Understanding Earthquakes

The video explains earthquakes, starting with a humorous introduction. It describes the Earth's surface as tectonic plates that move slowly, causing earthquakes when they collide or slide past each other. The video covers the concepts of faults, hypocentres, and epicenters, and explains the three types of earthquakes: convergent, divergent, and transform. It reassures viewers that most earthquakes are too small to feel, but some can be powerful. The video also discusses how earthquakes are measured using a seismograph and mentions tsunamis caused by underwater earthquakes.
