Exactly 200 years ago, as I am writing this, the most powerful volcanic eruption in recorded history had just started, blowing almost 2,000 meters off the top of a mountain called Tambora on the island of Sumbawa in Indonesia. It was a devastating event for whole world. The eruption caused the “Year without Summer” in the northern hemisphere when it snowed in London and New York in July and crops failed all over Europe, North America and China. There was famine in Switzerland (they must have cut down on the fondue over there). The more indirect effects include the birth of the Frankenstein story and Mormonism, some pretty works of art, real estate bubbles, cholera going global and Arctic exploration.
On April 10, 1815, Tambora woke up, blew up and completely destroyed its immediate surroundings. Whole cultures were wiped out, including the Tambora people and their Tambora language that was the easternmost non-Austronesian (Papuan) language at the time (little known fact, you are welcome!). Alas!
