Structured and organized version of the information:Tsunami: Understanding the PhenomenonDefinition: A tsunami is a series of waves caused by sudden seabed movement due to:1. Earthquakes (<50m depth, ≥6.5 magnitude)2. Volcanic eruptions3. Underwater landslides4. Asteroid impactsFormation:1. Seabed displacement creates seismic waves2. Waves propagate through deep water, far from epicenter3. Speed: 500-800 km/h (deep water), decreasing to 20-30 km/h (approaching shore)Characteristics:1. Wave height: up to 30 meters2. Wave interval: 10-40 minutes3. Destructive power: sweeping away everything in pathTsunami Stages:1. Displacement: Ocean floor shifts, lowering sea level2. Wave formation: Seismic waves trigger wave propagation3. Amplification: Wave height increases as ocean floor rises4. Impact: Devastating effects on coastal areasRegions Prone to Tsunami:1. Areas with strong tectonic activityTerm: Tsunami (Japanese for "harbor wave")[tex].[/tex]
