  • Earthquake information services require in-depth research on the public reach and feedback. Research on the public earthquake early warning needs and the acceptance of false alarms has recently become sincerely necessary for the earthquake early warning system is about to provide services to the public on a large scale due to the advancement of the national earthquake early warning project. This paper designs a survey index system including public reach rate and public satisfaction to quantitatively measure the public reach and satisfaction of earthquake disaster mitigation services and has achieved good results. The results of the nationwide public survey show that 80.7%, 56.2%, 29.5% and 26.7% of the public have contacted the four services including earthquake quick report service, earthquake knowledge popularization, earthquake resistance consulting service for self-built houses, and information portals of earthquake departments at all levels. The public contact of the services has obvious regional characteristics and group characteristics. The public satisfaction is generally high, but the timeliness satisfaction evaluation score of the earthquake quick report service is relatively low. The public lacks an intuitive experience of its timeliness improvement in recent years. Research on the public demand of earthquake early warning shows that 88.3% of the public believe that it is necessary, 56.8% of the public have a strong demand for it, and the public acceptance of false alarms has remained at a high level in the past ten years. In large cities and the earthquake-prone areas, the public demand for earthquake early warning and the acceptance of false alarms are visibly higher than the overall nationwide level.
