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 the 1815 eruption , its elevation reached more than 4,300 metres (14,100 feet) high, making it one of the tallest peaks in the Indonesian ...
The main cause of the Year Without a Summer is generally held to be a volcanic winter created by the April 1815 eruption of Mount Tambora on Sumbawa. [ 7 ] [ 8 ] [ 9 ] The eruption had a volcanic explosivity index (VEI) ranking of 7, and ejected at least 37 km 3 (8.9 cu mi) of dense-rock equivalent material into the atmosphere. [ 10 ]

This cooling directly or indirectly caused 90,000 deaths. The eruption of Mount Tambora was the largest cause of this climate anomaly. [22] While there were other eruptions in 1815, Tambora is classified as a VEI-7 eruption with a column 45 km (148,000 ft) tall, eclipsing all others by at least one order of magnitude.
The peak after 1815 was caused by the Mount Tambora eruption. The 1808 mystery eruption is one or potentially multiple unidentified volcanic eruptions that resulted in a significant rise in stratospheric sulfur aerosols, leading to a period of global cooling analogous to the Year Without a Summer in 1816. [2] [3] [4]
The only unambiguous VEI-7 eruption to have been directly observed in recorded history was Mount Tambora in 1815 and caused the Year Without a Summer in 1816. The Minoan eruption of Thera in the middle of the second millennium BC may have been VEI-7, but may have been just shy of the 100 cubic kilometers required.

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).
