Krakatoa.

Krakatoa is a 1933 American Pre-Code short documentary film produced by Joe Rock. The story describes how the 1883 eruption of Krakatoa on the island blew half of the large island into the air that produced a tsunami, and an air wave that was felt seven times around the globe. The eruption also emitted tons of dust that dimmed the sun all over the world for many months. It won the Academy Award in 1934 for Best Short Subject (Novelty).
