Please remember to support my work with donations. I am also trying to get enough donations so I can buy new Raspberry shake seismometers since my current hardware is out of date and is now difficult to maintain. Thanks for the support. 🙂

Katla volcano releases massive amount of CO2 daily

According to new study into CO2 release of Katla volcano the amount released by the volcano is massive. According to the news on Rúv the daily amount released of CO2 is 20 kiloton (1 kiloton = 1000 tons). What is not known today is if this high release of CO2 is constant or if it fluctuates during the year. More reaches is needed into that possible.

I don’t know how much magma is needed for this amount of CO2 release from Katla volcano. What I do know is that it is not little amount of magma inside Katla volcano. Largest documented eruption in Katla volcano had a VEI size of 5. The Eldgjá eruption in 934 was more lava than volcano ash and that was the largest eruption in Katla volcano for a long time. It is not possible to predict an eruption in Katla volcano or any other volcano with good precision.

This makes Katla volcano the 3rd largest CO2 releasing volcano in the world.
