One of the major difficulties in seismic exploration is retaining the vector field information while making full use of multi-component seismic data to describe subsurface media.The development of multi-component seismic data processing based on quaternion were summarized in this study.First, the quaternion and the quaternion forms of multi-component seismic data were briefly introduced.Then, the application of quaternion in multi-component seismic vector data were discussed, and the findings showed that it continues to remain in the stage of exploration.By combining conventional single-component seismic data processing technology with quaternion, vector information and weak signals can be better preserved in the processing of multi-component data.The relative amplitude of each component is also retained.Future research should focus on establishing a complete vector seismic data processing technique based on extended scalar processing using quaternion.
