The Colombia–Ecuador subduction zone is an exceptional natural laboratory to study the seismic cycle associated with large and great subduction earthquakes. Since the great 1906 Mw = 8.6 Colombia–Ecuador earthquake, four large Mw > 7.5 megathrust earthquakes occurred within the 1906 rupture area, releasing altogether a cumulative seismic moment...
Forearc systems develop largely offshore above subduction zones between the trenchand the volcanic arc. The associated forearc basins are generally parallel to the trenchand involve vertical movements (subsidence vs. uplift), influencing the dynamics of thewedge. The objectof the study is the Guayaquil-Tumbes forearc basin belonging to...

The link between plate tectonics and the evolution of active margins is still an ongoing task to challenge since the acceptance of plate tectonic paradigm. This paper aims at deciphering the structural architecture and uplift history of the North Peruvian forearc system to better understand the evolution and the mechanics that govern the Late...

Measurement of interseismic strain along subduction zones reveals the location of both locked asperities, which might rupture during megathrust earthquakes, and creeping zones, which tend to arrest such seismic ruptures. The heterogeneous pattern of interseismic coupling relates to spatial variations of frictional properties along the...
Pleistocene uplift of the Chilean coast is recorded by the formation of wave-cut platforms resulting from marine erosion during sea-level highstands. In the Altos de Talinay area (~ 31°S), we have identified a sequence of 5 wave-cut platforms. Using in situ produced 10Be exposure ages we show that these platforms were formed during interglacial...
Extensional faults are often observed along subduction zones as a response of a margincollapse. However, their role remain underestimated within the structural evolution offorearc systems. In southern Ecuador, the oblique subduction of the Nazca Platebeneath South America led to the formation of the Cretaceous-Miocene NW-SEChongón-Colonche...
