Seismogenic Fault Reactivation in Western Central Africa: Insights From Regional Stress Analysis

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The onshore continental margins of western Central Africa have been hosting potentially damaging earthquake events for decades; yet, the links between the seismicity, the contemporary stress field, and pre‐existing faults are not well understood.

Lateral propagation–induced subduction initiation at passive continental margins controlled by preexisting lithospheric weakness

open access: yesScience Advances, 2020
Subduction initiation at weakened passive continental margin could be induced by lateral propagation of existing subduction zones. Understanding the conditions for forming new subduction zones at passive continental margins is important for understanding

Landside hazard on the Norwegian continental margin

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле
Numerous landslides are located on the passive margin of Norway. According to the landslides number and the extent of their detachment zones, the margin can be divided into three segments (from south to north) — Scandinavian, Barents Sea and Svalbard ...

Slab Pull Driven South China Sea Opening Implies a Mesozoic Proto South China Sea

open access: yesGeophysical Research Letters, 2023
Most paleo‐reconstruction models agree that the South China Sea (SCS) opens within a continental domain located at the trailing edge of the subducting plate of a vanished ocean named Proto South China Sea (PSCS).

Estimation of the gas hydrate saturation from multichannel seismic data on the western continental margin of the Chukchi Rise in the Arctic Ocean

open access: yesFrontiers in Earth Science, 2022
A multichannel seismic survey was conducted to investigate the geophysical characteristics of gas hydrates along the western continental margin of the Chukchi Rise around an ARAON mound cluster, which was first recovered in 2016. In the seismic data, gas
