Please cite the work as: Kewei Li, Junju Xie, Xiaojun Li, Wenxiang Jiang, Chuanbin Zhu, Yong Zhang. 2025. A 100-meter-resolution site-condition map of China based on surface geology and bedrock depth. Engineering Geology, 354: 108199. https://doi.org/10.1016/j.enggeo.2025.108199.
We proposed a hybrid VS30 prediction method that incorporates geological unit characteristics and bedrock depth to account for physical property variations within the units. By applying this model with regional adjustments based on geological environmental differences, we produced a nationwide 100-meter resolution VS30 map and a same resolution site condition map for China.
1) The 100-meter resolution VS30 map for China is provided in the file VS30_CHN_100.ZIP.
2) The 100-meter resolution Chinese site classification map is provided in the file CHN_CLS_100.ZIP.(Please note that in this map, the values corresponds to the site categories in China as follows: 0 - I0, 1 - I1, 2 - II, 3 - III, and 4 - IV.)
