Seismic Imaging Reveals Ongoing Modification of Craton Margins in Northeast Asia
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Cratonic margins are commonly modified, yet the processes responsible remain debated. The Korean Peninsula, situated between adjacent cratons, the Japan Trench, and a back‐arc system, provides a natural setting to investigate this problem. Using 4 years of dense seismic observations, we image upper‐mantle structure beneath the peninsula with P‐

DEEP STRUCTURE OF ORE DISTRICTS OF THE FENNOSCANDIAN AND UKRAINIAN SHIELDS
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017 New interpretation of geological and seismic data has revealed a correlation of surface structures of large endogenous ore districts of the Fennoscandian and Ukrainian shields with Moho topography and local crustal inhomogeneities. As a result, models of

Tectonic evolution of a continental collision zone: A thermomechanical numerical model [PDF]
, 2004 We model evolution of a continent-continent collision and draw some parallels with the tectonic evolution of the Himalaya. We use a large-scale visco-plasto-elastic thermomechanical model that has a free upper surface, accounts for erosion and deposition

Effects of Topography on Seismic-Wave Propagation: An Example from Northern Taiwan [PDF]
, 2009 Topography influences ground motion and, in general, increases the amplitude of shaking at mountain tops and ridges, whereas valleys have reduced ground motions, as is observed from data recorded during and after real earthquakes and from numerical ...

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

Sensitivity of seismic wide‐angle wave‐field and first arrival times to fine scale crustal structure and moho topography [PDF]
Geophysical Research Letters, 1999 A sensitivity study of stochastic crustal and Moho models on Moho refracted first arrivals is presented. The crustal model is a self‐affine velocity structure superposed on a linear velocity gradient. The Moho is represented by a first‐order discontinuity with a topography which is also self‐affine. The sensitivity of both travel‐time and wave‐field is

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.

Tectonophysics, 2015 Crustal thickness maps at regional scales are typically compiled using estimations inferred from different geophysical datasets providing a variable coverage of the investigated area. Consequently, spurious effects related to changes in data resolution or artifacts in grid interpolation may affect significant zones of those maps.

Investigating the kinematics of mountain building in Taiwan from the spatiotemporal evolution of the foreland basin and western foothills [PDF]
, 2006 The Taiwanese range has resulted from the collision between the Luzon volcanic arc and the Chinese continental margin, which started about 6.5 Myr ago in the north, and has since propagated southward.

Autocorrelation Seismic Imaging of Northern Taiwan Using Ambient Noise Data
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Over the past few million years, northern Taiwan records a tectonic history of subduction to arc–continent collision followed by post‐collisional collapse. This evolution motivates constraints on crustal structure, including crustal layering and thickness.
