GEOLOGY

Detailed explanation-1: -The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or “super-colossal") on the Volcanic Explosivity Index, the second-highest rating in the index. The volcano, which is still active, is one of the tallest peaks in the Indonesian archipelago.

Detailed explanation-2: -Most shield volcano eruptions are nonexplosive (effusive), usually 0-1 on the Volcanic Explosivity Index (VEI), typically in the Hawaiian eruptive style. These eruptions produce fluid lava flows and may produce fire-fountains. High rates of eruptions help produce lava flows that travel fast and can cover large areas.

Detailed explanation-3: -Stratovolcanoes are more likely to produce explosive eruptions due to gas building up in the viscous magma.

Detailed explanation-4: -The six eruption types are in order from least explosive to the most explosive; Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian.
