Toba Lake

Toba Lake, located in Indonesia on the island of Sumatra, is one of the world's largest volcanic lakes and caldera systems. It was formed by a massive volcanic eruption around 74,000 years ago, which created a deep, crater-like basin filled with water. The lake measures about 100 kilometers in length and over 500 meters deep. It is renowned for its stunning scenery, rich biodiversity, and significance for climate history, as the eruption is thought to have caused a global volcanic winter. Today, Toba Lake is a vital ecological and cultural site, supporting local communities and tourism.
