Abstract

West Sumatra is one of the regions with a high level of seismicity due to a very active tectonic order. The tectonic system, namely; Subduction zone between the Indian-Australian tectonic plate and the Eurasian plate, Mentawai Fault System (MFS) and Sumatra Fault System (SFS). The accuracy of the location of the earthquake is needed to determine the absolute location of the hypocenter, the method used is the double difference method. The double difference method identifies adjacent earthquake pairs by making travel time corrections at stations. The results of the earthquake hypocenter relocation with the double difference method can obtain a more accurate hypocenter location where, the residual travel time after relocation gets smaller to near zero indicating a better residual value of the relocation results compared to the residual value before being relocated. So, the earthquake parameters obtained are better than before being relocated.Keywords: West Sumatra, Earthquakes, Hypocenter Relocation, Double Difference Method
