Based on strong motion observation data record by the Hebei strong motion network, 32 ML
≧3.0 seismic events are located using MSDP software localization method. The located epicenter parameters are contrastive analysis with the formal earthquake catalog results. The analysis shows that? the locating results using the strong motion observation data can meet the requirements of earthquake location has good consistency with the formal earthquake catalog. Using strong motion observation data as addition data for earthquake quick report and earthquake warning has positive significance to their accuracy.
