Volcanoes are formed when magma from within earth upper mantle works its way to the surface at the surface it erupts to form lava flows and ash deposits over time as the volcano continues to erupt it will get bigger and bigger.
Where
Tambora Indonesia the largest recorded volcanic eruption in history Tambora caused enough starvation and disease to kill approximately 80,000 people.
When did it last erupt
Mount Tambora is still active and minor lava domes and flows have been recorded during the 19th and 20th centuries. The last eruption was recorded in 1967
Damage
A shattering blast blew the mountain apart on the evening of April 10. The blast pyroclastic flows, and tsunamis that followed killed at least 10,000 islanders and destroyed the homes of 35,000 more and the economic impact of the eruption is estimated at 1 billion dollars.
Stories/myths
The debris also caused a moderate-sized tsunami. In all, so much rock and ash were thrown out of Tambora that the height of the volcano was reduced from 14,000 to 9,000 feet. The worst explosions were heard hundreds of miles away. The eruptions of Tambora also affected the climate worldwide. The steam off the volcano formed 6 months before the eruption the effect of the volcano can be felt 300 miles away the people who lived in Indonesia in 1815 had to survive a year without summer because of the ash from volcano covering the sky and not moving.
