Aside from widespread casualties caused by the earthquake itself, the seismic event sent tidal waves, topping ten meters, thundering through the Indian Ocean and Andaman Sea region and battering northeastern Indonesia, Sri Lanka, southern India, southern Thailand, the Maldives, and the western part of Malaysia. The estimated death toll exceeds 280,000.
除了地震造成重大的傷亡外，隨後又引發大海嘯，超過十幾公尺的滔天巨浪一波波席捲印度洋、安達曼海沿岸地區，包括印尼東北部、斯里蘭卡、印度南部、泰國南部、馬爾地夫、馬來西亞西部等地都遭到波及，罹難人數粗估已超過二十八萬人。
