Complex Upper-Mantle Anisotropy Beneath the Pacific Triangle Revealed by Shear-Wave Splitting

Abstract Understanding mantle flow beneath old oceanic plates is essential for linking present-day plate motions with long-term lithospheric evolution, yet direct constraints remain sparse due to limited offshore observations. Here, we investigate upper-mantle seismic anisotropy...

Subsurface fault imaging beneath the Seoul metropolitan area using joint inversion of S-wave travel times and Rayleigh-wave dispersion

Constraining seismogenic fault structures is critical in the densely populated area such as the Seoul metropolitan area of the Korean Peninsula, where historical records document damaging earthquakes. Recent increase in clustered seismicity has highlighted the need for improved c...
