Mount Tambora, or Tomboro, is an active stratovolcano in West Nusa Tenggara, Indonesia. Located on Sumbawa in the Lesser Sunda Islands, it was formed by the active subduction zones beneath it. Before 1815, its elevation reached more than 4,300 metres (14,100 feet) high, making it one of the tallest peaks in the Indonesian archipelago.
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. This volcanic explosivity index (VEI) 7 eruption ejected 37–45 km 3 (8.9–10.8 cubic miles) of dense-rock equivalent (DRE) material into ...
Caused a volcanic winter that dropped temperatures by 0.4–0.7°C (or 0.7–1°F) worldwide. 1816 is known as the Year Without a Summer because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.7–1 °F). [1] Summer temperatures in Europe were the coldest of any on record between 1766 and ...
The 1815 eruption of Mount Tambora on Sumbawa and the 1257 eruption of Mount Samalas on Lombok were among the largest in the last two millennia, ranking 7 on the VEI scale. [14] The Sunda Arc subduction zone was also the site of one of the largest known eruptions of the Cenozoic , the VEI 8 Toba supereruption on Sumatra , which expelled 2,800 ...
The Toba eruption (sometimes called the Toba supereruption or the Youngest Toba eruption) was a supervolcanic eruption that occurred about 74,000 years ago during the Late Pleistocene [2] at the site of present-day Lake Toba in Sumatra, Indonesia. It was the last in a series of at least four caldera -forming eruptions at this location, with the ...

Seven active volcanoes are visible: 5 in East Java, Agung in Bali and Rinjani in Lombok. The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the Eurasian Plate and the Indo ...
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.
Mount Emmons, Mount Hague, and Double Crater are post-caldera cones. [6] The topography of the Basin and Range Province is a result of crustal extension within this part of the North American Plate (rifting of the North American craton or Laurentia from Western North America; e.g. Gulf of California, Rio Grande rift, Oregon-Idaho graben).
