| Abstract: | Based on the observation data of the digitalized strain-meter SS-Y from 2007 to 2013 in Guza Seismic Station, the annual change characters are summarized from the average of each day observation data. We relate these changes with the earthquakes occurred in Ganzhi Autonomous Prefecture and nearby areas and find that the statistical correlation between the data abnormal changes and earthquakes can be helpful to earthquake prediction in this region. |
