Abstract Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress conditions deep within fault zones. Near the Mendocino Triple Junction, a tremor cluster ceased abruptly following each of three Mw 6.0+ earthquakes (2020–2024), including the 2024 Mw 7.0 Mendocino fault earthquake. Moment tensor inversion reveals a high‐angle, right‐lateral strike‐slip mechanism for this tremor cluster. Coulomb stress modeling indicates the tremor cluster is located in a region where Coulomb stress was increased by the mainshock. During the recovery phase of tremor activity, we observed a clear migration trend. Integrating these observations with tomography, we suggest that fluid‐related processes may have contributed to tremor suppression and recovery. Our results provide a broader framework for understanding how large earthquakes modulate slow fault slip beyond stress shadow effects.
