| Abstract: | There were some of anomaly changes from the data of seismicity and underground fluid before the 2012 Ninglang M5.7 Earthquake. The character is seismic position shift with the seismic magnitude 5.0 from the eastern part to the western. Another character is middle- and short-term change anomalies of underground water contents. |
