“…Tsunamis leave behind a distinctive sedimentary record that can provide critical insights into past events. These deposits can be used to reconstruct the frequency and magnitude of past tsunamis, thus informing risk assessments [2,13,14].…”

“…While wind waves break and dissipate their energy at the shoreline, tsunamis undergo wave shoaling, increasing their amplitude dramatically. A tsunami's energy can inundate the land, causing flooding and destruction far beyond the immediate coastline [5,13]. Understanding these differences is crucial for effective tsunami hazard assessment and mitigation.…”

Tsunamis, commonly induced by undersea earthquakes, are formidable natural hazards capable of causing widespread devastation. This comprehensive chapter examines the complex dynamics of tsunamis, their generation mechanisms, and their broad-reaching impacts. The multifaceted nature of tsunami triggers, both seismic and non-seismic, is dissected, highlighting the role of undersea earthquakes, landslides, volcanic eruptions, and meteorological events in driving these devastating natural phenomena. The intricate interplay of seismic parameters such as magnitude, depth, and activity type is elaborated, underscored by an insightful case study on the 2011 Tohoku Earthquake and Tsunami. A pivotal part of the discussion lies in the exploration of non-seismic triggers of tsunamis, an area often overshadowed in tsunami studies. The impact of landslide-induced and volcanically triggered tsunamis is considered alongside the contentious topic of meteorologically influenced tsunami events. Delving further into the genesis of tsunamis, the chapter explores the influences of bathymetry and tectonic structures, particularly in the context of non-seismic tsunami generation. The chapter serves as a beacon for continuous research and predictive modeling in the field of tsunami studies, emphasizing the necessity for societal preparedness and strategic risk mitigation against these potent natural disasters.
