Filling its magma chambers and emitting enormous quantities of CO2 every day.___________________
Katla, hidden beneath the ice cap of Mýrdalsjökull glacier, has historically erupted violently once every 40-80 years. In-as-much as it’s last such eruption took place one hundred years ago, in 1918, Katla’s next eruption is long overdue.
An eruption in Katla would dwarf the 2010 Eyjafjallajökull eruption, scientists have warned.
A new study by Icelandic and British geologists showed that Katla is emitting enormous quantities of CO2 – at least 20 kilotons of C02 every day. Only two volcanoes worldwide are known to emit more CO2, Evgenia Ilyinskaya a volcanologist with the University of Leeds told the Icelandic National Broadcasting Service RÚV.
These enormous CO2 emissions confirm significant activity in the volcano, Evgenia told RÚV: “There must also be a magma build up to release this quantity of gas.”
“It is well known from other volcanoes,” said Evgenia, “that CO2 emissions increase weeks or years ahead of eruptions. This is a clear sign we need to keep a close eye on Katla…. there is something going on.”
