The crust holds the oceans and forms the continents below us, the second and most thickest layer is the mantle, the mantle is a thick layer made up of molten rock, the third layer in the outer core it is the second hottest and the inner core and is the hottest part of the earth.

Volcano disaster 

Mt. Tambura is the deadliest eruption in recent human history, claiming the lives of up to 120,000 people. On 10 April 1815, Tambura erupted sending volcanic ash 40km into the sky. It was the most powerful eruption in 500 years. Upon entering the ocean, the force of the pyroclastic flow caused the creation of a series of towering tsunamis. Thanks to the enormous amount of SO2 emitted, the world experienced a severe temperature drop that led to global crop failures.
