Anomaly of Fixed Deformation Data and Explain Before the 2008 Wenchuan Earthquake

  • A Ms 8.0 earthquake struck Wenchuan on 12 May 2008 and anomaly of observation curve of fixed deformation stations is little.After the earthquake observation data before earthquake have been analyzed and processed.The result shows that deformation reveals anomalies before Wenchuan Ms 8.0 earthquake.The frequency of anomalies are high when stations are near from the earthquake epicenter and the frequency are low when stations are far from the earthquake epicenter.Finally the phenomena have been primary explained.
