银川台重力观测前驱波的识别及特征
|
摘要
统计了银川台GS15-215型定点重力仪记录的数字化观测资料,分析了不同震级和不同震中距范围内的地震发生后前驱波的出现规律,发现银川台重力观测记录曲线中出现震前前驱波的比例比较小,尤其是震级较小的地震几乎无震前前驱波出现,对大地震前出现前驱波的比例、出现的时间及特征进行了归纳总结,以期为相关研究提供参考。
In this paper the appearance rule of precursor wave after earthquakes with the different magnitude and the different epicenter is analyzed based on the digital observation data of Yinchuan Seismic Station by GS15-215 type gravimeter.It is found that the proportion of appearance precursor wave in gravity observation record curves before earthquakes occurred in Yinchuan station is small.Especially there is almost no precursor wave before the smaller magnitude earthquake occurred.The proportion of appearance and the time of appearance and characteristics of precursor wave before the bigger magnitude earthquake are summarized.I hope this work could provide reference for the related research.
