Abstract :

Dasht- e- Bayaz fault with almost east- west trend and sinisteral lateral strik slip mechanism in eastern end has joined to Abiz fault with almost north- south trend. By considering to conjuction Dasht-e- Bayaz fault with Abiz fault in eastern end, sinisteral lateral strik slip motion of southern bloc of Dasht- e- Bayaz fault has caused that energy concentered in eastern part (in conjunction place with Abiz fault). Furthermore lateral strik slip motion of western bloc lengthwise Abiz fault has caused that a pressed zone formed in northern part of Dasht-e- Bayaz fault. As a result of arising stress of both fault to each other, that is right to be a relation and sequence between Abiz and Dasht-e- Bayaz fault activities. This affair proves with sequence of 1979/11/14 Korizan, 1979/11/27 Coli-Bonyabad, 1979/12/7 Kalate shur and 1979/5/10 Zirkuh earthquakes. Each of earthquakes on faults have caused that stress increase on neighbour fault. This affair by considering to software studies of clomb changes pattern of 1997 Zirkuh earthquake on Dasht- e- Bayaz fault show that Dasht-e-bayaz eastern part is in stress full part.
