Tsunamis are also generated by volcanic eruptions. When volcanic eruptions cause disturbances, then a large amount of water gets displaced from a water source. This displaced water in the form of waves recognized as the tsunami. An example of a tsunami that was caused by the volcanic eruption was the tsunami of 26 August 1883. This was the result of the explosion of the volcano of Krakatau in Indonesia. This was the most destructive and largest tsunami. The tsunami was 135 feet high and killed 36,417 people.
