Mount Tambora is an active stratovolcano, also known as a composite volcano, on the island of Sumbawa, Indonesia.

*A stratovolcano, is a tall, conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash .Stratovolcanoes are characterized by a steep profile and periodic, explosive eruptions and quiet eruptions. The lava that flows from stratovolcanoes typically cools and hardens before spreading far due to high viscosity.

How was Mount Tambora formed

It was formed by the active subduction zone beneath it which raised the mountain as high as 4,300m making it one of the tallest peaks in the Indonesian archipelago.

1815 ERUPTIONThe eruption of Mount Tambora in 1815

is noted to be one of the most powerful eruptions in historic times, Tambora caused tsunamis and days of darkness.It also caused the temperature to decrease ,and that year it was called the Year Without Summer.

The volcanic eruption claimed as many as 117,000 lives in Indonesia alone, and subsequently killed hundreds of thousands of people across the Northern Hemisphere.

Is Mount Tambora still active?

Scientific experiments have indicated that Tambora had been dormant for 5,000 years but magma had been building up in the chamber. This build-up had reached its limit in 1815(what was showed just know).

Mount Tambora is still active. 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 very small, non-explosive eruption
