Session 1.1 GNGTS 2024 TABLE 2. Magnitude values at each staton calculated by using the frst approach with equaton for the magnitude ‘MLRI35’ and the second approach with equaton for ‘ML_Donegal’, their standard deviatons and the corresponding number of statons used to reach the fnal averaged ML value. CONCLUSIONS Our results indicate that the majority of the micro-seismicity is present with magnitudes lower than 2 (the highest magnitude is 2.8). The recorded seismicity is almost clustered along previously mapped NE-SW trending, steeply dipping faults and confned within the upper crust (focal depth less than 10 km). We also recorded anthropogenic seismicity mostly related to quarries' actvity in the study area. REFERENCES Grannell, J., Arroucau, P., Lebedev, S., Moellhof, M., & Bean, C. J. (2018).
