| Abstract: | The correlation slope of strain and water level in same borehole at the Urumqi station is computed by the regression analysis and the anomaly of slope is identified by the sieve variance method. The relation of correlation slope to the earthquake is researched. The results show that:(1)When correlation slopes of 4 organs simultaneously indicate anomalies then the probability of earthquake is high;(2)If the anomaly of correlation slope is positive, the effect of imaging earthquake is better;(3)correlation slope anomaly is attributed to the short-term and impending ones;(4)The ability of imaging earthquake of correlation slope has the difference of region. |
