Q. Which volcanic eruption in 1883 led to devastating tsunamis in Indonesia?
Answer: Mount Krakatoa
Notes: The 1883 eruption of Mount Krakatoa was one of the most violent volcanic events in recorded history. It caused tsunamis that reached heights of 135 feet, obliterating coastal towns on Java and Sumatra, and resulting in over 36,000 deaths. The eruption was so powerful that it was heard over 3,000 miles away, and it significantly affected global climate, leading to the "year without a summer" in 1884.
