  abstract = {{A} dense {GPS} network deployed in {E}cuador reveals a highly heterogeneous pattern of interseismic coupling confined in the first 35 km depth of the contact between the subducting oceanic {N}azca plate and the {N}orth {A}ndean {S}liver. {I}nterseismic models indicate that the coupling is weak and very shallow (0-15 km) in south {E}cuador and increases northward, with maximum found in the rupture areas of large ({M}w > 7.0) megathrust earthquakes that occurred during the 20th century. {S}ince the great 1906 {M}w = 8.8 {C}olombia-{E}cuador earthquake may have involved the simultaneous rupture of three to six asperities, only one or two asperities were reactivated during the large seismic sequence of 1942 ({M}w = 7.8), 1958 ({M}w = 7.7), 1979 ({M}w = 8.2) and 1998 ({M}w = 7.1). {T}he axis of the {C}arnegie {R}idge, which is entering the subduction zone south of the {E}quator, coincides well with the location of a 50 km wide creeping corridor that may have acted as persistent barrier to large seismic ruptures. {S}outh of this creeping region, a highly locked asperity is found right below {L}a {P}lata {I}sland. {W}hile this asperity may have the potential to generate an {M}w similar to 7.0-7.5 earthquake and a local tsunami, until now it is unknown to have produced any similar events. {T}hat region is characterized by the presence of slow slip events that may contribute significantly to reduce the long-term moment deficit accumulated there and postpone the failure of that asperity. {A}t the actual accumulation rate, a characteristic recurrence time for events such as those in 1942, 1958 and 1979 is 140 +/- 30 yr, 90 +/- 20 yr, 153 +/- 80 yr respectively. {F}or the great 1906 event, we find a recurrence time of at least 575 +/- 100 yr, making the great 1906 earthquake a rare super cycle event.},
