统计地震学在京津冀地区地震危险性评估中的应用
Application of Statistical Seismology to Seismic Risk Assessment in Beijing-Tianjin-Hebei Region
摘要
Abstract
We use the catalog of modern earthquakes in the Beijing-Tianjin-Hebei region from 1980 to 2022 as a statistical sample.To grid the study area,we use the incompletely centralized Voronoi seg-mentation method based on spatial segmentation.Based on the Poisson model,the probability model of earthquake risk is established,and we conduct the probability prediction of small and medium earthquakes at the medium-term scale of the study area.The results show that the calculated probabil-ity of relatively high value region has a certain correlation with the occurrence of earthquakes with Ms≥3.0,which can provide a reference for medium and long term earthquake prediction.关键词
