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

description: 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. Coastal high-velocity anomalies at depth (~30 km) suggest
 localized mantle uplift related to rifting. Moho uplift near the coast,
 together with the asymmetric uplift of the Taebaek Mountain Range,
 indicates depth-dependent lithospheric stretching and isostatic rebound
 during rifting. These observations are consistent with geological evidence
 of East Sea (Sea of Japan) opening, highlighting the offshore rift center
 and its influence on onshore crustal structure. The results provide new
 constraints on rift-related processes, including lithospheric thinning,
 mantle upwelling, and asymmetric rift-flank uplift, demonstrating the role
 of paleo-rift structures in controlling present-day seismicity.
description: 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
