Abstract Combined with single-day vertical displacement from GPS and environmental load deformation data, this paper analyzes the surface deformation characteristics of typhoon Mangkhut at continuously operating reference stations in Hong Kong from September 9 to 23, 2018. Both data processing results show that the ground surface of Hong Kong has a certain degree of settlement during the typhoon. The overall variation is that as vertical distance from Hong Kong is closer, the impact of the typhoon on surface subsidence in Hong Kong area increases. The two methods are more consistent in the trend of vertical surface deformation, but there are differences in the values, mainly for two reasons: 1) The surface vertical displacement calculated by GPS in a short period of time includes the influence factors of temperature, latitude, and solution error; 2) Due to the lack of relevant information on surface water and groundwater, there are large errors when the model simulates the influence of various factors on surface water and groundwater.
