Katla is an active volcano in southern Iceland with a history of at least twenty major eruptions since 2920 BCE. Its last major eruption occurred in 1918, creating one of the largest glacial floods recorded on Earth. Katla is known to emit copious amounts of carbon dioxide, accounting for up to 4% of global volcanic carbon dioxide emissions. It is considered dangerous due to its past eruptions and current volcanic activity, but at the same time is awe-inspiring due to its mysterious and beautiful form amidst the glaciers and landscape of Iceland.
