Abstract In this study, we reveal the deformational structure of crust northern part Ryukyu Arc and Okinawa Trough using ambient noise tomography. Compared with southern Ryukyu, segment exhibits a wide shallow basin, without localized thinning, slow extension rates, highly arc‐oblique, right‐lateral retreat Arc. We present both isotropic azimuthally anisotropic shear‐wave velocity models data recorded by an ocean‐bottom seismometer array nearby island stations. The model demonstrates...
Rifting along southeastern Eurasia in the Late Cenozoic led to formation of a magma-poor rifted margin facing South China Sea southeast and Philippine east. Further rifting outer part during middle late Miocene was accompanied by an extensive episode intraplate flood volcanism that formed Penghu Archipelago. Previous geophysical studies area strait have focused primarily on shallow structures rift basins depth Moho. In this study we present regional-scale 3-D S wave structure Taiwan Strait...
Abstract In this study, we revisit the shear‐wave velocity structure of lithosphere and asthenosphere surrounding Hawaiian hotspot swell using Rayleigh wave data spanning periods 20–125 s from PLUME project. A primary goal investigation is to probe origin mechanism that elevates topography, providing insights into mantle dynamics beneath swells. shear model, 30–70 km depth range largely featureless with weak local anomalies, indicating elevation cannot be attributed upper lithospheric...
M w 6.4 Meinong earthquake occurred on 6 February 2016 in southern Taiwan, resulting more than one hundred casualties and several collapsed buildings.The aftershocks mostly at mid-to-lower crustal depths (10 -30 km), related to a blind fault system.However, centimeters of cosesimic surface uplift within the Liushuang, Erhchungli, GutingKeng Formations, composed mainly mudstone, was recorded from InSAR results.The uplifted pattern is similar that GPS leveling data 2000 -2010, which indicates...
The Meishan-Chiayi area of western Taiwan has a large probability producing major earthquake in the near future. Historically, one largest and most damaging Taiwan's earthquakes occurred there. It is, therefore, important to have well-constrained upper crustal 3-D shear-wave velocity model that can be used accurately determine ground motion predictions fault geometry models seismic hazard risk modelling. In this study, we carried out an ambient noise tomography experiment using 100...
