Continent-side paleo-rift structure in the western East Sea (Sea of Japan) and linkage between Moho uplift and mountain range formation

The continental-side paleo-rift structure in the east-central Korean Peninsula is investigated using joint inversion of receiver functions and surface-wave dispersions based on dense seismic networks. The joint inversion analysis provides precise constraints on crustal thickness and Vp/Vs ratios, and high-resolution 3-D shear-wave velocity model. The model reveals distinct lateral and vertical variations associated with tectonic evolution during continental rifting. Inland regions exhibit typical continental crustal thickness (~33 km) and moderate Vp/Vs ratios (1.60-1.75). On the other hand, coastal regions present shallower Moho depths (~24 km), high Vp/Vs ratios (1.8-1.9), and laterally deformed crustal structures to reflect continental-to-oceanic transition. Low-velocity anomalies at shallow depths (≤ 3km) and strong velocity contrasts in the middle and lower crust correlate with sedimentary basins and major faults, indicating tectonic boundaries that influence regional seismicity. C..., , , This dataset is concerned with the paper \"Continent-side paleo-rift structure in the western East Sea (Sea of Japan) and linkage between Moho uplift and mountain range formation\" submitted to Journal of Geophysical Research: Solid Earth by Jeongin Lee, Tae-Kyung Hong, Junhyung Lee, Seongjun Park and Byeongwoo Kim in 2025.

The earthquake waveforms, receiver functions, group velocity dispersion and shear-wave velocity models analyzed in the article are provided.
Also We provide data files to produce three figures in the paper: Figures 10, 11, and 12.

The dataset includes .dat and .sac files.
The .txt files are in ASCII format and can be opened with common text editors (e.g., vi, WordPad).
The .sac files are in sac format and can be processed using seismic data processing tools such as SAC.
If access to SAC software is limited, the Python library ObsPy can be used to read and process .sac files.

Please see the detailed information for the files below.
