Feedback between megathrust earthquake cycle and plate convergence. [PDF]
Sci Rep, 2023 : Over million years, convergence between the Nazca and South America tectonic plates results in Andean orogeny. Over decades/centuries, it fuels the earthquake cycle of the Andean megathrust.

Cascading rupture of a megathrust
Science Advances, 2022 Understanding variability in the size and location of large earthquakes along subduction margins is crucial for evaluating seismic and tsunami hazards. We present a coseismic slip model for the 2021 M 8.2 Chignik earthquake and investigate the relationship of this earthquake to previous major events in the Alaska ...

Unraveling Megathrust Seismicity [PDF]
Eos, Transactions American Geophysical Union, 2013 The majority of global seismicity originates at subduction zones, either within the converging plates or along the plate interface. In particular, events with Mw ≥ 8.0 usually occur at the subduction megathrust, which is the frictional interface between subducting and overriding plates.

Megathrust locking encoded in subduction landscapes. [PDF]
Sci AdvLocked areas of subduction megathrusts are increasingly found to coincide with landscape features sculpted over hundreds of thousand years, yet the mechanisms that underlie such correlations remain elusive. We show that interseismic locking gradients induce increments of irreversible strain across the overriding plate manifested predominantly as ...

Geochemistry, Geophysics, Geosystems, 2023 The seismic hazard related to megathrust earthquakes in the Ryukyus (southern Japan) is poorly constrained as no large earthquake has been reported there.

Earthquake Fingerprint of an Incipient Subduction of a Bathymetric High
Geophysical Research Letters, 2022 The resistance of bathymetric highs to subduction results in large‐scale morphological distortions of the outer‐rise, trench, and fore‐arc regions. Once subducted, bathymetric highs induce frictional segmentation along the plate interface that may result

Geochemistry, Geophysics, Geosystems, 2022 The causes for forearc basin and megathrust rupture zone segmentation are controversial. The Nankai forearc, Japan, is separated into five domains based on topography: Enshu, Kumano, Muroto, Tosa, and Hyuga.

Modelling the seismic potential of the Indo-Burman megathrust [PDF]
Scientific Reports, 2021 AbstractThe Indo-Burman arc is the boundary between the India and Burma plates, north of the Sumatra–Andaman subduction zone. The existence of active subduction in the Indo-Burman arc is a debatable issue because the Indian plate converges very obliquely beneath the Burma plate.

Mega-earthquakes rupture flat megathrusts [PDF]
Science, 2016 Mega-earthquakes go the flat way Megathrust faults in subduction zones cause large and damaging earthquakes. Bletery et al. argue that certain geometric features of the subduction zones relate to earthquake size. The key parameter is the curvature of the megathrust.

Determination of tsunami run-up and golden time in the megathrust subduction zone of the sunda strait segment [PDF]
E3S Web of Conferences, 2021 The Indonesian Disaster Data and Information Management Database state that the tsunami in the Megathrust Subduction Zone of the Sunda Strait Segment is a disaster threat with high impact and loss of life every time it occurs.
