Measurement of interseismic strain along subduction zones reveals the location both locked asperities, which might rupture during megathrust earthquakes, and creeping zones, tend to arrest such seismic ruptures. The heterogeneous pattern coupling presumably relates spatial variations frictional properties interface may also show up in fore-arc morphology. To investigate this hypothesis, we compiled information on extent earthquake ruptures for last 500 years uplift rates derived from dated...
The Sainte‐Victoire System (SVS) is a key area to understand how the shortening accommodated in outer foreland of Pyrenean‐Provence orogen between Late Cretaceous and Eocene. Structural data, growth strata fault slip analysis, four balanced cross sections are used decipher along‐strike geometry, deformational characteristics kinematics SVS. SVS divided into two structural domains separated by regional relay zone: eastern domain governed N‐vergent thin‐skinned tectonic style above Triassic...

We have estimated recent river incision rates using the in situ-produced 36Cl cosmogenic nuclide concentrations. The target site consists of a ~25 m high vertical profile along polished cliff located Jurassic limestones Vésubie catchment area, southern French Alps. exposure ages sampled surface range from 3 to 14 ka, i.e., after Last Glacial Maximum. Our data suggest as first approximation linear age/height relationship and lead mean rate 2.2 mm a−1 over last ka. More precisely, are...
Abstract The link between plate tectonics and the evolution of active margins is still an ongoing task to challenge since acceptance tectonic paradigm. This paper aims at deciphering structural architecture uplift history North Peruvian forearc system better understand mechanics that govern Late Cretaceous‐Cenozoic building this margin. In study, we report surface geology data, interpretation seismic reflection profiles, apatite fission track construction two offshore‐onshore crustal‐scale...
The offshore Tumbes-Guayaquil forearc basin in the accretionary prism of Northern Peru-Southern Ecuador shows evidence gravity-driven large-scale deformation systems active during Late Neogene-Quaternary period. Subsurface data and construction eight structural cross-sections show that ∼8 km-thick Oligocene-Quaternary sedimentary infill is detached seaward completely decoupled from underlying inner systems. Corvina décollement Tumbes Posorja Guayaquil constitute two thin-skinned gravity...
The Colombia–Ecuador subduction zone is an exceptional natural laboratory to study the seismic cycle associated with large and great earthquakes. Since 1906 Mw = 8.6 earthquake, four > 7.5 megathrust earthquakes occurred within rupture area, releasing altogether a cumulative moment of ∼35% moment. We take advantage newly released catalogs global positioning system (GPS) data at scale balance deficit that building up on interface during interseismic period aseismic moments by transient...
Abstract Tephra layers preserved in marine sediments are strong tools to study the frequency, magnitude and source of past major explosive eruptions. Thirty‐seven volcanoes from Ecuadorian Colombian arc, northern Andes, experienced at least one eruption during Holocene. The volcanic hazard is therefore particularly high for populated areas Andes particular cases coastal region, it crucial document such events improve assessment. age distribution deposits Holocene eruptions have been studied...
