Katla, a giant volcano hidden beneath the ice cap of Mýrdalsjökull glacier, is busy filling its magma chambers. An eruption in Katla would dwarf the 2010 Eyjafjallajökull eruption. The volcano is long “overdue” for an eruption, as it has historically erupted once every 40-80 years. The last known eruption in Katla was in 1918.

A group of Icelandic and British geologists have recently finished a research mission studying gas emissions from the volcano. The studies showed that Katla is emitting enormous quantities of CO2. The volcano releases at least 20 kilotons of C02 every day. Only two volcanoes worldwide are known to emit more CO2. READ MORE
