Scientists believe carbon dioxide (CO2) release into the atmosphere from Earth's interior takes place mostly via degassing from active volcanoes. CO2 can also escape along faults away from active volcanic centers. However, such tectonic degassing is poorly constrained, and to date has been largely unmeasured. DCO's Tobias Fischer (University of New Mexico, USA) and colleagues conducted research to effectively study carbon emissions through fault systems in the East African Rift (EAR) in an effort to understand carbon emissions from Earth’s interior and how it affects the atmosphere. Their work is published in Nature Geoscience, and is part of a continued effort to better quantify global emissions of CO2 from Earth’s interior.
