Downdip Variations in Megathrust Seismogenic Behavior in the Japan Trench Subduction Zone Affected by Mantle Wedge Serpentinite

Geophysical Research Letters
It is important to seek geological context for the geophysically observed downdip segmentation of seismogenic behavior of subduction megathrusts. Here we focus on how mantle wedge serpentinite may affect megathrust seismogenesis at Japan Trench—an end ...

Rupture Depth-Varying Seismicity Patterns for Major and Great (M_W ≥ 7.0) Megathrust Earthquakes [PDF]

, 2017
Large earthquakes on subduction zone plate boundary megathrusts result from intervals of strain accumulation and release. The mechanism diversity and spatial distribution of moderate-size aftershocks is influenced by the mainshock rupture depth extent ...

Coseismic Slip and Early Afterslip of the 2024 Hyuganada Earthquake Modulated by a Subducted Seamount

Geophysical Research Letters
Subducted rough topography complicates seismic and aseismic slip behavior. The 2024 M 7.1 Hyuganada earthquake occurred along the megathrust with ridge subduction.

The 2017 M_W 8.2 Chiapas, Mexico Earthquake: Energetic Slab Detachment [PDF]

, 2017
On 8 September 2017, a great (M_w 8.2) normal faulting earthquake ruptured within the subducting Cocos Plate ~70 km landward from the Middle American Trench beneath the Tehuantepec gap. Iterative inversion and modeling of teleseismic and tsunami data and

Testing Megathrust Rupture Models Using Tsunami Deposits

Journal of Geophysical Research: Earth Surface
AbstractThe 26 January 1700 CE Cascadia subduction zone earthquake ruptured much of the plate boundary and generated a tsunami that deposited sand in coastal marshes from northern California to Vancouver Island. Although the depositional record of tsunami inundation is extensive in some of these marshes, few sites have been investigated in enough ...

Temperature insensitive viscous deformation limits megathrust seismogenesis

Earth and Planetary Science Letters
Three models have been proposed to explain the downdip limit of the subduction seismogenic zone. The first is a temperature-controlled transition in rate-and-state frictional properties between 350–510°C, which inhibits earthquake nucleation. The second places the limit at the frictional and viscous failure envelope intersection.

On Dislocation Modeling of Megathrust Tsunami Sources

Journal of Geophysical Research: Solid Earth
AbstractModeling tsunamis due to subduction earthquakes for scientific research and hazard assessment requires accurate quantification of coseismic seafloor deformation. Although the widely used analytical model of shear dislocation in a uniform elastic half space can accommodate complex fault geometry and slip distribution, it fails to capture the ...
