Abstract

Abstract: 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.
