When the volcano erupted in 1815, it was the most destructive volcanic eruption in modern history. It has been estimated that it was four times larger than the 1883 eruption of Krakatoa, between Java and Sumatra, in terms of volume of magma ejected. Before the explosion, Tambora was 4,300 m (14,100 ft) high, now it is only 2,722 m (8,930 ft) high. Its massive crater is therefore a caldera.
The eruption destroyed a small Asian culture, known to archaeologists as the Tamboran kingdom. It launched 100 cubic kilometers of ash into the upper atmosphere, which caused 1816 to be the "year without a summer."
Most deaths from the eruption were from starvation and disease, as the fallout ruined farming in the local region. The death toll was at least 71,000 people, of whom 11,000–12,000 were killed directly by the eruption. The often-cited figure of 92,000 people killed is believed to be overestimated.
The estimated total volume of material blown out is 160 km3 (38 cu mi). Tambora's 1815 outburst was the largest volcanic eruption in recorded history. The explosion was heard on Sumatra island more than 2,000 km (1,200 mi) away. Heavy volcanic ash falls were observed as far away as Borneo, Sulawesi, Java and Maluku islands.
The eruption caused a global climate change known as the "volcanic winter". 1816 became known as the "Year without a summer" because of the effect on North American and European weather. Crops failed and livestock died in much of the Northern Hemisphere, resulting in the worst famine of the 19th century.
