Mount Agung erupted in 1963, killing more than 1,000 people on Bali.
Mount Agung is Bali's highest mountain and an active stratovolcano in Indonesia. Its major 1963 eruption began in February and continued for months. Explosive eruptions, ashfall, lava flows, and pyroclastic flows affected large areas, while lahars moved down valleys during heavy rain.
The disaster killed more than 1,000 people and destroyed homes, farmland, and religious sites. The eruption also affected Bali's climate locally and produced extensive ash deposits. Mount Agung later became active again in 2017, prompting evacuations and airport closures.
Mount Agung is sometimes confused with Mount Batur, another famous Bali volcano. Batur occupies an older caldera and is a major tourist destination, whereas Agung is the island's highest summit and the source of the catastrophic 1963 eruption.
