English: This detailed astronaut photograph depicts the summit caldera of the volcano. The huge caldera—6 kilometers in diameter and 1,100 meters deep—formed when Tambora’s estimated 4,000-meter-high peak was removed, and the magma chamber below emptied during the 1815 eruption.
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.
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.
Mount Merapi, Semeru and Kelud are the most active volcanoes in Java. Mount Semeru has been continuously erupting since 1967. [15] Mount Merapi has been named as one of the Decade Volcanoes since 1995. [16] Ijen has a unique colourful caldera lake which is an extremely acidic natural reservoir (pH<0.3). [17]
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.
It’s believed about 15,000 people died. In the 1990s, the volcano began grumbling out of its slumber again. Wikimedia Commons. 1815: Mount Tambora, Indonesia.
The Sangeang Api (island of Sangeang) and Satonda are eruption centers associated to the Tambora volcano [7] — and therefore to the phenomenal 10–15 April 1815 eruption of Mount Tambora which ejected 50km 3 of rock (150 km 3 of pumice and pyroclastics) and affected a large part of the Earth. [b]
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 ]
