Mount Tambora is a volcano on the island of Sumbawa in present-day Indonesia, then part of the Dutch East Indies, [2] and its 1815 eruption was the most powerful volcanic eruption in recorded human history. This volcanic explosivity index (VEI) 7 eruption ejected 37–45 km 3 (8.9–10.8 cubic miles) of dense-rock equivalent (DRE) material into ...
The 1815 Tambora eruption is the largest and most devastating observed eruption in recorded history; a comparison with other major eruptions is listed below. [4] [30] [37] The explosion was heard 2,600 kilometres (1,600 mi) or 3,350 kilometres (2,080 mi) away, and ash deposits were registered at a distance of at least 1,300 kilometres (810 mi).
The main cause of the Year Without a Summer is generally held to be a volcanic winter created by the April 1815 eruption of Mount Tambora on Sumbawa. [7] [8] [9] The eruption had a volcanic explosivity index (VEI) ranking of 7, and ejected at least 37 km 3 (8.9 cu mi) of dense-rock equivalent material into the atmosphere. [10]
Three great columns of flame rose in the sky over Mount Tambora on April 10, 1815. The long-dormant Indonesian volcano had rumbled to life five days earlier with a thunderous detonation followed.

The only unambiguous VEI-7 eruption to have been directly observed in recorded history was Mount Tambora in 1815 and caused the Year Without a Summer in 1816. The Minoan eruption of Thera in the middle of the second millennium BC may have been VEI-7, but may have been just shy of the 100 cubic kilometers required.
The only semi-recent example was the 1815 eruption of Mount Tambora, which led to worldwide cooling and agricultural failures and caused 1816 to become known as the "year without a summer."
Some of the volcanoes are notable for their eruptions, for instance, Krakatoa for its global effects in 1883, [1] the Lake Toba Caldera for its supervolcanic eruption estimated to have occurred 74,000 years before present which was responsible for six years of volcanic winter, [2] and Mount Tambora for the most violent eruption in recorded ...
