【摘要】 地震的基本参数是一切有关地震研究的基础，尤其是震中及震级是工程地震研究最重要的基础数据。对于特定的工程场地和研究区域，某些地震震中的位置，对地震构造环境的评价，潜在震源区的划分起着举足轻重的作用。笔者曾对诸多地震进行过甄别与修定，并总结出５条基本原则。更多还原

【Abstract】 Fundamental parameters of earthquakes are the basis of all seismological researches,especially,the epicenter and magnitude of an earthquake are the most important basic data of engineering seismicresearch,and play a decisive part in specific engineering sites and research regions. The epicentral frycanons of some earthquakes play an important part in the evaluation of seismotectonics environment,zoning of potential source region.The author of this paper has discriminated and modified a lot of pa-rameters of historical earthquakes and has summed up five fundamental principles there of’更多还原
