Seismotectonics of Ghana and adjacent regions in Western Africa: A review

Earthquake Research Advances
Ghana and its surrounding West African region are often regarded as a stable intraplate area far from active plate boundaries, characterized by relatively low seismicity compared to tectonically active zones like the East African Rift.

Geodynamic Significance of Intraplate Basaltic Magmatism From the Western Mediterranean Region

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Dynamic topography changes as mantle convection evolves, making its past surface expression difficult to reconstruct. Widespread Neogene‐Quaternary intraplate basaltic magmatism across the Western Mediterranean Region allows us to test whether dated basalts preserve the mantle thermal structure responsible for regional dynamic support.

Investigation of coupling between surface processes and induced flow in the lower continental crust as a cause of intraplate seismicity

Many studies have highlighted the role of coupling between surface processes and flow in the lower continental crust in deforming the crust and creating topographic relief over Quaternary timescales.

Fifty Years Later: Revisiting Viking 2 Seismic Signals Through InSight

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract For nearly 50 years, the origin of the candidate seismic signals recorded by Viking 2 remained unresolved because of limited instrumental sensitivity, onboard observation, data compression, and the absence of Martian seismic context. Here we reconstruct the Viking seismic workflow and reinterpret the two Viking candidate events, recorded on ...

Influence of Glacial Isostatic Adjustment on Intraplate Stress and Seismicity in Eastern North America in the Presence of Pre‐Existing Weak Zones

Geochemistry, Geophysics, Geosystems
Eastern North America has hosted significant historical earthquakes, where seismicity clusters along tectonically inherited structures. Using the spherical finite‐element code CitcomSVE and fully 3D viscosity structure, we model the intraplate stress ...

Atypical Linear Tectonic Block of the Intraplate Deformation Zone in the Central Indian Ocean Basin

Journal of Marine Science and Engineering
The Central Indian Ocean Basin (CIOB) is distinguished by unusually high tectonic activity, setting it apart from all other passive oceanic basins. Within the interior of the Indo-Australian lithospheric plate lies a unique area of intraplate deformation.

OIB‐Type Garnet Amphibolites From the Xuerongzangbu Area, Central Lhasa Terrane, Tibet: Implications for Songduo Paleo‐Tethys Ocean Evolution and Permian Mantle Activity Along North Gondwana

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Whether the Songduo metamorphic belt represents an in situ Paleo‐Tethyan suture within the Lhasa Terrane or far‐traveled allochthonous high‐pressure slices, and how Permian mantle activity along the North Gondwana margin relates to subsequent Tethyan evolution, remain central questions in Tibetan tectonics.

BaSIC: A Bayesian Inversion Model for Basalt Source Investigation and Characterization

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract We present BaSIC: Basalt Source Investigation and Characterization, an open‐source Python based Bayesian inversion method to constrain the source mineralogy of basalts. Using bulk rock geochemistry, the model takes the averages and standard deviations of six elemental ratios (Mn/Fe, Zn/Fe, Mn/Zn, Sc/Zn, Co/Fe, and Ga/Sc) for a given basalt ...

Application of Linked Stress Release Model To Historical Earthquake Data: Comparison Between Two Kinds of Tectonic Seismicity [PDF]

, 2000
The linked stress release model, incorporating a slow buildup of stress within a seismic region, its stochastic release through earthquakes and transfer between seismic regions, is applied to fit historical data from two typical kinds of seismicity ...
