A  lithograph of 1883 eruption of Krakatoa.

One of the most powerful volcanic eruptions in recorded history occurred on Krakatoa (also called Krakatau), a small, uninhabited volcanic island east of Sumatra and west of Java, on August 27,
1883. Heard 3,000 miles away, the explosions threw five cubic
miles of earth 50 miles into the air, created 120-foot tsunamis
and killed 36,000 people.
