Session 1.1 GNGTS 2024 stress evoluton at the crack tp. The inferred spatal dimension of the cohesive zone in our models is nearly ~0.3-0.4m, with a maximum slip of ~0.6 cm. Finally, from the generated synthetc waveforms, we examine the diferences in the content of high-frequency radiaton between self- arrestng and run-away earthquakes, also providing an estmaton of the source parameters obtained through the spectral inversion. This estmaton is then compared with the forward models. Our results suggest that meso-scale processes near the crack-tp during the nucleaton and acceleraton of the rupture strongly afect dynamics of micro-earthquakes. Fig. 1 Snapshot of the slip rate evoluton during the rupture propagaton of a microearthquakes (M w = 0.71) in the context of fuid induced seismicity; for the model with D c = 0.6mm.
