The 1883 eruption that circled the globe with sound
In short: Explore the science behind one of history's most violent geological events. This documentary breaks down how a single volcanic explosion in Indonesia produced the loudest sound ever recorded and sent shockwaves around the planet.
The 1883 eruption of Krakatoa, located in the Sunda Strait between Java and Sumatra, was driven by the subduction of the Indo-Australian Plate beneath the Sunda Plate. This tectonic process places the volcano within the Pacific Ring of Fire, a region with the highest concentration of active volcanoes on Earth.
The event produced massive tsunamis and pyroclastic flows that killed more than 36,000 people. Its acoustic power was so immense that it was heard thousands of kilometers away, while atmospheric shockwaves circled the globe multiple times. To provide perspective on this catastrophe, the film evaluates its Volcanic Explosivity Index (VEI) alongside historical occurrences such as Mount Toba's ancient super-eruption and the 1815 Mount Tambora event. The story continues today with ongoing activity in the Sunda Strait and the emergence of Anak Krakatau, or "Child of Krakatoa."
