What type of plate boundary is Mount Tambora on?
TECTONIC SETTING AND GEOLOGY OF TAMBORA VOLCANO. Tambora is a large shield-like alkaline volcano on Sumbawa in the eastern part of the Sunda arc (Fig. 1), associated with the northward subduction of the Indo-Australian plate beneath the Eurasian plate at ∼6–7 cm a−1 (Hamilton, 1979).
What type of volcano is Mt Tambora?
The massive Tambora stratovolcano forms the entire 60-km-wide Sanggar Peninsula on northern Sumbawa Island. The largely trachybasaltic-to-trachyandesitic volcano grew to about 4,000 m elevation before forming a caldera more than 43,000 years ago.
How was Mount Tambora formed?
Sumbawa is flanked both to the north and south by oceanic crust, and Tambora was formed by the active subduction zones beneath it. This raised Mount Tambora as high as 4,300 m (14,000 ft), making it one of the tallest peaks in the Indonesian archipelago, and drained off a large magma chamber inside the mountain.
Is Mount Tambora a subduction zone?
Mount Tambora is located on the island of Sumbawa, Indonesia (Fig. 1). The island is in between tectonic plates, which creates a subduction zone beneath Tambora (Fig. 2).
What is the latitude of Mount Tambora?
8.2479° S, 117.9911° E
What are the characteristics of Mount Tambora?
Its eruptive characteristics included central vent and explosive eruptions, pyroclastic flows, tsunamis and caldera collapse. This eruption had an effect on global climate. Volcanic activity ceased on 15 July 1815.
What is the elevation of Mount Tambora?
Mount Tambora, also called Mount Tamboro, Indonesian Gunung Tambora, volcanic mountain on the northern coast of Sumbawa island, Indonesia, that in April 1815 exploded in the largest volcanic eruption in recorded history. It is now 2,851 metres (9,354 feet) high, having lost much of its top in the 1815 eruption.
What are the crater dimensions of Mount Tambora?
The huge caldera—6 kilometers (3.7 miles) in diameter and 1,100 meters (3,609 feet) deep—formed when Tambora’s estimated 4,000-meter- (13,123-foot) high peak was removed, and the magma chamber below emptied during the April 10 eruption.
What is the plate tectonic setting of the Mount Tambora volcano?
Mount Tambora formed at a convergent plate boundary, where the Indo-Australian Plate subducts under the Eurasian Plate. Tambora is a stratovalcano, with an elevation of 2,850m (9,350ft). When the volcano erupted in 1815, it was given a volcanic explosion index (VEI) of 7.

Is Mount Tambora active or inactive?
Mount Tambora is still active and minor lava domes and flows have been extruded on the caldera floor during the 19th and 20th centuries. The last eruption was recorded in 1967. However, it was a gentle eruption with a VEI of 0, which means it was non-explosive.
