Tectonic Forces and Catastrophes in the Ring of Fire

The video discusses the significant seismic and volcanic activities in the Ring of Fire, a region where tectonic plates meet. It highlights the 1960 Chile earthquake, the largest recorded, and explains how tectonic movements, especially at subduction and transform boundaries, lead to earthquakes and volcanic eruptions. The Ring of Fire is a major zone for these activities due to the abundance of magma and plate interactions.
