Linking megathrust earthquakes to brittle deformation in a fossil accretionary complex [PDF]
, 2015 Seismological data from recent subduction earthquakes suggest that megathrust earthquakes induce transient stress changes in the upper plate that shift accretionary wedges into an unstable state.

Eos, 2018 The past few decades have seen a number of very large earthquakes at subduction zones. Researchers now have an array of advanced technologies that provide insights into the processes of plate movement and crustal deformation. A review article recently published in Reviews of Geophysics pulled together observations from different locations worldwide to ...

DONET: A Real-Time Monitoring System for Megathrust Earthquakes and Tsunamis Around Southwestern Japan [PDF]
Oceanography, 2014 DONET (Dense Ocean floor Network for Earthquakes and Tsunamis; https://www.jamstec.go.jp/donet/e/index.html) is a cabled seafloor observatory that monitors the Nankai and Tōnankai seismogenic zones, offshore southwestern Japan, in real time. In 1944, two

Seamount Subduction and Megathrust Seismicity: The Interplay Between Geometry and Friction
Geophysical Research Letters, 2023 AbstractSubducting seamounts are recognized as one of the key features influencing megathrust earthquakes. However, whether they trigger or arrest ruptures remains debated. Here, we use analog models to study the influence of a single seamount on megathrust earthquakes, separating the effect of topography from that of friction.

Seismicity and seismic imaging of the Alaska megathrust fault [PDF]
, 2016 The largest earthquakes and the majority of the seismic energy are released on megathrust faults in subduction zones. The goal of this dissertation is to characterize the seismic behavior, structural and physical properties of the megathrust fault, so ...

Megathrust earthquakes: Inferences from numerical modelling and explainable artificial intelligence
, 2023 Our understanding on the main controls of megathrust seismicity is far from complete, particularly on how modelling the system in 3D affects the related dynamics.

JGEET: Journal of Geoscience, Engineering, Environment and TechnologyThe southern coastal area of West Java, particularly Pangandaran, faces a high risk of tsunami disasters triggered by megathrust earthquakes. However, current evacuation strategies in the region often lack integration between seismic hazard analysis ...

Boreas, EarlyView.The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Geophysical Research Letters, 2022 A smooth subducting seafloor usually leads to a smooth megathrust, which promotes great earthquakes. We present a case study at the northern Manila Trench to emphasize that the process depends also on sediment accretion and deformation.
