Abstract

Considering this fact that Iran lies on earthquake-prone belt of the Alp – Himalaya, how often, we observe destructive and devastating earthquakes in this country, therefore avaluation of Active tectonics and threat assessment, damages and occurrence of these activities in urban area is very important. Study area (1117 Km2) is located in north of Neyshabour city and southern highlands of Binaloud. A detailed study have been conducted by using seven quantitative morphometric indexes such as ratio of the basin shape (BS), the height integral (Hi), the asymmetric basin (AF), mountain forehead sinuosity index (Smf), valley floor width to height ratio (Vf), river sinuosity index (S), and the index gradient along the river (SL). The results of these studies were combined with each other in different layers. Then, according to evaluation of seven morphometric indexes, also using the ArcGIS, SPSS and Minitab software, the Active tectonic Zoning map of the area were drawn quantitatively and were separated in four categories (very active, active, semi active and inactive). Based on mentioned map, the southern part of the study area, with an area of 538/441 square kilometers equivalent to 36/32% of the area of study area, have very Active tectonic. The drawn Zoning map shows increasing in tectonic activity from north to the south-south west in southern domain of Binaloud. Adjusting this areas to compressional faults of north of Neyshabour, Neyshabour and numerous historical and instrumental seismic activity of this active faults is an important point which proofs the correctness of this research. We hope that these kinds of basic research studies conducted in different areas and authorities use them in heavy construction and urban planning.
