## 5 Conclusions  
To summarize, the presented results highlight the complex seismicity patterns that were observed during a two-year period in the Western Gulf of Corinth. The high resolution earthquake catalogue enabled the recognition of the activated structures at depth and their possible relation to mapped faults on the surface. The detailed spatiotemporal evolution of seismicity revealed interactions between neighboring structures via a migrating active patch, likely associated with increased pore-pressure. Measurements of shear-wave parameters were performed on a larger scale than ever before in the WGoC through an automated procedure, validating previous results from manual analysis and providing new information at different sites or study periods. The seismic monitoring of the WGoC over the past 20 years has been providing valuable information on the manners with which seismicity is evolved, driven by fluids that propagate through the microfracture network, enabling aseismic creep, triggering swarms and mainshock-aftershock sequences on their way. The high deformation rate in this part of Central Greece ensures that such patterns will continue to emerge and may eventually lead to significant and destructive events. The understanding of the dynamics of seismicity may therefore play an important role for the assessment of seismic hazard in the area. **Supplementary Materials:** The following are available online at [[https://www.mdpi.com/article/10.3390/app11146573/s1](https://www.mdpi.com/article/10.3390/app11146573/s1)]([https://www.mdpi.com/article/10.3390/app11146573/s1](https://www.mdpi.com/article/10.3390/app11146573/s1)), Section S1: Location/Relocation statistics for Catalogue 1, Section S2: Seismic moment measurements, Section S3: Automatic picking for Catalogue 2, Section S4: Additional tables and figures, File S1: 3D Interactive Matlab Figure, Dataset D1: Catalogue of seismicity, Dataset D2: Anisotropy measurements, Table S1: Absolute location error and other statistics per spatial group (see Figure 2) for the seismicity of 2013-2014 (Catalogue 1) in the Western Gulf of Corinth (WGoC).
