Exploring the Mechanics of Earthquakes

The video explains earthquakes, their causes, and effects. It covers tectonic plates, seismic waves, and the Richter scale. Historical earthquakes are discussed, and a simulation demonstrates different magnitudes' impacts. The video also explores challenges in predicting earthquakes and introduces tools like seismographs and smartphone apps. It concludes with safety tips and resources for further learning.
