Summary:Abstract The Whitney (2018) linear baseline correction method is used to analyze the near-fault strong motion data of the 1999 Chi-Chi earthquake and quickly calculate the co-seismic displacement. The feasibility of this method is verified by comparison with the coseismic displacement data of adjacent GPS stations. The results show that the coseismic displacement of the hanging wall is significantly larger than that of the foot wall, and largest displacements reached 707.0cm north and 369.7cm up respectively, and occurred at the hanging wall station TCU052. The results in this paper can provide references for the rapid identification of coseismic displacements using strong motion data.
