Current status and prospect of the deep structure exploration of the littoral fault zone in the northern South China Sea
The littoral fault zone (LFZ) in the northern South China Sea, is an important boundary fault between South China sub-plate and South China Sea sub-plate, is the seismogenic structure in the northern continental margin, and acts as a basin-controlling fault in the Pearl River Mouth Basin. Studies on the deeper crustal structures, structural evolution, and the latest activities of the LFZ have great significance in understanding the structural architecture and geodynamic processes, and in seismic hazard assessment. We review the deep structure exploration, tectonic attributes, activities, and seismogenic structure of the LFZ. Based on these, we propose that the LFZ is segmented concerning the deeper crustal structures and active characteristics; moreover, it has the potential of strong earthquakes when all three components of the LFZ, a NW-striking fault, and a low-velocity layer meet together. Finally, we highlight the problems to be solved in the future about the LFS, including the coupling of the deep and shallow structures, the relationship with the intersected NW-striking faults, the latest activities, and the assessment of earthquake-tsunami disasters.
