Session 1.1 GNGTS 2024 Fig. 1 - Universal propertes of seismicity. Crustal stress gradients and inherited structures determine the scaling propertes of seismicity, hence, the spatal organizaton of faults and fractures and its scaling propertes. Higher fractal dimension of fractures and hypocenters produces strongly clustered seismicity in space with steeper Gutenberg- Richter law and lower corner magnitudes; hence, lower maximum magnitude and vice versa. Moreover, more developed fracturing with thicker damage zones and complex seismogenic sources promote stress accumulaton because of higher internal fricton within the boundary interface and, also, larger stress drops (magnitude fxed) during seismic events. At last, the interacton of fault planes with diferent spatal orientaton is more likely in complex fault systems, which decreases the double-couple component of moment tensors of earthquakes.
