"WebThe term ‘tsunami’ (harbour wave) comes from Japan where the phenomenon frequently occurs. When an underwater quake or any other cause suddenly sets a great depth of water into motion, it causes a gigantic wave to form. In the open sea, the undulation cannot be seen. However, when it hits shore, its height increases, submerging the coastline and … " - Tsunami wave propagation

Tsunami – interactive simulations – eduMedia

A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, … WebThis monograph aims at presenting a unified approach to numerical modeling of tsunami as long waves based on finite difference methods for 1D, 2D and 3D generation processes, propagation, and runup. Many practical examples give insight into the relationship between long wave physics and numerical solutions and allow readers to quickly pursue ...
