بررسي نقش مستقيم و غيرمستقيم عوامل زمين‌ساختي و نوزمين‌ساختي در وقوع لغزشها مطالعه موردي: دامنه‌هاي شمالي قوشه داغ و دامنه‌هاي شمال غربي سبلان

Investigation of the Director Indirect Tectonic Effects and Neo- Tectonic on Landslide Events, Case Study: North Slopes of Gushe Dagh and North West of Sabalan

One factor in instability of slopes is tectonic activities and their outcomes. In most cases in different parts of the world, with due attention to tectonic distribution, instability of slopes are numerous beside fault lines and active parts. Therefore the researcher has tried to study the role of tectonic and neo-tectonic in accruing this phenomenon by using different methods. In study area (from 38° 15ʹ to 38° 39ʹ N and from 47° 09ʹ to 47° 30ʹ E, betweenAhar and Meshkinshahr), the distribution of landslides are visible and tectonic and neo-tectonic activities seems to play an important role in the existence of this phenomenon, so in this article, it has been tried to prove the tectonic and neo-tectonic role in occurring landslides by using numerical and descriptive methods. The results show that landslides occurrence are due to the numerous factors which tectonic is one of them, but locally in some parts of the area, tectonic and neo-tectonic play basic roles in landslides to occur.
