Title: Effects of Potential Earthquakes on Construction and Development in South China Sea Region
Abstract: The South China Sea( SCS) region is rich in oil,gas,and fishery resources,as well as potential tourism sites. With the establishment of the city of Sansha,traffic engineering,civil engineering,and infrastructure construction in the SCS have become the core of the economy. The SCS is located at the intersection of the Eurasia,Pacific,and Indian Plates and has a very complex geological structure. Considering the impact of potential earthquakes on the development of the SCS region,steps need to be taken to mitigate their dangerous effects. China currently has established relatively complete seismic design codes for structures on land,but studies on offshore earthquake engineering are still rare,and attenuation strategies for offshore engineering are incomplete. This paper will analyze the seismotectonics of the SCS and its adjacent areas through analysis of historical seismic data. The results show:( 1) Earthquakes greater than magnitude 7 have occurred in the northern part of the SCS. Thus,offshore engineering in the region should consider the impact of earthquakes related to the Honghe and Qiongyue offshore fault zones.( 2) In the central region of the SCS,the impact of the subduction zone from south Tainan to the west side of the Luzon Island in the Philippines should be taken into account.( 3) The characteristics of subduction earthquakes and shallow crustal earthquakes are different,and it is necessary to study the specific features of interface and intraslab earthquakes in a subduction zone.
