Earthquake Waves and Tectonic Movements

The video tutorial provides an overview of earthquakes, explaining their causes, key terminology, and the types of seismic waves. It covers the release of energy during tectonic plate movements, leading to earthquakes, and introduces terms like focus and epicenter. The tutorial details the characteristics of body and surface waves, including P, S, L, and R waves, and their impact on the Earth's surface. The video concludes with a call to action for viewers to subscribe.
