The eruption of Krakatau, 1883
One of the major disasters in 19th century around the world was the eruption of the volcano Krakatau in western Pacific Ocean, Indonesia.
The volcano erupted in August and was a major disaster by any measure. It killed thousand people on the other islands near him. The volcanic dust thrown into the atmosphere affected the weather around the world, and people as far away as Britain and the United States began to see bizarre red sunsets caused by particles in the atmosphere.
