Volcanic Eruptions and Geological Processes

The video discusses two major volcanic eruptions: Mount Tambora in 1815 and Krakatoa in 1883, both located in Indonesia. Mount Tambora's eruption was the largest in history, causing widespread death and global climate effects. Krakatoa's eruption was explosive, destroying the island and causing tsunamis. Both eruptions had significant global impacts, including tsunamis and atmospheric changes. The video also explains the geological formation of these volcanoes due to tectonic plate subduction.
