Active tectonics of the eastern java based on a decade of recent continuous geodetic observation
The eastern part of Java Island is transversed by major faults such as Cepu, Blumbang, Surabaya, and Waru Segment, part of the Kendeng Fault, Wonsorejo Fault, Pasuruan Fault, and Probolinggo Fault. Due to the major fault, we used decomposition of identified fault from the Global Navigation Satellite...

| description | The eastern part of Java Island is transversed by major faults such as Cepu, Blumbang, Surabaya, and Waru Segment, part of the Kendeng Fault, Wonsorejo Fault, Pasuruan Fault, and Probolinggo Fault. Due to the major fault, we used decomposition of identified fault from the Global Navigation Satellite System (GNSS) observation data to identify the potential of local deformation. We analyzed surface deformation due to the effect of major fault using scaling law and elastic half-space method. We investigated the possibility of unidentified fault using strain rates based on velocity vector data before and after correcting the effect of a major fault. We found that strain calculation for principal strain value in the eastern part of Java Island is less than one microstrain/year and the dominant one with a compression pattern due to the Sunda subduction zone. The maximum shear strain rate value goes from 0.002 to 0.094 microstrain/year, and the dilatation rate value ranges from −0.141 to 0.038 microstrain/year, which correlates with the reverse of the Kendeng Fault. A higher compression pattern outside the major fault in a differential maximum shear strain rate might indicate a local fault. |
