The Toba Volcano is a supervolcano located on the island of Sumatra in Indonesia. It is known for its massive eruption approximately 74,000 years ago, which is one of the largest volcanic events in Earth's history. This eruption created the Lake Toba, a large crater lake that is about 100 kilometers long and 30 kilometers wide. The Toba eruption had significant global effects, including a volcanic winter that may have led to a dramatic reduction in the human population. Today, the Toba region is a popular tourist destination, attracting visitors with its stunning landscapes and rich cultural heritage.
