【摘要】 选取了2008年5月12日四川汶川8.0级主震及5月份发生在陕西省M≥2.5级、四川省M≥4.0级余震共60个,利用"十五"地震数据处理系统处理的地震定位结果与四川台网定位结果比较,并参照陕西数字地震台网"九五"与"十五"地震数据处理系统对所选取30个地震定位结果的对比情况,对陕西数字地震台网"十五"地震数据处理系统定位稳定性问题进行探讨。更多还原

【Abstract】 60 earthquakes,including the main shock of M8.0 occurred in Wenchuan,Sichuan on May 12,2008 and aftershocks with magnitude equal to or greater than 2.5 occurred in Shaanxi and magnitude equal to or greater than 4.0 occurred in Sichuan in May,are selected for analysis.By comparing the earthquake-locating results of 30 events obtained on the platform of the earthquake data processing system established in the tenth five-year plan with the results from Sichuan Earthquake Network and referring to the comparison of earthquake-locating results obtained on the platform of the earthquake data processing system established in the ninth five-year plan with that obtained on the platform of the system established in the tenth five-year plan,the locating stability of the earthquake data processing system of the Shaanxi Digital Earthquake Network constructed in the tenth five-year plan is discussed.更多还原
