Resulting data from the 2021 campaign in the Seoul metropolitan area (South Korea). Around 40 km of high-resolution reflection seismic data were acquired along an E-W profile cross-cutting major crustal scale fault systems. The raw data were obtained with 2 seismic vibrators as source and 421 10 Hz geophones as receivers, with an asymmetric split spread and roll-along geometry. The acquired data has been processed with Globe Claritas software and it is provided in a standard seg-y format. A full description of the data aquisition is provided in: Samuel Zappalá, Alireza Malehmir, Tae-Kyung Hong, Christopher Juhlin, Junhyung Lee, Myrto Papadopoulou, Bojan Brodic, Seongjun Park, Dongchan Chung, Byeongwoo Kim, & Jeongin Lee. Crustal-scale fault systems in the Korean Peninsula unraveled by reflection seismic data, Earth and Space Science, submitted However, the methodology is the same as used in the previous study: Malehmir, A., Hong, T.-K., Lee, J., Zappalá, S., Brodic, B., Chung, D., Kim, B., Park, S., Lee, J., & Kil, D. (2022). Fault intersections control short period intraplate start-stop seismicity in the Korean Peninsula. In Tectonophysics (No. 229387; Vol. 834). https://doi.org/10.1016/j.tecto.2022.229387 In the dataset are present: - 2 examples of receiver gathers raw: (korea2021_P3_rec1185_raw.segy and korea2021_P3_rec487_raw.segy). - the same 2 receiver gathers after the applied processing: (korea2021_P3_rec1185_raw_rfst_fils_res_tm.segy and korea2021_P3_rec487_raw_rfst_fils_res_tm.segy). - stack section acquired with wireless receivers (20 m spacing), unmigrated and migrated:(korea2021_P3_stack.segy and korea2021_P3_migrated.segy). - stack section acquired with wireless receivers (20 m spacing) with an applied cross dip correction for 10 degrees towards north, unmigrated and migrated: (korea2021_P3_crossdipcorrected_stack.segy and korea2021_P3_crossdipcorrected_migrated.segy). - unmigrated stack section acquired with landstreamer receivers (2 m spacing): (korea2021_P3_streamer_stack.segy.
