The Cimandiri fault also shows a left-lateral slip, but in the south it shows a thrust fault mechanism. Source mechanism throughout the Lembang fault indicates a left-lateral strike slip in agreement with previous studies. Histograms of travel-time residuals depict good results, in which travel-time residuals are mostly close to zero. In addition, there is another cluster in Garut trending southwest-northeast, which is possibly related to a local fault. There are several clusters of earthquakes at depths ≤ 30 km, which are probably related to the Cimandiri, Lembang, and Baribis faults. The results indicate improved hypocenter locations, where patterns of seismicity in West Java were delineated clearly. We also conducted focal mechanism analysis to estimate the type of fault slip. We then relocated the events using hypocenter double-difference method. Earthquake locations were determined using Hypoellipse code that employs a single event determination method. We determined earthquake locations through re-picking of P- and S-wave arrival times recorded by BMKG network.
