Laboratory Observations of Linkage of Preslip Zones Prior to Stick-Slip Instability

Abstract: Field and experimental observations showed that preslip undergoes a transition from multiple to single preslip zones, which implies the existence of linkage of preslip zones before the fault instability. However, the observations of the linkage process, which is significant for understanding the mechanism of earthquake preparation, remains to be implemented due to the limitations of observation methods in previous studies. Detailed spatiotemporal evolutions of preslip were observed via a high-speed camera and … Show more

“…The process leading to the overall instability of the fault observed in the straight fault is usually accompanied with acceleration in rupture propagation and fault slip, e.g., [26,30,35]. However, this process of the bent fault observed in our experiment is different.…”

“…However, the standard deviations of CC decreased as R increased. Based on the principle of selecting the minimum R under the condition that the CC was sufficiently high via comprehensive consideration of the mean and standard deviation values of CC [26,28], R = 25 pixels was used to calculate the CC in the DIC method. The subregion was moved pixel by pixel in the calculated image when calculation was performed.…”
