印度洋是全球受海啸威胁最严重的区域之一，历史上的多次海啸事件造成了重大的人员伤亡和经济损失。建设有效的海啸预警系统，对提升该区域的防灾减灾能力至关重要。本文首先回顾印度洋区域得历史海啸事件及其影响，并深入分析了三次典型事件，探讨了海啸生成与构造背景的关系。特别地，我们讨论了地震、海底滑波、火山活动三种主要的海啸生成机制，以及它们各自的特点和相互作用。此外，本文提出利用T波进行海啸预警的可能性，并评估了这种方法的可行性，为未来印度洋区域实施更高效的海啸预警提供了新的思路。本文研究将提升科学界对印度洋区域海啸灾害与海啸预警新方案的关注，服务于我国“一带一路”战略。

The Indian Ocean is one of the most tsunami-prone regions in the world. Multiple historical tsunami events have resulted in significant loss of life and economic damage. Establishing effective tsunami early warning systems is crucial for enhancing disaster prevention and mitigation capabilities in this region. This paper begins by reviewing historical tsunami events in the Indian Ocean and their impacts, followed by an in-depth analysis of three typical cases to explore the relationship between tsunami generation and tectonic settings. Specifically, we discuss the three primary tsunami generation mechanisms—earthquakes, submarine landslides, and volcanic activities—and analyze their characteristics and potential interactions. Additionally, we propose the potential use of T-waves for tsunami monitoring and evaluate the feasibility of this method, providing new insights into more efficient tsunami early warning strategies for the Indian Ocean region. Our study aims to increase scientific attention on tsunami hazards and innovative early warning solutions in the Indian Ocean, contributing to China's "Belt and Road" initiative.
