Mount Tambora
It released 160 cubic kilometers    of ash into the upper atmosphere. This caused famine around the world. Tambora's 1815 outburst was the largest volcanic eruption in recorded history. It had a Volcanic Explosivity Index (VEI) of 7 and was one of the most violent eruptions in the last 5,000 years, comparable to the 180 AD "Hatepe eruption" of Taupo Volcano and the 969 AD eruption of Baekdu Mountain. The explosion was heard on Sumatra island more than  away. Heavy volcanic ash falls were observed as far away as Borneo, Sulawesi, Java and Maluku islands.
