Abstract:In this paper, we present the EPDAPS system, which was originally dedicated to the data processing and automatic mapping of a borehole strain and gravity time series based on the MATLAB platform. EPDAPS follows the design code of the earthquake precursor database and configures and manages the basic information of the database, such as the database information, station code, and item components. The system can perform data pre-processing, and can also integrate many common deformation data analysis methods, including time-frequency analysis, wavelet analysis, and frequency spectrum analysis, among others. In this paper, we first describe the main frame structure of the system, and then we present the correcting tools dealing with raw data. Finally, we present an example of spectral analysis based on the software. In conclusion, it was found that the system had strong expansibility and compatibility; therefore, the efficiency of daily deformation data analysis and processing can be improved and thus provide powerful support to an earthquake emergency consultation.
