Mount Tambora it’s located in the island of Sumbawa, Indonesia. Tambora’s 1815 outburst was the largest volcanic eruption and the most deadly in recorded history.
After a large magma chamber inside the mountain filled over the course of several decades, volcanic activity reached a historic climax in the super-colossal eruption of April 1815. 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, the explosion was heard on Sumatra island (more than 2,000 km (1,200 mi) away).
The death toll was at least 71,000 people, of whom 11,000–12,000 were killed directly by the eruption.
Experts are now saying that Mount Tambora is ready to erupt again. A steady stream of earthquakes are shaking the island, from less than five a month in April to more than 200 now. Columns of ash are already venting as high as 4,600 feet.
The authorities have already established a 2-mile danger perimeter and its inhabitants are fleeing under government orders. But most of the people know the story from 1815 and don’t need any orders to start running. In fact, people outside of the danger zone are also fleeing out of pure fear.
Mount Tambora (or Tamboro) is an active stratovolcano, also known as a composite volcano, on the island of Sumbawa, 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), making it formerly one of the tallest peaks in the Indonesian archipelago.
During an excavation in 2004, a team of archaeologists discovered cultural remains buried by the 1815 eruption. They were kept intact beneath the 3 m (9.8 ft) deep pyroclastic deposits. At the site, dubbed the Pompeii of the East, the artifacts were preserved in the positions they had occupied in 1815.
