We have investigated earthquake hazard factors, focusing on fault damage zones and respect distances. Fault damage zones are mainly controlled by locations on/off fault ,evolution stages, and fault kinematics. Geological faults and earthquake ruptures show asymmetrical displacement and damage patterns,making it difficult to estimate respect distances and surface deformation zones. We suggested geological-seismic parameters affecting earthquake damage features and proper distances for earthquake hazard assessment based on previous data and damage patterns. We applied the earthquake damage controlling factors to the recent coseismic surface rupture zones associated with the 2023 Turkey- Syria earthquake. This information will be useful for hazard assessment and appropriate site selection to reduce earthquake hazards in earthquake-prone areas. I N T R O D U C T I O N The key concerns related to earthquakes are timing, location, and magnitude because the damage scale and number of causalities generally depend on these characteristics (e.g. Pan Akkat & Adeli, 2008), although other controlling factors are also involved in determining individual earthquake damage patterns and intensities. The impact of each earthquake is influenced by a variety of factors, including seismic characteristics, fault type, magnitude, focal depth, distance from the epicenter, foundation condition, building styles, and applied anti-seismic design codes Implemented. These factors interact in distinct ways for each earthquake.
