  abstract = {{P}>{T}he {G}uerrero 2006 {S}low {S}lip {E}vent ({SSE}), {M}exico, one of the world's largest observed {SSE}s, was recorded at 15 continuous {GPS} stations. {T}his event provides the opportunity to analyse in detail the spatial and temporal evolution of slip at depth, and to constrain the characteristics of a large {SSE}. {W}e perform an inversion in two steps. {F}irst, we invert the cumulative {GPS} displacements to retrieve the total slip amplitude. {S}econd, we invert for the initiation time and duration of the slip, using a linearized least-squares inversion procedure and assuming a functional form for the slip function. {O}ur results show that the slip is located on a patch of 300 km x 150 km (parallel and perpendicular to the coast, respectively), and extends from the bottom of the seismogenic zone to the transition zone. {T}his slow slip event has an equivalent moment magnitude of 7.5. {T}he maximum slip over a length scale of 25 km is 15 cm and the mean slip is 5.5 cm. {I}ts lateral extension coincides with the segmentation of the subduction. {O}ur inversion scheme allows us to analyse the spatial variability of the rise time, rupture velocity and slip function. {W}e obtain a continuous image of the spatial and temporal variations of slip on the fault plane. {T}he rupture initiated at a depth of 40 km (transition zone), in the western part of the {G}uerrero gap. {T}he rupture then propagated from the western to the eastern part of the {G}uerrero segment with an average velocity of 0.8 km d-1. {O}ur results show that a slip dislocation pulse, characterized by a symmetric ramp function, can model the 2006 {SSE}. {T}he rise time (local duration of slip) does not show large spatial variations and is equal to about 185 d. {T}he local slip duration is compared to the total duration (11-12 months) of the event, suggesting a large interaction of a large part of the fault during the dynamic process. {W}e find that our inverted slip model is well resolved on the shallow part of the fault and in the central section of the fault.},
