天津测震台网地震监测能力分析
Evaluation of monitoring capability of Tianjin Seismic Network
摘要
Abstract
In this paper,we obtained the monitoring ability of Tianjin Seismic Network by calculating the minimum magnitude the stations monitored.Firstly,using Welch algorithm,a classic spectrum estimation,we calculated the noise level of 31 stations of Tianjin Seismic Network.Take 30 times valid values of the noise level as the maximum amplitude of S wave of the minimum seismic event that monitored.Then calumniated the seismic magnitude of each station using local magnitude formula,and took the fourth seismic magnitude of the station detected as the minimum monitoring magnitude.关键词
