| Abstract: | The background deformation crustal velocity of North China in the period from 1985 to 2006 was calculated with the linear fitting method. Anomaly distinguishing scanning was made one iterm after another and the data including cross fault deformation observation anomaly amount and anomaly frequency were calculated according to the zones or areas. The results indicate that about one year before earthquakes of M≥6.0, anomaly frequency became larger and earthquake often occurred during or after the progress of high frequency anomaly. There is also certain reflections of the anomaly frequency on earthquakes of M≥5.0. |
