Abstract：Through regional and near-field seismic activity analysis and seismic tectonic environment evaluation,the activity level of far-field earthquakes and near-field earthquakes was studied,and the occurrence conditions of moderate-strong earthquakes in the region were evaluated.In this paper,the fault investigation and activity identifi-cation in the near field area were carried out to explore the distribution,scale and latest activity era of active faults.Based on the empirical relationship between fault rupture length and magnitude,the maximum potential magnitude of active faults was calculated,the setback distance for the active faults was proposed,and the dislocation effect of seismic faults at the site was evaluated.A set of plans for site selection and active fault avoidance of major proj-ects in Fuzhou City is proposed.
