Introduction
Lake Toba, located in the northern part of Sumatra, Indonesia, is the largest volcanic lake in the world. The diamond-shaped lake is 100 kilometers long and 30 kilometers wide, with a maximum depth of 505 meters and a surface altitude of 905 meters. The island of Samosir in the lake is a popular tourist destination where visitors can rent boats or bikes to explore the lake. However, Lake Toba is not only a beautiful scenery, but also leaves an amazing historical mark. 75,000 years ago, a super volcanic eruption occurred here, which is known as the largest eruption on Earth in the past 250,000 years, with energy release equivalent to one billion tons of high explosive. According to scientists' estimates, this eruption caused climate change and a sharp decrease in the world's population, triggering an ice age. Stanley Ambrose of the University of Illinois proposed the "Toba Catastrophe Theory," which suggests that modern humans are the descendants of survivors of the massive disaster. Although this theory needs more supporting evidence, it has indeed left a valuable historical mark for us to understand human history and civilization development.
