Krakatau (English: Krakatoa) is a volcanic archipelago that is still active and is located in the Sunda Strait between the islands of Java and Sumatra which are included in the nature reserve area. This name was once pinned on one peak of the volcano there (Mount Krakatau) which vanished due to its own eruption on August 26-27, 1883. The eruption was very powerful; hot clouds and the resulting tsunami killed around 36,000 people. Until before December 26, 2004, this tsunami was the most devastating in the Indian Ocean region. The sound of the eruption was heard in Alice Springs, Australia and Rodrigues Island near Africa, 4,653 kilometers. Its explosive power is estimated at 30,000 times the atomic bomb detonated on Hiroshima and Nagasaki at the end of World War II.

The Krakatau eruption caused global climate change. The world was dark for two and a half days due to volcanic dust that covered the atmosphere. The sun shines dim until next year. Scattering dust appears in the skies of Norway to New York.

The Krakatau explosion is actually still inferior compared to the eruptions of Mount Toba and Mount Tambora in Indonesia, Mount Tanpo in New Zealand and Mount Katmai in Alaska. But the mountains erupted far in the time when the human population was still very small. While when Mount Krakatoa erupted, the human population was already quite dense, science and technology had developed, the telegraph had been found, and submarine cables had been installed. Thus it can be said that at that time information technology was growing and developing rapidly.
It was noted that the eruption of Mount Krakatau was the first major disaster in the world after the discovery of the underwater telegraph. Such progress, unfortunately, has not been matched by progress in the field of geology. Geologists at that time were not even able to provide an explanation of the eruption. Mount Krakatau which erupted, the vibration was felt to Europe.
Seeing the area of Mount Krakatau in the Sunda Strait, experts estimate that in ancient times there was a very large mountain in the Sunda Strait which finally erupted devastatingly leaving a caldera (large crater) called Mount Krakatau Purba, which is the mother of Mount Krakatau which erupted at 1883. This mountain is composed of andesitic rocks.
Notes on the Purba Krakatau eruption taken from an Old Javanese text entitled King Parwa Library which is thought to date from 416 AD. Its contents include:
There was a thunderous sound coming from Mount Batuwara. There is also a terrifying shaking of the earth, total darkness, lightning and lightning. Then came the terrible winds and rain, and all the storms darkened the whole world. A large flood came from Mount Batuwara and flowed eastward to Mount Kamula ... When the water sank it, the island of Java separated into two, creating the island of Sumatra
Berend geologist George Escher and a number of other experts argue that the natural events described are from Mount Krakatau Purba, which in the text is called Gunung Batuwara. According to the Parwa King Library book, this ancient Krakatau height reaches 2,000 meters above sea level, and its coastal circle reaches 11 kilometers.
As a result of the great explosion, three quarters of the body of Ancient Krakatoa was destroyed leaving the caldera (large crater) in the Sunda Strait. The sides or edges of the crater are known as Rakata Island, Panjang Island and Sertung Island, in other notes referred to as Rakata Island, Small Rakata Island and Sertung Island. This eruption was allegedly responsible for the occurrence of the dark ages on earth. Bubonic pest disease occurs because the temperature cools. This sampar significantly reduces the population on earth.
This eruption was also considered to have contributed to the end of ancient Persia, the transmutation of the Roman Empire to the Byzantine kingdom, the end of South Arabia civilization, the extinction of the great Mayan city, Tikal and the enigmatic fall of Nazca civilization in South America. Ancient Krakatoa explosion is estimated to last for 10 days with an estimated speed of mass vomit reaching 1 million tons per second. The explosion has formed an atmosphere shield as thick as 20-150 meters, reducing the temperature by 5-10 degrees for 10-20 years.
