陕西省及邻近区域合网的测震精度

ACCURACY OF THE DETERMINATION OF EARTHQUAKE EPICENTER AND ORIGIN TIME IN THE NETWORK OF SHANXI AND ITS ADJACENT PROVINCES

摘要:

地震参数的测定精度是由多方面因素决定的。其中测震台纲的几何布局也起着较大的作用。本文试图用蒙特卡罗法计算陕西省及邻近区域台网的几何布局对测震精度产生的影响。

Abstract:

In this paper,we have calculated the accuracy of the determination of earthquake epicenter and origin time in the network of Shanxi and its adjacent provinces by Monte Carlo method.In order to study effects on the accuracy of determination of earthquake epicenter and origin time caused by random errors of arrival time of each station and sta-tion number,respectively,the calculations under the condition of diffe-rent errors and station numbers have been completed.Besides,when a certain station has made an extremely large error,the change of ac-curacy of the network can be calculated.And the isorithm of errors of the determination of location and origin time under each condition can be drawn.
