Slow slip source characterized by lithological and geometric heterogeneity
Slow slip events (SSEs) accommodate a significant proportion of tectonic plate motion at
subduction zones, yet little is known about the faults that actually host them. The shallow …

Subducting volcaniclastic-rich upper crust supplies fluids for shallow megathrust and slow slip
Recurring slow slip along near-trench megathrust faults occurs at many subduction zones,
but for unknown reasons, this process is not universal. Fluid overpressures are implicated in …

Overpressured underthrust sediment in the Nankai Trough forearc inferred from transdimensional inversion of high‐frequency teleseismic waveforms
Active‐source seismic surveys have resolved the fine‐scale P‐wave velocity (Vp) of the
subsurface structure in subduction forearcs. In contrast, the S‐wave velocity (Vs) structure is …

Continent‐continent collision between the south and north China plates revealed by seismic refraction and reflection at the southern segment of the Tanlu fault zone
Abstract The Tanlu Fault Zone (TFZ) is considered as a suture of the intra‐continental
collision between the South and North China plates, and it has attracted considerable …
