广东新地震参数目录的编制
|
摘要
数字地震台网除了能产出传统地震三要素外,还具备产出更多与震源和介质相关的参数的能力,如:品质因子Q、地震矩、应力降和震源半径等。这些参数的测定丰富了台网产出,提高了台网监测效能。本文回顾了在广东地震台网开展新地震参数目录编制的过程,对"九五"台网系统和"十五"台网系统得到的结果进行了对比,通过在JOPENS/MSDP台网数据处理软件中外挂震源参数模块,使新地震参数目录的产出实用化。讨论了求解新地震参数目录的一些注意问题。
Besides the traditional seismic three basic parameters,digital seismic network can give more parameters about seismic source and medium,such as frequency dependent Q,seismic moment,stress drop and source radius,etc.The determination of these parameters has increased the network output and monitoring efficiency.In this paper,the process of the new seismic parameters catalog is reviewed,the results achieved respectively by the network system in the "Ninth Five-year Plan" and the "Tenth Five-year Plan" are compared.By plugging seismic source parameter module in the routine analysis software JOPENS/MSDP,the output of the new seismic parameter catalog is to be practical.Some watchable problems in the process of new catalog determination are also discussed.
