Comparison of Magnitude from Simulated Seismic Network and Digital Seismic Network in Shanxi Province
Li A · Earthquake Research in Shanxi · 2002
The situation of the magnitude recorded the earthquakes from the digital seismic network of Shanxi province since the 3 months of the test operation had been analyzed,the velocity magnitude determinated by the 2 men-machine interactive processing systems (Taide system and Gangzhen system) and the post emulated displacement magnitude from Gangzhen system were compared with the displacement magnitude determinated by the simulated seismic network in Shanxi (i.e. 9 artificial watch stations of Datong,Taiyuan,Linfen,Changzhi),the correlation,consistency and difference between these magnitudes were analyzed.A conclusion was obtained that the correlation coefficient of the above-mentioned magnitudes is above 0.940 and their correlation is quite good.
