WebbSlow slip events are distributed globally and, in general, occur at nearly all plate boundaries that generate large earthquakes and have adequate instrumentation to detect them. These criteria are most commonly met at subduction zones, so it is not surprising that the majority of SSEs locate in this tectonic setting. diastolic of 119

Scientific Reports (2024) Webb1 feb. 2024 · These results suggest cycles of slow slip episodes, dilatancy and healing that produce rapid changes in permeability and fluid pressure. To achieve high fluid pressure, pathways for fluid transport along the megathrust or into the overlying mantle wedge or forearc crust may be intermittent [ 41 ].

In the case of Cascadia (Fig. 4a), the slip model was derived from the inversion of geodetic time series33. We selected the time history of the slip on the northern segment of the Cascadia subduction zone, where the signal-to-noise ratio is best and nucleation occurs most frequently (at latitude ~48° N (ref. 33)).
