Víti is a huge explosion crater, about 300 metres in diameter. The crater was formed during a massive volcanic eruption at the start of the famous Mývatn Fires in 1724. The eruption continued more or less non-stop for 5 years and Víti’s bubbling cauldron of mud boiled for more than a century after that.
