中国地震专家将地震预测划分为四个阶段,即长期(几年到几十年)、中期(几个月到几年)、短期(几天到几个月)和临震阶段(几天之内)。各个阶段将开展以下综合性的研究:(1)长期预测阶段:开展地震活跃期—平静期的研究判定:估计活跃期内的强震主体活动地区及总体水平;确定十年尺度的地震重点监视防御区及重点监视防御城市。(2)中期预测阶段:对地震活动与地震前兆观测的跟踪过程中,出现的
Chinese earthquake experts classified the earthquake prediction into four phases: long term (several years to several decades), mid term (several months to several years), short term (several days to several months), and quake-prone phase Inside). The following comprehensive studies will be carried out in each phase: (1) Long-term prediction phase: conducting seismic active-calm study and judgment: estimating the area and overall level of main activities of strong earthquakes during the active phase; Defense zone and focus on monitoring and defense city. (2) Medium-term prediction stage: During the tracking of seismic activity and earthquake precursor observation,
