Short summary

We obtain the highest-resolution three-dimensional P-wave attenuation model in the China Seismic Experimental Site to date. The P-wave attenuation value anomalies along large fault zones, some basin areas, and the Tengchong volcanic area are low, reflecting the high degree of medium fragmentation in these areas with thick sedimentary layers or rich in fluids.
