【摘要】 选用福建地震台网"十五"观测系统正式运行以来记录的台湾地区M L≥3.0地震资料,计算了福建与台湾地震台网测定震级平均偏差、相关系数及拟合方程,并分析了震级差异形成原因。结果表明,福建地震台网测定台湾及其邻近海域的震级偏低,3.0≤M L<4.5,偏差量为0.80,M L≥4.5,偏差量为0.46;量规函数偏小是造成震级偏低的主要原因。更多还原

【Abstract】 Based on ML≥3.0 earthquakes which are recorded by Fujian"the ninth five-year plan"Seismic network,we calculated the magnitude average deviation,correlation coefficient,fitted equation of magnitude determination by Fujian and Taiwan seismic network,and analyzed the causes of magnitude discrepancy forming.The result shows less deviation of Taiwan and adjacent sea microseisms magnitude determined by Fujian seismic network,3.0≤ML<4.5,deviation value is 0.80;ML≥4.5,deviation value is 0.46;Small calibration function is the main reason to the low magnitude.更多还原
