On August 27, 1883, one of the most catastrophic eruptions in human history was recorded. Both the explosion and the amount of materials thrown in the air have exceeded the values at that time.
When Krakatau erupted for the first time, the ash was thrown at an altitude of 27 km in the air. The next day, another three explosions occurred. The last explosion destroyed the northern island of Rakata and the ash reached an altitude of 37 km. It is believed that the sound of the explosion was heard from a distance 4,600 km. By the end of the explosion, the island was completely destroyed the northern part of the island.
The four explosions had the energy of 200 megatons of TNT. As a term of comparison, the bomb at Hiroshima had 20 kilotons. The volcanic ash column reached the 80 km altitude, darkening the sky at 10 AM until the next day. The ash column was seen from Singapore (680 km from the island).
Before the eruption, the island had a width of 5 km and a length of 9 km. After the eruption, approximately 23 square km sank, which is more.
The volcano holds the record in all the effects of an eruption. When the sky became clearer, it was observed that most of the Krakatau volcane had disappeard. Shorty, a new island emerged from the water, which was named Anak Krakatau (Krakatau’s child). The new volcano has an altitude of approximately 300 meters.
