The shoreline of Gujarat in western coast of India has remained exposed to tsunamis and storm surges in past from distant to regional sources and processes. The catalogue of past tsunami and storm events whose geological signatures have been archived in the coastal records, often hints at frequency, magnitude and recurrence. In present work, we compile all possible signatures of palaeo-extreme wave events and attempt to assess the vulnerability to this rapidly developing shoreline. We report a total of six major extreme wave events, out of which atleast two have been identified to be associated with palaeotsunami deposits, whereas three are storm surge deposits and one is designated as a washover deposit. Archeological findings like the presence of thick walls around Dholavira (an ancient Harappan coastal trading centre) is also supportive of Harappan learning from the wrath of marine waves they would have faced. This study reports the wider time gap between the events, attributed to lack of preservation, difficulty in recognition, higher reworking or lack of detailed investigation ~ making the task of estimating recurrence a mammoth effort. The study shows that the shoreline of Gujarat has remained vulnerable to extreme wave events atleast during the last 6000 years, and have affected ancient settlers as well as modern anthropological activities.

过去，印度西海岸的古吉拉特邦海岸线一直受到海啸和风暴潮的影响，这些海啸和风暴潮来自遥远的区域来源和过程。过去海啸和风暴事件的目录，其地质特征已存档在沿海记录中，通常暗示频率、强度和复发。在目前的工作中，我们汇编了古极端波浪事件的所有可能特征，并试图评估这条快速发展的海岸线的脆弱性。我们总共报告了六次主要的极端波浪事件，其中至少有两个被确定与古海啸沉积物有关，而三个是风暴潮沉积物，一个被指定为冲刷沉积物。考古发现，如 Dholavira（一个古老的哈拉帕沿海贸易中心）周围的厚墙的存在，也支持哈拉帕从他们将面临的海浪的愤怒中学习。这项研究报告了事件之间更广泛的时间间隔，归因于缺乏保存、难以识别、更高的返工或缺乏详细调查~使得估计复发的任务成为一项艰巨的任务。研究表明，至少在过去的 6000 年里，古吉拉特邦的海岸线仍然容易受到极端波浪事件的影响，并影响了古代定居者和现代人类学活动。更高的返工或缺乏详细调查〜使估计复发的任务成为一项艰巨的任务。研究表明，至少在过去的 6000 年里，古吉拉特邦的海岸线仍然容易受到极端波浪事件的影响，并影响了古代定居者和现代人类学活动。更高的返工或缺乏详细调查〜使估计复发的任务成为一项艰巨的任务。研究表明，至少在过去的 6000 年里，古吉拉特邦的海岸线仍然容易受到极端波浪事件的影响，并影响了古代定居者和现代人类学活动。
