Explanation

The Toba supervolcano in Indonesia (Sumatra island) contains the world's greatest volcanic crater, approximately 100 km by 30 km in size. It was formed by a massive super-eruption around 74,000 years ago, one of the largest volcanic events in Earth's history. Lake Toba now fills much of this caldera.
