(1,666 ft.) at its deepest point, in the middle of the northern part of the Indonesian island of Sumatra with a surface elevation of about 900 m (3,000 feet), stretching from ২.৮৮° উত্তর ৯৮.৫২° পূর্ব / 2.88; 98.52 to ২.৩৫° উত্তর ৯৯.১° পূর্ব / 2.35; 99.1. It is the largest volcanic lake in the world. In addition, it is the site of the 75,000-year-old supervolcanic eruption, the largest in the last 25 million years; where it staged a massive climate-changing event that scientists believe might have wiped out much of humanity. The massive eruption is believed to have a VEI intensity of 8.
