Mt. Tambora;
Mount Tambora is located on the north and south of the oceanic crust. Tambora is formed by the subduction zone beneath it. This increases the height of Tambora to 4,300 m which makes this mountain once one of the highest peaks in the archipelago and dries up the huge magma kitchen inside this mountain. It took a century to refill the magma kitchen.
During the archaeological excavations of 2004, the team of archaeologists discovered the remains of a culture buried by an 1815 eruption at a depth of 3 meters in pyroclastic deposits. The artifacts were found in the same position when the eruption occurred in 1815. Because of these similar characteristics, the findings are often referred to as Pompeii from the east.
As a result of the 1815 eruption, Mount Tambora formed the largest dry caldera in Indonesia and its height decreased from about 4,000 meters to 2,850 meters up to now.

History of eruption;
  • 1812; the Tambora mountain caldera begins to rumble and produce black clouds. Stothers, Richard B. (1984)
  • 1815, 5 April; The eruption occurred, followed by the sound of thunder heard in Makassar, Sulawesi (380 km from Mount Tambora), Batavia (now Jakarta) on the island of Java (1,260 km from Mount Tambora), and Ternate in Maluku (1400 km from Mount Tambora). The sound of thunder was heard up to the island of Sumatra on 10-11 April 1815 (more than 2,600 km from Mount Tambora) which was originally regarded as a gunshot sound. The eruption entered on a scale of seven on the scale of the Volcanic Explosivity Index. This eruption is four times stronger than the eruption of Krakatoa in 1883. Raffles, S. (1830)
  • 1819; …
  • 1847-1913; eruption occurs inside the caldera that menghreamkan leleran lava and the formation of Doro Api Toi crater
  • 1913-present; activities limited to fumarola and solfatara ..

Topology & Geology;
Which develops in Mount Tambora and around, ie in the form of cesareous structure, alignment of volcanic, caldera structure and crater structure. The normal faecal type (normal faults of Tambora), found around the summit of Tambora Mountain, north-northeast north-south-west, affects the ridge’s morphological maturity in the south-southwest of Mount Tambora; Bili faults, east-west trending, affects the morphological ecology of the southeastern ridge of the Kawindana Toi caldera; The Kukinding Nae-Nangamire-Sotonda Kukinding alignment is manifested by the appearance of three cones (Kadinding Nae, Nangamire and Satonda) located on a straight line directed almost north-south; The alignment of Gubu Panda, northwest-southeast direction, is predicted to be closely related to the appearance of the Gubu Panda cone and the morphological shape of the northern Tambora slope, especially in the boundary areas with the old morphology of Kawindana Toi; The caldera structure (Tambora Caldera is 6×7 km in diameter and Kawindana Toi Caldera leads to the northeast, horseshoe-shaped); The structure of the crater, commonly found on the small outer fringes scattered throughout the lower slopes and the foot of Mount Tambora, are: Kadinding Nae Crater, Nangamire, Satonda, Gubu Panda, Doro Peti, Doro MBoha, Doro Ncanga, Doro MBente and Doro Tabeh / Doro Twins.
