As early as May 1964, the Department of Geology and Shanghai Municipal People’s Committee jointly held the “Shanghai Ground Subsidence Conference on Hydrogeology and Engineering Geology” to discuss the issue of land subsidence in Shanghai, confirming that the exploitation of groundwater by large amounts of groundwater is the result of land subsidence
