通过对在日本福岛地震发生前后短时间内的两个GPS测站的时间序列进行拟合以获取在短时间内的地震同震位移数据,通过动态时间序列图的形式对地震同震位移数据进行研究,结果发现,在地震发生时很短的时间内地震同震位移数据会发生大幅度的变化,在地震结束后又恢复正常。这种变化规律可以为地震前兆预测做参考。 By fitting the time series of two GPS stations within a short time before and after the earthquake in Fukushima, Japan to obtain the data of seismic coseismic displacements in a short period of time, the seismic coseismic displacements data The result shows that the data of the earthquake coseismic displacements will change greatly in a very short time after the earthquake and return to normal after the earthquake. This variation can be used as a reference for earthquake prediction.
