Quantum gravimeter is a new type of absolute gravimeter that has been rapidly developed in the past 30 years. At present, the research on this new type of gravimeter has entered the stage of miniaturization and practical applications. The applications in the fields of earth science research based on quantum gravimeters at home and abroad have been developed rapidly, including volcanic activity monitoring, marine absolute gravity measurement, and airborne absolute gravity measurement, etc. The ZAG-E type of quantum gravimeter developed by our laboratory has the advantages of small size, easy handling, and high stability. Its absolute gravity measurement accuracy can reach 10 μGal. Based on this quantum gravimeter, our team has carried out related research on continuous absolute gravity measurement at seismic stations, focusing on the continuous absolute gravity measurement performed at the Yanzigou Seismic Station in Ganzi Tibetan Autonomous Prefecture, Sichuan Province. These studies are helpful for the construction of the gravity data of the area and the analysis of the geological topography and the geological activities. The precision gravity measurement based on quantum gravimeters can provide a new method for the research of earth science, and it can also provide reliable absolute gravity data. In the future, quantum gravimeters are expected to be more and more widely used in geosciences such as geophysics and absolute gravity surveying and mapping on the surface.
