10 Most Devastating Natural Disasters in Indonesia's History

Indonesia is one of the most disaster-prone countries in the world. With 13 percent of the world’s volcanoes located in the Indonesian Archipelago, it has the potential to cause natural disasters such as earthquakes, tsunamis or volcanic eruptions with varying intensities and strengths. 

Located on the three main plates of the world, namely the Australian Plate, Eurasian Plate and Pacific Plate and located in the Ring of Fire and located in the Pacific Ring of Fire region, Indonesia is home to 127 active volcanoes and major earthquake events every year making Indonesia often hit by catastrophic natural disasters and volcanic eruptions.  

Here are 10 of the most devastating natural disasters in Indonesia’s history.

Krakatau eruption on August 26, 1883 was one of the deadliest and most devastating volcanic eruptions in the history of the world with at least 36,417 deaths from eruptions and tsunamis.
Meanwhile, ships sailing as far as South Africa reported tsunami shocks and bodies of victims adrift at sea months after the incident. Merak city and cities along the northern island of Sumatra were hit by tsunamis up to 40 km to the mainland. While the islands around Krakatau almost completely disappeared except for the three islands in the south that still exist to this day.

The most devastating natural disaster in Indonesia’s history was the Tambora Eruption that occurred on Sumbawa Island in 1815. The eruption was heard up to 2,600 km and ash fell for at least 1,300 km. Darkness was visible up to 600km from the top of the mountain for more than two days with pyroclastic flows spreading at least 20km from the summit.
As a result of this eruption of Mount Tambora, all the vegetation on Sumbawa Island died, a large tsunami struck several Indonesian beaches and the height of the eruption smoke could reach the stratoster with an altitude of more than 43 km. Ash particles fall 1 to 2 weeks after an eruption and some ash particles remain in the Earth’s atmosphere for several years at an altitude of 10 – 30 km and the radiance of the twilight sky appears orange or red near the horizon, causing 88,000 people to die and famine and disease after an eruption.

The Eruption of Toba was one of the most devastating natural disasters in Indonesia’s history that occurred at 66,000 – 77,000 years ago in what is now called Lake Toba region, North Sumatra Province. The Toba eruption is also recognized as one of the deadliest volcanic eruptions in the history of the world. The toba disaster hypothesis holds that the most devastating natural disaster in Indonesia’s history resulted in volcanic winters around the world for 6 – 10 years and a cooling period of 1,000 years.
In addition, the Toba Eruption also caused a shrinkage of human evolution and major changes to the topography of the region because its eruptions are estimated to be 100 times larger than the largest eruptions in modern history.
Currently, the Indonesian government continues to make ongoing efforts to reduce the impact of disasters on people and property by preparing for natural disasters including all activities carried out before the detection of signs of disaster in order to facilitate the use of available natural resources. request assistance and and rehabilitation plans in the best possible ways and possible.
