本文讨论了2004年12月26日海啸对印度西南海岸地貌特征和沉积物特征的影响。使用的数据包括海啸后进行的实地观测以及根据海啸前后拍摄的卫星图像得出的推论。对从内陆架、海滩和河口环境收集的沉积物样本进行分析，以了解海啸后颗粒尺寸特征的变化。海啸侵蚀了大量富含重矿物质的独特黑沙，并将其从陆架输送到喀拉拉邦地区的海滩，以及目前海岸内陆 500 米处。
This paper discusses the impact of the December 26, 2004 tsunami on the geomorphic features and sediment characteristics along the southwest coast of India. The data used include field observations made after the tsunami, and the inferences drawn from the satellite imagery taken before and after the tsunami. Sediment samples collected from the inner shelf, beach and estuarine environments were analyzed to understand post-tsunami changes in grain-size characteristics. The tsunami eroded and transported landwards significant volumes of distinct black sands, rich in heavy minerals, from the shelf onto the beaches of the Kerala region, and up to 500 m inland of the present coast.
