According to the latest study, scientists have discovered that Machu Picchu, one of the seven wonders of the world, is much older than earlier thought. Situated in southern Peru, Machu Picchu is a 15th-century Inca site. Machu Picchu was a country estate of Inca Emperor Pachacuti located on the eastern face of the Andes Mountains.
Around 74,000 years ago, a “supereruption” on the island of Sumatra, Indonesia, blasted out an estimated 5,000 cubic kilometres of magma. This was the Toba eruption, the largest volcanic eruption of the past 2 million years. To put 5,000 cubic kilometres of magma in perspective, this is more than a hundred times as large as the 1883 eruption of Krakatoa, and included enough ash to blanket the entire United Kingdom about 1 millimetre deep.
