Mt Unzen, Japan: The eruption of Mt. Unzen stands as Japan's most fatal volcanic explosion. The eruption caused the collapse of the volcano's dome, initiating a massive landslide that engulfed the city of Shimabara and extended into the ocean, resulting in a tsunami with a towering height of 57 meters. This devastating event claimed the lives of approximately 15,000 people.
