Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. They can have devastating effects on surrounding areas, especially near the coastlines of major cities. Tsunamis are often depicted in apocalyptic-style movies, such as the movie 2012.
Tsunami occurrences can lead to bringing relevance to plate tectonics, acceleration and speed in general sciences, force and motion, energy transfer, and the physics of waves as a whole! There is much to learn about these natural events, more of which can be found online!
