摘要
采用重力资料系统处理,确认广西灵山地区深部存在近EW向、NW向、NE向三组断裂,它们的深度均可达到40 km,近EW、NW向断裂的强烈活动是1936年灵山63/4级地震发生的主要原因。
Using the processing system of gravity data,this paper shows the existance of three group faults with direction of EW,NW and NE in deep area in Lingshan region of Guangxi.The depth of the three faults can be up to 40 km.The strong activities of EW and NW faults is the major reason of the earthquake with M=63/4 occurred in 1936.
