What is it about?
On 24 August 2013 a sudden gas eruption from the ground occurred in the Tiber river delta, nearby Rome’s international airport of Fiumicino. We assessed that this gas, analogous to other minor vents in the area, is dominantly composed of deep, partially mantle-derived CO2, as in the geothermal gas of the surrounding Roman Comagmatic Province. Increased amounts of thermogenic CH4 are likely sourced from Meso-Cenozoic petroleum systems, overlying the deep magmatic fluids.

Why is it important?
The presence of high CO2 and CH4 degassing in the Rome sub-urban area
Perspectives
Pressurized gas may temporarily be stored below these covers or within shallower sandy, permeable layers of the Fiumicino area. The eruption of the 24 August 2013, regardless the triggering cause—natural or man-made, reveals the potential hazard of gas-charged sediments in the delta, even at distances far from the volcanic edifice of Alban Hills
