数字地震台网大震前地脉动信息变化特征研究
|
摘要
通过计算机对数字地震台网产出的大动态、高分辨率、高精度的地震波形数据进行的实时采集跟踪分析 ,发现了有些台站大震前地脉动波形的周期和幅度有明显异常变化 ,探索大震前地脉动变化的特征和规律 ,将为区域性地震预报研究开辟一条新的途径
By means of computer sampling and analyses, the real time waveform data with high resolution and precision are obtained from digital seismic monitoring network. It is shown that the period and amplitude of microseism waveforms in some seismic stations have been changed before strong earthquakes. Detailed exploration of such changes might create a new approach for earthquake study and prediction.
