【摘要】 选取2012年3月1日至12月31日临汾市地震台网记录到可精确定位的网外地震,并对每个地震进行重新定位,将结果与山西地震台网的记录进行比较,分析两台网在不同震级范围、不同经纬度的震级偏差情况,找到两台网所定震级的关系,给出多个关系式,用以修正临汾台网的震级,提高准确度。更多还原

【Abstract】 The earthquakes occurred outside network with precise location,recorded in Linfen Seismic Network from Mar.1st to Dec.31 st,2012,are recalculated and are compared with results from Shanxi Seismic Network.The deviations of magnitudes between two networks are analyzed in different magnitude ranges and different positions to figure out the relationship of magnitudes determined by two networks.Several relations are given to correct the magnitudes determined by Linfen network and to improve accuracy.更多还原
