Structural Concept of Active Faults Territory with an Approach to Global Studies

 Active faults as seismic faults, cause a great deal of damage each year through the creation of seismic impulses and surface ruptures in different parts of the world. These faults, due to the persistence of tectonic stresses, have a significant potential for re-motions, which subsequently cause more casualties. Therefore, understanding these faults the concepts associated with them is very useful in the strategic planning of a country. One of the most important of these concepts is fault territory. The most important causes of earthquake damage are construction within the fault territory. To understand this concept, other concepts such as fault scarp, fault migration, blind fault, fault system evolution, density maps, avoidance zones, geometrical parameters, and fault splay are to be considered. In this study, with an overview of these concepts as well as studies conducted in the east of Iran including the 470 m left-lateral displacement along the Dasht-e Bayaz fault, we attempt to provide a clearer concept of fault territory that includes these definitions.
