9. The 1815 Eruption of Mount Tambora

The eruption of Mount Tambora in Indonesia in 1815 is considered the most powerful volcanic eruption in recorded history. It resulted in the deaths of around 71,000 people and triggered what became known as the “Year Without a Summer” in 1816.
The eruption released a massive amount of ash into the atmosphere, causing global temperature drops, crop failures, and food shortages. The long-lasting climate effects contributed to widespread famine and further loss of life across the world.
