The name of the largest volcanic eruption in history is the eruption of Mount Tambora, which occurred in 1815 in Indonesia. This cataclysmic event is credited with causing the "Year Without a Summer" in 1816 due to the vast amounts of ash and sulfur dioxide released into the atmosphere, leading to significant global climate anomalies. The eruption was rated as a VEI (Volcanic Explosivity Index) level of 7, making it among the most powerful eruptions recorded. The aftermath of Mount Tambora had devastating effects on local populations, agriculture, and was linked to famine in various regions. Today, it remains a significant event in volcanic studies.
