【摘要】 濮阳市地震台位于豫北的东北部,其东部的40平方千米为东濮凹陷和聊兰断裂带,这一区域地震较多。濮阳台计算出的震级与省台网震级相比普遍偏低,严重影响我台地震速报的正确性。经过分析该区域地震偏低的原因,认为加校正值是比较好的应对方法,并计算出了本区域地震震级的校正值。通过使用,效果良好。更多还原

【Abstract】 Puyang Seismic Station is located in the northeast of North Henan.40 km east of the part are the Dongpu Sag and Liaocheng-Lankao Fault Belt,with many earthquakes in history.The calculation of earthquake magnitude in Puyang Seismic Station is lower than that in other stations,influencing the correctness of earthquake report.After analyzing the reasons,a correction value is a relatively good coping method.The correction value of earthquake magnitude for the area is calculated,which has been proved to be working well.更多还原
