a Map view of the study region (red rectangle, inset) showing earthquakes (colored dots: depth scale), active volcanoes (red triangles), and tectonic features. Slab geometry (black dashed contours: Slab2.0 model34), major block boundaries (black lines), and cross-section profiles (A–F: blue lines; 1–6: dashed light blue lines, Supplementary Fig. 15) are annotated. The Pacific Plate’s motion relative to Eurasia is indicated (blue arrow). Abbreviations: NC (North China Block), SC (South China Block), PSP (Philippine Sea Plate). b–g Vertical cross-sections of seismicity along profiles A–F in (a), with earthquake depths color-coded as in (a). Source data are provided as a Source Data file.
