琼中台连续重力观测记录地震特征分析
The signature of seismic events recorded by the continuous ravimeter at Qiongzhong seismic station
摘要
Abstract
In this paper,we used the earthquake catalog(MS≥2.0)from 2009 to 2014 within 3 500 km away from the Qiongzhong seismic station to analyze statistically the correla-tion between the continuous gravity observation data recorded by Qiongzhong station and earthquakes.By investigating the characteristic of the seismic waves generated by earthquakes in the original second consecutive gravity data,we get the capabilites of Qiongzhong continu-ous gravity observation to record the earthquake within 3 500 km.At the same time,we ana-lyze the influence of earthquakes to the gravity observation data,tidal and non-tidal data pa-rameters .It is considered the earthquakes not only give rise to a pulse or step on the gravity observation data,but also on a non-tidal gravity residual curve,and cause little influence on the gravity M2 tidal factor.关键词
