摘要
本文利用建昌台从1979年至1988年的限幅地震记录,以国家地震局地球物理研究所的《临时地震观测报告》测定的震级为标准,求出本台持续时间震级公式中的系数。结果表明:用振动持续时间测定近震震级,是一种简单易行的好方法。
According to the seismic recording limited earthquakes from 1979 to 1988,
in Jianchang Station and regarding the earthquake magnitude as the stand-
ard which was determined in 'Temporary Seismological Observation Report'
(Institute of Geophysics, State Seismological Bureau). We have worked out
the coefficient in sthe magnitude formula of the lasting time for our station.
The result shows that by means of lastingtime of vibration to determine mag-
nitude near by earthquake is a good and simple way.
