[5] Indonesia had the deadliest earthquake and volcanic eruption on the history
You may assume that the eruption of Krakatoa was most destructive, which is not half-wrong. However, according to an article by Becky Little, the deadliest and most destructive volcanic eruption in history was the mount Tambora on Sumbawa island in 1815.
Accordingly, 100.000 people died as a direct impact of the blast, but it led to tens of millions of deaths.
Gillen D’Arcy Wood, the author of Tambora: The Eruption That Changed the World, stated in his book that the eruption led to “three years of climate change,” where the world temperature increased. The weather system changed completely, which led to widespread crop failure and starvation in Asia, the United States, and Europe.
Additionally, in December 2004, a 9.3 magnitude earthquake hit in the Indian Ocean. Nearly all the casualties and damage took place within the province of Aceh, Sumatra. According to the UN and Indonesia’s National Disaster Relief Coordination Agency, it resulted in 250.000 deaths, 37.063 missing, and over 655,000 scattered as refugees.
Other than the physical damage on the province, the aftermath of the tsunami was the breakout of cholera, diphtheria, and other diseases, which further led to the need to create makeshift mass graves.
