Nestled between the large Indonesian islands of Java and Sumatra is the Krakatau Volcano National Park. In the fourth century, a single marine volcano stood at this site, but in 416 A.D., the caldera of the volcano collapsed. The remnants formed a new caldera around 7 km (4 miles) in diameter, with the peak’s remnants becoming the three islands of Verlaten, Lang, and Krakatau (formerly known as Krakatoa). This volcano remnant was not dormant, however, and in August 1883 the volcano on Krakatau erupted with such violence that the sound was heard as far away as Madagscar and Alice Springs, thousands of kilometers away. Two-thirds of the island was destroyed and roughly 20 cubic kilometers of rock was lofted into the atmosphere. It was one of the largest explosions on Earth in recorded history. The eruption also raised a tsunami 40 meters (130 feet) high which resulted in an estimated 36,000 deaths when it washed ashore as much as 10 kilometers inland from the coast of nearby islan
