Maps produced from the results of the survey performed by the international scientific team and local institutes: (a) CO2 flux from fractures and soils, (b) CO2 content in the air close to the soil, (c) temperature within the fractures and in the soil (20 cm-depth). (d) Interferogram showing the ground deformation related to the dyke propagation. The large-scale deformation pattern (Supplementary Fig. S4) displays two lobes with opposite axis34. The propagation path is therefore interpreted to be nearly North–South, similar to the network of fractures.
