Where is the world's largest active caldera located?
Quick Answer
The largest active caldera is Toba, on the Indonesian island of Sumatra. It is a vast volcanic depression formed by a supereruption about 74,000 years ago.
The Full Story
The Toba caldera lies in North Sumatra, Indonesia. It formed after one of the largest explosive eruptions known on Earth, about 74,000 years ago, which left behind a huge caldera now partly filled by Lake Toba. The eruption ejected enormous volumes of ash and pumice and had major environmental effects far beyond Indonesia. Today, the site remains volcanically active and closely studied by geologists.
