover, and the intensity of the coral damage was high at depths deeper than 10 metres at most study sites. In addition, massive and tabulate coral forms were the most susceptible to tsunami damage. The surveys also revealed that a high degree of coral damage occurred where the reef slope gradually dropped away from the shoreline. Therefore, coral communities and coastal profiles can be major factors influencing the movement of the currents generated by the tsunami and consequently may affect the pattern of coral damage by the tsunami.
