Mount Tambora, also called Mount Tamboro, Indonesian Gunung Tambora, volcanic mountain on the northern coast of Sumbawa island, Indonesia, that in April 1815 exploded in the largest volcanic eruption in recorded history. The trail leads mainly trough lush and beautiful rainforest up to Pos 5.… It is an exhausting hike to the summit, but not technically challenging. The volcano originally grew to about 4000 m elevation before a major explosion destroyed its summit and left a pre-1815 caldera more than 43,000 years ago. The Tambora caldera is ~1.2 kilometers deep, so the volcano lost at least a few kilometers of elevation in a matter of maybe a day. The largely trachybasaltic-to-trachyandesitic volcano grew to about 4,000 m elevation before forming a caldera more than 43,000 years ago.
