Continent-side uplifted mantle and geological imprints along a paleo rift in the western East Sea (Sea of Japan)

Recent public concern about potential seismic risk in the central Korean Peninsula has provoked preparedness for seismic hazard mitigation. We investigate the seismic velocity structures of the lithosphere in the central Korean Peninsula using ambient noise tomography and earthquake-based Eikonal tomography based on dense seismic networks. We determine Rayleigh-wave group velocities at periods of 1-15 s from ambient noise tomography and Rayleigh-wave phase velocities at periods of 20-80 s from earthquake-based Eikonal tomography. We determine a 3-D shear-wave velocity model in the lithosphere from the Rayleigh wave velocities. The model exhibits high lateral variations ranging from ∼-9 % to ∼8 %, depending on depth. The shear-wave velocities at shallow depths (≤ 2 km) are relatively high in mountain regions and low in coastal and basin regions. Strong velocity contrasts are observed around major earthquake hypocenters at depths of 3-20 km, which may be due to the presence of seismogenic..., , , This dataset is concerned with the paper \"Continent-side uplifted mantle and geological imprints along a paleo rift in the western East Sea (Sea of Japan)\" submitted to Journal of Geophysical Research: Solid Earth by Seongjun Park and Tae-Kyung Hong in 2024.

The interstation ambient-noise crosscorreation functions, earthquake waveforms, and Rayleigh-wave and shear-wave velocity models analyzed in the article are provided.

The dataset includes .dat and .mseed files.
The .dat files are in ASCII format and can be opened with common text editors (e.g., vi, WordPad).
The .mseed files are in miniSEED format and can be processed using seismic data processing tools such as mseed2sac and ObsPy.
