Mount Tambora (or Tamboro) is an active stratovolcano which is a peninsula of the island of Sumbawa in Indonesia. Sumbawa is flanked both to the north and south by oceanic crust, and Tambora was formed by the active subduction zone beneath it. This raised Mount Tambora as high as 4,300 m (14,100 ft),[4] making it one of the tallest peaks in the Indonesian archipelago in the 18th century. After a large magma chamber inside the mountain filled over the course of several decades, volcanic activity reached a historic climax in the eruption of 10 April 1815. This eruption was about a volcanic explosivity index (VEI) of 7, the only unambiguously confirmed VEI-7 eruption since the Lake Taupo eruption in about AD 180.[6] (The Heaven Lake eruption of Baekdu Mountain around AD 969 might have also have been VEI-7.) With an estimated ejecta volume of 160 km3 (38 cu mi), Tambora's 1815 outburst is the largest volcanic eruption in recorded history.

The explosion was heard on Sumatra, more than 2,000 km (1,200 mi) away. Heavy volcanic ash falls were observed as far away as Borneo, Sulawesi, Java, and the Maluku Islands. Most of the deaths from the eruption were from starvation and disease, as the eruptive fallout ruined agricultural productivity in the local region. The death toll was at least 71,000 people, of whom 11,000–12,000 were killed directly by the eruption; the oft-cited figure of 92,000 people killed is believed to be an overestimate. The eruption caused global climate anomalies that included the phenomenon known as "volcanic winter": 1816 became known as the "Year Without a Summer" because of the effect on North American and European weather. Crops failed and livestock died in much of the Northern Hemisphere, resulting in the worst famine of the 19th century.

During an excavation in 2004, a team of archaeologists discovered cultural remains buried by the 1815 eruption. They were kept intact beneath the 3m-deep pyroclastic deposits. At the site, dubbed the "Pompeii of the East", the artifacts were preserved in the positions they had occupied in 1815. Upon the eruption, Tambora's height was almost cut in half and formed one of the largest volcanic craters in the world. As one of the majestic destinations in Indonesia, Tambora offers adventurous treks, vast nature view of Indonesia's eastern hemisphere, and an unforgettable experience.
