Volcanoes and Tornadoes Knowledge Assessment

The video tutorial covers three major natural disasters: earthquakes, tornadoes, and volcanic eruptions. It explains the causes, characteristics, and impacts of each disaster. The Valdivia earthquake, Halam tornado, and Mount Tambora eruption are highlighted as significant historical events. The tutorial also discusses measurement tools like the seismograph and volcanic explosivity index.
