On April 16 2016, a magnitude 7.8 earthquake occurred along the Nazca-South America plate interface near the city of Pedernales in Ecuador. GPS measurements in the years prior to the earthquake had indeed shown a partial and spatially heterogeneous pattern of interseismic coupling in central-northern Ecuador (Nocquet et al., 2014, Chlieh et...

The North Andean Sliver (hereinafter NAS) lies at the northwestern end of the South American plate (hereinafter SOAM). This extensive area exhibits a complex deformation process controlled by the interactions of Nazca, Caribbean, South America plates, and Panama block, producing crustal seismicity, arc-continental collision, and subduction...

Many studies of postseismic deformation following large earthquakes focus on time scales ranging from weeks to years following the main earthquake. By contrast, fewer studies have investigated the spatio-temporal distribution of postseismic deformation in the hours to days following the mainshock. Focusing on this early postseismic period is...

In the Northern Andes, partitioning of oblique subduction of the Nazca plate beneath the South American continent induces a northeastward motion of the North Andean Sliver. The strain resulting from this motion is absorbed by crustal faults, which have produced magnitude 7 + earthquakes historically in the Andean Cordillera of Ecuador and...
