Abstract This paper uses sequence analysis and wavelet spectrum methods to discuss co-seismic deformation waves (CSDW) records characters and its conduct mechanism in Fujian-Guangdong area.The deformation data, based on 10 stations, includes 40 precursory anomalies in total. The result show that: (1) Arrival-time of CSDW is related to epicentral distance, the records include d-P and d-S waves, the records from different items are not consistent, and the same measured items are similar to the recorded waveform. (2) To a certain extent, the amplitude ratio shows the direction of the source, and further reflects the direction anisotropy of the amplitude ratio. (3) By calculating the cross(self)-correlation and filter processing, we can identify the CSDW bands in 0.02~0.04 Hz; the peak value is about 0.025Hz. (4) The wavelet spectrum band of Chile earthquake CSDW is mainly 64~254 s, the main energy is concentrated in 128~254 s, which is different thanthe Nepal earthquake CSDW. Different measuring points are different, the band of Chaozhou and Xiamen station is 16~32 s and 16~64 s, respectively. Results suggest the CSDW records include P wave and S wave elements except surface waves; in addition, the conduction mechanism of CSDW, which is caused by different focal mechanisms, may be anisotropic.This study has reference significance for the study of earthquake induced strain.
