This eruption, with a volcanic explosivity index (VEI) of 7, ejected 37–45 km 3 (8.9–10.8 cubic miles) of dense-rock equivalent (DRE) material into the atmosphere, [3] and was the most recent confirmed VEI-7 eruption. [4] Although the Mount Tambora eruption reached a violent climax on 10 April 1815, [5] increased steaming and small phreatic ...
The 1815 Tambora eruption is the largest and most devastating observed eruption in recorded history; a comparison with other major eruptions is listed below. [ 5 ] [ 31 ] [ 38 ] 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 ...
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.
Scientists believed that the eruption affected the climate. [5] Stratovolcano St Helens 1800 United States 1 5 It began the Goat Rocks eruptive period and the continuous eruptions were relieved until the 1850s. [17] Stratovolcano: Tambora: 10 April 1815 Indonesia 2 7 This was the world's greatest eruption since the end of the ice age. [18]
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.
Two of the four eruptions were previously identified: Mount Tambora in Indonesia exploded in 1815, and Cosegüina erupted in Nicaragua in 1835. The volcano that produced the 1808/1809 eruption ...
The 1815 eruption is rated 7 on the volcanic explosivity index, the only such eruption since the Lake Taupo eruption in about 180 AD. With an estimated ejecta volume of 160 cubic kilometers, 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).
