Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

Geophysical Research Letters
Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador.

Interseismic Coupling and Quaternary Coastal Tectonics along the Andean Megathrust

, 2018
International audienceThe Andean margin is one of the most active subduction zone worldwide (e.g., the1960 Mw 9.5 Chile or the Mw 8.8 1906 Ecuador earthquakes).

Geodetic plate coupling and seismic potential on the main Himalayan thrust in Nepal

Earth, Planets and Space
We model interseismic plate coupling distribution on the Main Himalayan Thrust (MHT) in Nepal through the inversion of secular GNSS velocity data. To complement previously published data, we compile velocity data from ten additional continuous stations ...

Modeling the 2023 Türkiye Earthquakes and Strain Accumulation Along the East Anatolian Fault Zone: Insights from InSAR, GNSS, and Small-Magnitude Seismicity, with Implications for the Seismic Potential at Rupture Terminations

Remote Sensing
The 6 February 2023 MW 7.8 and MW 7.6 earthquakes in southeastern Türkiye ruptured more than 400 km of the East Anatolian Fault Zone (EAFZ), producing one of the most destructive seismic sequences in recent history.

Seismotectonic Setting of the Andes along the Nazca Ridge Subduction Transect: New Insights from Thermal and Finite Element Modelling

Geosciences
The structural evolution of Andean-type orogens is strongly influenced by the geometry of the subducting slab. This study focuses on the flat-slab subduction of the Nazca Ridge and its effects on the South American Plate.

Bayesian inference of interseismic coupling along the East Anatolian Fault using geodetic data

Historically, the East Anatolian Fault Zone (EAFZ) has regularly produced MW ~ 7 earthquakes, but has also occasionally ruptured in MW ~ 8 events. After a century without any significant earthquake, the MW 6.8 Elazığ (24 Jan.

Estimation of the fault geometry of the Median Tectonic Line (MTL) in Eastern Shikoku, Southwestern Japan, via GNSS and InSAR time series analysis

Earth, Planets and Space
The Median Tectonic Line (MTL) is one of the largest active fault systems in Japan. Whether the active MTL fault is north-dipping or near-vertical is still under debate.

A 3D finite-element mesh for modeling large-scale surface deformation induced by subduction megathrust earthquakes: Application to Chile

Seismica
Megaearthquakes (Mw > 8) cause continental-scale, long-lasting surface deformation, mainly due to viscoelastic relaxation of the asthenosphere. To investigate the links between this deformation and the slip history along subduction interfaces—including ...
