摘要
class=MsoNormal style="MARGIN: 0cm 0cm 0pt">Based on the Tangshan deformation data since 1984, the autoregression (AR) model and spectrum analysis with Daniell moving windows are applied .The order of AR model is compared around the time of Tangshan local earthquakes (ML≥5.0) and strong earthquakes in North China (ML≥6.0). The result shows that the orders based on the analysis on baseline data are larger before the earthquakes than those after the earthquakes.
