1816 – The Year Without a Summer: How the Eruption of Mount Tambora Shook the World"

In April 1815, on the island of Sumbawa (Indonesia), the most powerful volcanic eruption in recorded history took place — Mount Tambora.
The explosion was heard over 2,000 km away, and it hurled vast amounts of ash and sulfur into the upper atmosphere.

The result? 1816 became known as “The Year Without a Summer.”
Global temperatures dropped, snow fell in June, crops failed across Europe and North America, and famine spread worldwide.

Fun fact: Trapped indoors in stormy Geneva that summer, a group of writers held a ghost story contest. Mary Shelley, inspired by the eerie mood, began writing what would become Frankenstein.
