摘要
对比了兰州数字遥测地震台网所测定的速度震级与仿真位移震级、中国地震局平均震级之间的差异,分析了它们之间的相关程度、一致性、差异性。初步结果表明,兰州数字遥测台网测定的震级比中国地震局平均震级略高 0.05,这种偏差在测量误差允许范围之内,并且数字台网资料直接测定的速度震级与位移震级的一致性较好,震级测定的连续性要求基本可以保证。
The differences are compared among the velocity magnitude and emulation displacement magnitude mensurated by Lanzhou Digital Telemetry Seismic Network and the average magnitude determined by Chinese Seismological Bureau in the paper. The correlation, consistency and difference are analyzed among them. The preliminary result shows: magnitude mensurated by Lanzhou Digital Telemetry Seismic network is greater than average magnitude of CSB by 0.05, which is in the range of allowable error. Moreover, the velocity magnitude and the displacement magnitude mensurated directly by datum of digital network consist well with each other, and continuity requirement of magnitude determination can be ensured on the whole.
