Understanding Earthquakes and Tsunamis

The video explains the occurrence of natural disasters like earthquakes and tsunamis, focusing on the Earth's internal structure and the theory of plate tectonics. It describes how tectonic movements cause these phenomena and discusses the likelihood of such events in Brazil, highlighting the country's tectonic stability. The video concludes with suggestions for further learning.
