Research on the relocation of an earthquake hypocenter using the Double-Difference method has been carried out with a 2015-2019 earthquake case study in Bengkulu Province. The purpose of this study was to determine the change in the position of the earthquake hypocenter before and after relocation using the Double-Difference method, then to determine the RMS (Root Mean Square) value of the residual hypocenter after being relocated using the double-difference method. This research was conducted at the Class III Geophysical Station Kepahiang, Bengkulu at the coordinates of 102 ° -106,5 ° S and -6,5°-1° East Longitude. The research was conducted using the Double-Difference method, namely by using the travel time data between earthquake pairs to an earthquake recording station (earthquake catalog) and using a local velocity model combined with the AK-135 global velocity model. The stages of data processing in this study include the first, namely the process of data preparation where the data used in this study are earthquake hypocenter data, earthquake recording station data, and 1-D velocity model data. Then the research data preparation process is the process of adjusting the earthquake catalog data format into input data in the ph2dt program with the extension * .pha. Furthermore, the data processing uses the hypoDD program with the Double-Difference method in which in this process the researcher has successfully relocated 715 earthquake events from as many as 733 initial earthquake events recorded. From these results it can be used for further seismic studies such as seismic tomography studies and earthquake mitigation studies in the Bengkulu region. Keywords: hypoDD, Double-Difference, 1D Global Speed, AK-135.
