Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.Abstract Ribbon collision is a process that can rapidly disturb the symmetry of subduction zones. Previous studies have demonstrated how ribbon collision causes rotation at the surface and contortion in the slab, but have only focused on the surface kinematics.

Asthenosphere Flow Modulated by Megathrust Earthquake Cycles [PDF]
Geophysical Research Letters, 2018 Abstract Subduction megathrusts develop the largest earthquakes, often close to large population centers. Understanding the dynamics of deformation at subduction zones is therefore important to better assess seismic hazards. Here I develop consistent earthquake cycle simulations that incorporate localized and distributed deformation ...

Modeling Geoid and Dynamic Topography From Tomography‐Based Thermo‐Chemical Mantle Convection
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract Mantle convection causes the most important contribution to the geoid and dynamic topography. With mantle density inferred from high‐resolution tomography models and numerical methods solving the governing equations of viscous mantle flow, the modeled geoid can fit the observations well.

Plug flow in the Earth's asthenosphere
Earth and Planetary Science Letters, 2018 Abstract Recent seismic observations, focused on mantle flow below the Pacific plate, indicate the presence of two shear layers in the Earth's asthenosphere. This is difficult to explain under the classic assumption of asthenosphere flow driven by plate shear from above.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract The study of silicate glasses is important to understand the physical and chemical properties of silicate melts under high‐pressure conditions relevant to planetary interiors. We conducted in situ Brillouin spectroscopy measurements on two endmember, low‐impurity CaSiO3 glasses and one Fe, Al, Mg, Ti‐bearing CaSiO3 glass up to 23 GPa.
