3-D numerical modelling of the feedback between deformation and thermal structure during subduction initiation for the French Lesser Antilles
We used 3-D thermomechanical modelling to investigate conditions during subduction-zone initiation and early thermal development with focus on the Lesser Antilles. Our model imposes a convergence velocity of 2 cm per year and incorporates heating caused by irreversible deformation of mantle and crustal rocks, using ela...

Convergence and Residual Error Analysis of Unsteady MHD Stagnation Flow Over a Cylindrical Surface With Streamline and Isotherm Visualization
Melting phenomena are important in geothermal heat exchangers, magmatic crystallization, and future thermal energy storage systems. This study provides a detailed numerical study of the heat and mass transfer behavior of unsteady MHD Cross nanofluid flow over a stretching melting cylinder in a Darcy–Forchheimer por...

The Impact of Double Subduction on Plate Velocity and Euler Pole Shifts: Insights From Spherical Subduction Models
Same‐dip double subduction (SDDS), in which two parallel slabs dip in the same direction, has been linked to accelerated plate motion in both modern and ancient convergent systems, such as the Late Cretaceous Africa–Eurasia system. Yet a systematic framework for quantifying how SDDS alters plate kinematics in a large‐s...

3-D thermomechanical geodynamic modelling of heating and volcanism in the Massif Central (France) and Eifel Volcanic Region (Germany)
The French Massif Central and the Eifel Volcanic Field represent two of the enigmatic features in France and Germany, respectively. Both areas have been affected by Cenozoic volcanism whose origin is still debated. Using 3-D numerical geodynamic modelling of recently developed solid-mechanical constitutive laws includi...

Numerical simulation of unsteady MHD bio-convective flow with Cattaneo-Christov heat flux over a stretching surface
Abstract The unsteady, two-dimensional, laminar boundary-layer flow of a viscous nanofluid containing gyrotactic microorganisms is examined over a permeable, radiative stretching sheet subject to an inclined magnetic field, Darcy resistance, internal heat generation, wall mass suction, velocity slip and convective ther...

Implications of Thermal Weakening and Magma Compressibility for Volcano Monitoring
Magmatic intrusion and volcanic deformation are traditionally approximated with an inflating cavity in an elastic halfspace. Various analytical models predict surface displacement as a function of pressure or volume change, depth, and elastic crustal properties. While this approach allows for rapid inversion of monitor...
