The Toba Supervolcano is located in Sumatra, Indonesia, and is one of the largest volcanic systems on Earth. It erupted approximately 74,000 years ago, creating a massive caldera that is about 100 kilometers wide. This eruption is believed to have had significant effects on the global climate, leading to a volcanic winter. The caldera is now filled with Lake Toba, which is the largest volcanic lake in the world. The area around the supervolcano is rich in biodiversity and is home to various species, making it an important ecological region. Today, it is also a popular tourist destination, attracting visitors with its stunning landscapes.
