Earthquake Effects and Causes

The video explores the fascinating and terrifying nature of earthquakes, their origins, and their profound effects on the environment, landscapes, and climate. It discusses how earthquakes occur due to tectonic plate movements and their potential to cause tsunamis and volcanic eruptions. The video also highlights peculiar phenomena like sand volcanoes and liquefaction, and modern threats such as risks to nuclear power plants. Understanding earthquakes is crucial for building resilient communities and preparing for future geological events.
