Devasting Tsunamis Around The World
Do you ever wonder?
How do tsunamis generate?
Tsunamis generate through displacement of water in oceans or lakes, but they are most commonly to generate by tectonic plates below the ocean floor, during Earthquakes. But, also by Volcanic Eruptions, Glacier Carving, meteoric impact or landslides. The Earth's lithosphere is separated into a bunch of discrete pieces, called plates, that move around the surface of Earth. This motion is driven by the flow of the mantle rock underneath the plates and by the forces plates exert at their boundaries where they move against each other. There are three distinct types of plate boundaries. First, there are transform boundaries. Transform boundaries slide past each other. Next, there are divergent boundaries. Divergent boundaries plates move away from each other. Last but not least, there are convergent boundaries. Convergent boundaries move towards each other.
