  abstract = {{S}low slip events ({SSE}s) are transient slip episodes taking place along the plate interface of subduction zones. {T}hey usually occur synchronously to tectonic tremors and/or seismic swarms, but the relationship between slip and seismicity remains unclear. {H}ere, we study a well-instrumented seismic swarm-{SSE} sequence near a highly coupled segment along the {E}cuadorian subduction zone. {GPS} data reveal that a one-week long {SSE} developed along the subduction interface at shallow depth (5-15 km) with an equivalent moment magnitude ({M}w) of 6.3. {D}uring that period, a local temporary seismic network recorded >700 earthquakes with magnitudes ranging between 1.0 and 4.6. {T}he distribution of seismicity illuminates a steep intraslab fault downdip of an oceanic relief, striking almost parallel to the trench. {T}his seismicity migrates along strike of this active structure at a velocity of 10-15 km/day. {T}his velocity is commonly observed in the case of slow slip propagation. {O}ur observation suggests that the interplate {SSE} might have triggered a slow slip along the the intraslab active structure, which in turn drove the intraslab seismicity. {I}n addition, at the northern part of the intraslab faults, a cluster of seismicity shows a radial expansion compatible with a fluid diffusion process. {O}verall, our study highlights the dynamical interaction between an interplate slow slip and an intraslab seismic swarm with the interplay of an intraslab aseismic slip propagation and fluid diffusion, both controlling the migration of seismicity.},
