About the volcano

Krakatau lies between Java and Sumatra. On 26–27 August 1883 a series of colossal explosions destroyed most of the island; the bang was heard as far away as Rodrigues in the Indian Ocean, and the pressure wave circled the Earth several times. The tsunami killed more than 36,000 people on the coasts of Java and Sumatra, and dust in the atmosphere coloured sunsets around the world. In 1927 a new volcano emerged from the caldera – Anak Krakatau, the “child of Krakatau”. In December 2018 a collapse of its flank triggered a tsunami that killed more than 400 people.

Eruption history

VEI – Volcanic Explosivity Index: 0 = lava outpouring, 4 = like Eyjafjallajökull 2010, 6 = like Pinatubo 1991, 7 = like Tambora 1815. The scale is logarithmic – each step is about 10 times more material.
