The Triangle of Tsunami Dynamics

Generation, Propagation, and Inundation

The triangle of Generation, Propagation, and Inundation explains the life cycle of tsunamis, from their creation to their impact on coastal regions. These three stages provide insight into the dynamics of these powerful natural phenomena.

1. Generation: A tsunami is generated by a sudden displacement of water, typically caused by underwater earthquakes, volcanic eruptions, or landslides. This displacement transfers energy into the water, creating waves that radiate outward across the ocean.

2. Propagation: During propagation, the tsunami waves travel across the ocean at high speeds, often exceeding 500 miles per hour in deep water. While the waves may appear small in open water, they carry immense energy over vast distances with minimal loss of power.

3. Inundation: Inundation occurs when the tsunami reaches shallow coastal areas, where the waves slow, grow in height, and flood the land. This stage causes the most destruction, impacting lives, infrastructure, and ecosystems.
