INTERSEISMIC SLIP-RATE OF THE KUHBANAN-LAKAR KUH FAULTS SYSTEM:USING INSAR TECHNIQUE

The Kuhbanan fault with ~ 300 km length, one of the largest seismogenic faults in the southeast of Iran, has caused several catastrophic earthquakes with Ms 5-6.2 in 20st-21st centuries (Table 1). Moreover, the corresponding cross-thrusts were also associated with at least five clusters of medium-magnitude earthquakes. The Lakar Kuh fault with ~160 km length run parallel to the Nayband fault (Figure 1). The slip-rate of faults and also the spatio-temporal distribution of large-magnitude shallow-depth earthquakes on the Kuhbanan-Lakar Kuh fault system, attain broad concern for seismic hazard assessment (Figure 1). The horizontal slip-rate of the Kuhbanan fault is estimated ~1–2 mm/yr (Walker et al., 2012). Furthermore, the total horizontal displacement of the fault is reported ~5–7 km, as determined by the offset geological markers (Table 2).
