Lithospheric Structures of Marginal Sea Basins in and Around the Philippine Sea Plate Shaped by Eastward Mantle Flow

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Formation of marginal sea basins is generally considered to be closely linked to mantle flow, but it is still ambiguous due to limited evidence from seismic anisotropy. Here, we investigate three‐dimensional shear‐wave azimuthal anisotropy in the lithosphere beneath the Philippine Sea Plate (PSP) and its surrounding regions.

Deep Source Regions for Back‐Arc Volcanism in the Patagonian Slab Window Imaged by Finite Frequency P and SH Body Wave Tomography

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract The subduction of the Chile Ridge beneath South America beginning 12–16 Myr ago opened a gap in the subducting slab beneath southern Patagonia, which migrated northward and is located today at 46°S. Geodynamic processes associated with the slab window are poorly understood.

The influence of observation environment on background noise level of gPhone gravimeter

open access: yesGeodesy and Geodynamics, 2017
Based on the observations of 36 gPhone gravimeters in 2015, the background noise levels in the seismic frequency band (200–600s) and sub-seismic band (1–6 h) are calculated.

The Complex Inner Core Boundary Beneath South America From Seismic Core Phases: Possible Elevated Topography and Fast Crystallization

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Multi‐scale topography and elastic contrasts at the inner core boundary (ICB) are crucial for understanding inner core (IC) growth and outer core (OC) convection. However, most ICB studies focus on the IC's eastern hemisphere, with limited spectral constraints on ICB topography.

Nonstationary Stochastic Simulation of Strong Ground-Motion Time Histories : Application to the Japanese Database [PDF]

open access: yes, 2012
For earthquake-resistant design, engineering seismologists employ time-history analysis for nonlinear simulations. The nonstationary stochastic method previously developed by Pousse et al. (2006) has been updated.

Observational Seismic Fragility Models for Unreinforced Masonry Buildings Based on Building‐by‐Building Damage Data From the 2012 Emilia Earthquakes

open access: yesEarthquake Engineering &Structural Dynamics, Volume 54, Issue 11, Page 2927-2946, September 2025.
ABSTRACT Over recent decades, Italy has been affected by multiple earthquakes, revealing the significant vulnerability of existing structures. These seismic events have resulted in notable human and economic losses, emphasising the importance of evaluating the impact of one or more seismic events on various building types.
