Correction to: E. Shnyukov, V. Yanko-Hombach, Mud Volcanoes of the Black Sea Region and their Environmental Significance, https://doi.org/10.1007/978-3-030-40316-4

The original version of the book was inadvertently published with incorrect figures (Fig. 3.6 and Fig. 6.27) and caption (Fig. 4.4). These have been corrected now.
