摘要

选取2004-01～2007-11共180多个速报地震,经震中距校核后测算的MS震级与全国大震速报台网发布的MS震级比对,得出泉州台在震级测算方面的偏差情况。并根据不同地震的相应特征,确定相应的震级校正值,以此提高泉州台的地震速报精度及作为提供日常处理地震资料数据的技术依据。
The paper selects more than 180 promptly reported earthquakes from January 2004 to November 2007,and compares the MS Values of the said earthquakes(after epicentral distance checking) with those released by the National Large Earthquake Prompt Report Network,so as to find out the deviation of Quanzhou Seismostation in magnitude measurement and calculation.Furthermore,it also determines the corrected magnitude values in view of the corresponding earthquake features,expecting to improve the accuracy of earthquake prompt report of Quanzhou Seismostation and offer technical basis for daily seismic data processing.
