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.
A high volcanic cone with a single central vent formed before the 1815 eruption, which follows a stratovolcano shape. [18] The diameter at the base is 60 kilometres (37 mi). [8] The volcano frequently erupted lava, which descended over steep slopes. [18] Tambora has produced trachybasalt and trachyandesite rocks which are rich in potassium.
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]

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).
Tambora is a lost village and culture on Sumbawa Island buried by volcanic ash and pyroclastic flows from the massive 1815 eruption of Mount Tambora. The village had about 10,000 residents. The village had about 10,000 residents.
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 ...
