Abstract:  The geological processes and their interactions in the earth not only control the formation and evolution of global geological patterns, but also control the formation of geothermal resources and the occurrence of seismic activities. Through systematic investigation and summary, this paper systematically discusses the symbiotic deep driving mechanism of geothermal resources and seismic activities. Firstly, the background of the formation of global high-temperature geothermal and large/ultra-large seismic zones are summarized. Most high-temperature geothermal and large earthquakes overlap in spatial distribution and are formed  at  active plate margins, while medium-low-temperature geothermal is often formed in  plates and accompanied by seismic activities. Secondly, the deep driving factors of the symbiosis between geothermal resources and seismic activity are summarized, and it is found that fluid and fault structure play a crucial role in the release of heat energy and earthquake, and are the main controlling factors of geothermal resources and seismic activity in deep depth. Thirdly , the results of deep geophysical exploration of geothermal resources and seismic activity are summarized, indicating that the homology and causality relationship between geothermal and earthquake can be revealed by magnetotelluric methods, and geothermal and earthquake are derived from the exchange of deep matter and energy. Finally, the research methods and development direction of the deep driving mechanism of the co-occurrence of geothermal resources and seismic activities are prospected.
