Characterize the structural architecture, timing, and faulting behavior of the western Java Back-arc Thrust to improve regional geohazard evaluations.
Integrated morphotectonic mapping, seismic reflection profiles, and electrical resistivity imaging.
Conducted structural kinematic field surveys and paleoseismological trench excavations.
Dated sedimentary layers using optically stimulated luminescence and radiocarbon methods.
Documented fault activity from the Pliocene to Recent, modulated by structural interactions with volcanoes and sedimentary basins.
Identified late propagation of the thrust network into the Jakarta Basin since the Late Pleistocene, forming immature transpressive structures.
Confirmed elevated seismic hazards along the fault trace capable of historical earthquakes up to magnitude 7 Mw.
