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 ...
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 ...
Little Ice Age volcanism refers to the massive volcanic activities during the Little Ice Age. Scientists suggested a hypothesis that volcanism was the major driving force of the global cooling among the other natural factors, i.e. the sunspot activities by orbital forcing and greenhouse gas. The Past Global Change (PAGES), a registered paleo ...
Before the eruption, Mount Samalas may have been as tall as 4,200 ± 100 metres (13,780 ± 330 ft), based on reconstructions that extrapolate upwards from the surviving lower slopes, [12] and thus taller than Mount Kinabalu which is presently the highest mountain in tropical Asia; [13] Samalas's current height is less than that of the ...
Paraná and Etendeka traps, Brazil, Namibia and Angola form 128 to 138 million years ago. 132 million years ago, a possible supervolcanic eruption occurred, ejecting 8,600 cubic kilometers (2,063 cu mi). [90] Formation of the Karoo-Ferrar flood basalts begins 183 million years ago.
The temperature changes were possibly greater than the effects of the 1815 eruption of Mount Tambora. [72] Mazama's climactic eruption produced stratospheric mass loadings of 97,000,000 to 247,000,000 short tons (88 to 224 Mt) of sulfuric acid, with an estimated minimum sulfate degassing of 102,400,000 short tons (92.9 Mt) during its eruption.

Big bombs can measure more than 1.2 meters (4 ft) across and weigh several tons. ... The 1815 eruption of Mount Tambora created global climate anomalies that became ...
