Short summary
This study examines stress drops sequences in elasto-plastic media using 2D simulations, highlighting the importance of high temporal and spatial resolutions in capturing stress evolution and strain fields. Stress drops reflect fault rupture mechanics and emulate earthquake behavior. The non-Gaussian distribution of stress drop amplitudes resembles "solid turbulence." Elasto-plastic models simulate key earthquake processes and could improve seismic hazard assessment.
